Bird Surveys at Ganondagan SHS, NY



Grassland Bird Surveys at Ganondagan SHS south of Victor, NY (southeast of Rochester) will expand in 2017. Two primary goals of the surveys are to support the designation of Ganondagan as a NYS Bird Conservation Area (BCA) in 2017 and to aid in assessing conservation and habitat-restoration efforts going forward.  Help will be needed and greatly appreciated. Data will be collected using eBird, a free program. ("About eBird" and data-entry instructions for both the free website and free Mobile App are linked at the bottom.*) While grassland birds are emphasized, it's important to record ALL the bird species detected along with their counts or estimated counts. For conservation purposes, we need to know population trends.

For general information on NYS BCA's, go to http://www.dec.ny.gov/animals/30935.html This is a state-level program on state lands, but otherwise it's similar to Audubon's Important Bird Areas (IBA) initiative.

The first 9 survey points (out of 61 planned) are active and can be used by any ebirder. Go to Hotspot Explorer - http://ebird.org/ebird/hotspots - and type in "Ganondagan SHS" and you'll see a list of all the locations. The two general hotspots are always available for any sort of birding at Ganondagan or for birds detected between survey points.

The protocol for the Ganondagan SHS grassland bird surveys, along with maps and sample data sheets, has been revised and can be emailed as a 4-page PDF. Stationary point counts will be 5-7 minutes long depending on habitat. Essentially it's five minutes in open habitat and seven in the more wooded settings. A series or sequence of two or more of the 5-7 minute counts at one point would aid detectability studies for each species reported.

There are five annual target surveys for each point: spring and fall migrations, breeding start and end, and one winter comparison. There is, however, no limit to the number of visits you can make, and ongoing, year-round coverage [weather permitting] would provide the greatest benefit for ornithological research and conservation. Please check the protocol PDF for all reporting details including weather notes and other information to include when using survey points. Non-ebirders can use paper forms or email their results to me at ebirder_14432@yahoo.com and I will forward them to Alexis VanWinkle, Supervising Conservation Steward, Ganondagan State Historic Site, 1488 Rt. 444, Victor, NY, 14564. She is headquartered at the Environmental Field Office, a.k.a. the old visitor center at the top of the hill near the blinking red light. Alexis is "more than willing to host introductory 'meetings' with anyone interested in helping on this project!" You can also contact Dave Spier or Alexis VanWinkle by facebook message.

White-eyed Vireo


White-eyed Vireo -- © Dave Spier

The White-eyed Vireo (Vireo griseus) has been expanding its range northward, possibly due to global warming. This one was photographed in the spring at Camp Allegany in Allegany State Park during the Allegany Nature Pilgrimage.

For more information, photos and sounds, visit the All About Birds website. An interactive range map (zoomable to your location) can be found in eBird's Explore Data section.

Yellow Warblers


Many warblers have at least some yellow, but I imagine if there's one that deserves the name of the color, it's the Yellow Warbler (Setophaga petechia).

The spring migration has come and gone, and now we have to be content with the summer residents that remain. Robins seem to be everywhere, and unfortunately so are the starlings and grackles. High in the tree tops, you might hear an oriole; they seem to prefer big cottonwoods here. If you have orioles near you, what trees do they prefer?  Orioles can be relatively common, but seldom do we get a good look at the male's flashy orange and black.

always the first weekend after Memorial Day) during a bird-banding demonstration

Another colorful songster, though relatively common, is likely to be overlooked unless you’re in the habit of scanning shrubby wetlands and thickets while listening for its "sweet, sweet, sweeter than sweet" song. Check the tops of shrubs and dwarf willows for a bright but tiny spot of yellow. With binoculars, look for rusty-red streaking on the breast. This is the male Yellow Warbler, one of 51 North American species of wood warblers – many of which are now uncommon or quickly pass through on their way north. The Yellow Warbler on the other hand is relatively common and a widespread nester from coast to coast across the northern 2/3rds of the U.S., Alaska and most of Canada with breeding populations extending down through coastal California and central Mexico. (If you're submitting an eBird report, you can use the "Add Details" button, and then the "Breeding Code" button to record any breeding behavior you observe or hear.)

Warblers are small birds, generally four to five inches long, with slender, straight-pointed bills used like tweezers to collect insects. Warblers are very active and it’s hard to get a good look at any of them. Most prefer woodlands in various stages of growth from scrub to mature forest and for this reason they are referred to as wood warblers. Within these habitats, some warblers stay in the treetops (giving birders "warbler neck"), some hide on the ground and the majority travel in-between. Yellow Warblers are somewhat unusual in preferring more open settings. Willow thickets and isolated shrubs in cattail marshes seem more to their liking, but any thicket will do in a pinch.

The Yellow Warbler is a common summer resident that begins returning at the end of April. The remainder trickles in throughout May. Aptly named, they are yellow on the head and underneath, olive-yellow on the back, and a mix of olive and yellow on the wings. Males are brighter with reddish streaks on the breast. The more aggressive and dominant males have darker streaks. Females are duller with faint rusty streaks on the sides. If you get a close view, look for yellow tail spots that are usually missed.

Brown-headed Cowbird egg in Yellow Warbler nest (Bradford County, PA)

The Yellow Warbler is one of the species most frequently parasitized by cowbirds, but they have developed a defensive strategy against the blackbirds. After a cowbird egg is deposited, the Yellow Warbler builds a new nest on top of the old and lays a new batch of their own eggs. If the cowbird returns, the warbler repeats the process. The record is a six-story nest (although there is an unconfirmed report of a 10-story nest near Cayuga Lake, NY, in 1923).

As a species, the Yellow Warbler is perhaps the most widespread of the warblers, but there are three distinct groups with four subspecies. Together they span the continent and range from the Arctic down through Mexico and the Caribbean to the northern reaches of South America. You can find an interactive range map on eBird.

On their territories, Yellow Warblers sing two types of songs with a number of individual variations. One song type is used to attract a mate, while the other is used to defend territories against other males. With wetlands being a limited resource, there is intense competition for prime nesting space. After mating, recognition of individuals becomes important, so minor variations in songs become important. You can find more information along with a static range map and recordings of Yellow Warbler songs on All About Birds.
 

Yellow Warblers have only one brood per year and as soon as the young are independent, the species begins its southward migration. They are one of the earliest summer nesters to leave. Some are gone by the end of July and (almost) all have left by the time goldenrod is in full bloom.

Grackles


The grackles are back - no surprise here since many types of birds are returning from the South. These are the "half-hardies" that tolerate some cold weather or a late snowstorm. You may have noticed Snow Geese, a variety of puddle ducks, Turkey Vultures, Killdeer, and lots of blackbirds. Mixed in with flocks of redwings, and often out-numbering them, are the larger grackles with their long tails that can fold into keel-shaped V’s when they fly, especially on the males. The long tails can make the wings look short.

In bright light, inland Common Grackles (Quiscalus quiscula) exhibit glossy blue heads and iridescent-bronze backs. Depending on the type and direction of the light, the head color can vary from green to purple. Males are larger and shinier than females. Young birds in summer and fall are dull and dark brown with dark eyes. Adults have pale yellow eyes. Near the Atlantic coast, there is a race of Common Grackles called "purple" because the bronze color is replaced by deep blue or multi-coloring on the back. Southeastern male grackles may exhibit purple around the neck.

Bronzed race of the Common Grackle -- here a male is "singing" to proclaim a territory

Common Grackles occupy a wide variety of habitats, both upland and wetland, and are particularly well suited to living near humans. They are omnivores and eat just about anything they can swallow. Both redwings and grackles, along with cowbirds, will pick up dropped seeds under feeders in late winter and early spring when there is a shortage of other foods. Like gulls, they will follow plows to catch fleeing insects and mice. Later in the spring, their taste for corn sprouts will make them pests. In the summer they eat ripening corn. They steal worms from robins and they kill and eat smaller birds, especially nestlings. In the fall, they use their hard beaks to open and eat acorns.

Common Grackles spread out during nesting season, but regroup by the thousands for autumn migration. Winter roosts shared with other blackbirds in the South can number in the millions.

For more information visit All About Birds. Although classified as a song bird (passerine), the grackle's voice is more akin to shrieks and squeaks. Click on "Typical Voice" for a sample. For an interactive range map, go to eBird's "Explore Data" tab.

Common Grackles are found east of the Rockies. A larger grackle species, the Boat-tailed, is found along the Atlantic, Florida and Gulf coasts. Female Boat-tail's are brownish on the body and head. A similar species, the Great-tailed, is found from Southern California to Oklahoma and south into Mexico. Female Great-tail's are grayer than female Boat-tail's.

Good birding!

Tree Sparrows


They migrate across southern Canada and winter in the colder portions of the lower 48 from Washington to Maine and south as far as Oklahoma. Contrary to their name, you're just as likely to find them in some bushes or feeding on the ground with the juncos. Their natural food is fallen weed seeds picked off the snow. If the snow grows deeper, they will cling to the taller plants while they pluck the seeds. In the winter they obtain water by eating snow.

Tree sparrows do not defend winter territories, but they do form dominance hierarchies and they sometimes spend the night as a group under the snow to escape bitter cold wind. Otherwise they individually roost in conifers or marshes.

In April they will head north to breed in the Arctic, generally above the tree line. They even nest on the ground, albeit in open, scrubby areas with alder thickets, dwarf willows, birches and stunted spruce. During the short summer, they eat primarily insects and spiders instead of seeds. For a bird that spends so much of its time on the ground, why would it be named "tree sparrow"? I have yet to find a good reason, but I often see them perched in trees or bushes. I suspect that early ornithologists first encountered this species sitting on tree branches.

Not quite as drab as some sparrow species, the American Tree Sparrow (Spizella arborea) sports a rusty cap, chestnut line behind the eye, some rufous on the shoulders and sides, an isolated dark spot on a gray breast, and a white wing bar. (At close range, you might notice part of a second wing bar.) One of this sparrow's distinctive field marks is a bicolored bill, dark on top and yellow on the lower mandible. This species' back is light brown with dark streaks, and the long, notched tail has dark-gray feathers with pale edges. Males and females are nearly identical and juveniles are similar but more streaked.

Tree sparrows are preyed on by Accipiters, kestrels, screech owls, weasels, foxes and even Red Squirrels. The average life expectancy is two to three years, but one tree sparrow was recorded as surviving 10 years and nine months.

For more information, photos, similar species and typical voice sounds, visit All About Birds. eBird provides an interactive range map of this strictly North American species (zoomable to your location).

Redpolls


It's been a good year for redpolls. Every few years there's an irruption of winter finches from Canada when their food resources are scarce up north.
 
I'm in Upstate New York, and here they hang out with the goldfinches. In fact, they’re related to goldfinches (in the sense that both are in the finch family). They’re about the same shape and size and they eat the same kinds of seeds, but there it ends. Redpolls resemble streaky sparrows with a red cap and black around the bill and the males have an added raspberry wash on the breast. Winter brings them to New York from northern Canada and this is about as far south as they normally need to go. These are tough little birds.

Although they seem perfectly at home in the bushes near our feeders, the redpoll’s natural preference is open fields and patches of weeds. They’re more likely to appear in alternate years or irregularly when seed production from spruce and birch trees across northern Canada and Alaska is reduced. Redpolls also eat the seeds of willows and alders. When they're on the snow under our feeders, they're picking up sunflower seeds dropped by the other birds.

To make it through long, cold nights, redpolls have evolved a version of the crop, a throat pouch (on the esophagus) where a supply of seeds can be stored. After finding a sheltered perch, usually in a conifer, and then fluffing up their dense feathers for added insulation, they slowly digest the stored seeds at their leisure. The combination of food and fluff maintains a core body temperature of 105º F. This allows redpolls to survive colder temperatures than other songbirds.

During the summer they are abundant in boreal forests and open tundra around the subarctic regions of both North America and Eurasia.


Ornithologists, the people who study birds, still can’t decide how many redpoll species exist. At the moment, there are two. The Common Redpoll, Carduelis flammea, is the bird normally seen at winter feeders and traveling in flocks across fields. The rarer Hoary Redpoll, Carduelis hornemanni, is generally lighter in color, giving it a "frosted" appearance, hence the name hoary. Due to individual variations, there is almost an overlap between the two types of redpolls, and some ornithologists believe there is just one species with a number of races. Perhaps DNA studies will help to sort this.

For a small finch that weighs less than an ounce, the redpoll has wonderful adaptations that allow it to survive the toughest winters, not to mention unpredictable summers in its far northern homeland. The next time you’re feeling cold, remember the bird that finds warmth in Upstate New York winters.

For an interactive range map of the Common Redpoll, visit the eBird website and zoom in to your location. Recent report locations (within the past 30 days) are coded red. You also can set a custom date range to find recent reports.

Golden-crowned Kinglet


© Dave Spier

Okay, it's a lousy photo. Normally I would delete it and go on, but it brings up an interesting point about birding. I was walking the trail beside the Canandaigua Outlet in Three Mills Park northwest of Phelps, NY. The weather was overcast and birds in the tree tops were mere silhouettes at best. A small, nervous bird, constantly on the move, caught my attention. It acted like a kinglet, and I might have passed it off as a Ruby-crowned, the expected species (although I'd use "kinglet sp." for eBird, or maybe "passerine sp." because I wasn't even sure it was a kinglet). I managed a few shots with the flash on, but most were basically under-the-rear-end views, not much help in ID'ing. I did get lucky with what turned out to be a side view and an out-of-focus or blurred head/front shot, although I didn't realize it until I was leaving the park and bumped into another birder. We looked at the photos and voila, a Golden-crowned Kinglet (Regulus satrapa), the first for this park according to the eBird bar chart.

I always carry a camera, except maybe in the yard when I'm doing other things. It's not my biggest lens, but something manageable (a 300mm + 1.4x), and it's mounted on a gunstock with a strap so I can carry it on my shoulder and whip it into position at a moment's notice. I now make a habit of keeping an external flash on the camera, even though it makes it more difficult to use if I'm wearing a hat (usually a baseball-style camo cap). A small, compact point-and-shoot camera with a long zoom might be a better solution, but I don't have one. Besides, my light-weight T2i (DSLR) is highly responsive and, when I do things right, gives sharp, low-noise photos.


Kinglets are tiny gray birds with olive-green touches and a lighter belly. The golden-crown is named for a yellow streak outlined in black on the top of the head. This is accented with a white stripe above the eye and bill. The similar Ruby-crowned Kinglet (Regulus calendula) has a gray head, white eye-ring and under the best of conditions, a red patch on the crown of the male. Learn more on the All About Birds website which has photos, voice recordings and a range map. There's also a range map on eBird, but there are gaps in the Canadian coverage due to fewer birders.

The Golden-crowned Kinglet was unexpected because it prefers conifers, and there are none in the park. Its breeding range spans the Canadian boreal forest all the way to the Rockies and the Pacific. There's a year-round range down the west coast and an eastern year-round range from the Canadian Maritimes down through the Appalachians. Most of the continental U.S. is potential winter range. I have seen this species in deciduous trees, but usually there are conifers within sight. (This was also the case in our yard, where we have a mix of both deciduous and "evergreens," on the one occasion that a golden-crowned stopped on its way through.)

female Ruby-crowned Kinglet (October, in our yard) for comparison

Three Mills is a small Ontario County park, not much more than a few acres of wooded floodplain along a major creek in the northern Finger Lakes region of New York. However, for its relatively small size, it's a gem with a variety of good bird habitats. It was donated by the Ontario County Federation of Sportsman's Clubs and mainly provides fishing access - until more birders discover it. The flowing creek stays open during the winter and attracts waterfowl, including Common Mergansers. I also drive the nearby roads, particularly Falkey Road along the south bank of the creek. The fields just to the south and along Stryker Road sometimes have Snow Buntings in the winter.

Evening Grosbeaks



© Dave Spier

Natural food shortages (of the bird kind) are encouraging Canadian finches to head south for the winter. One of the most colorful is the Evening Grosbeak (Coccothraustes vespertinus), somewhat resembling a giant goldfinch, which is not too far off, since they are related. Goldfinches are five inches long (slightly shorter than a chickadee), whereas these grosbeaks are eight inches.

The male Evening Grosbeak [photo above] is very noticeable with white patches contrasting against otherwise black wings and short, black tail. His body is burnt-gold (yellow) grading to a dark-brown head with yellow forehead and wavy line above the eye. Females [below right] are subdued, with mostly gray on the body and head. The only yellow is confined to her neck. Both sexes have massive, pale-colored bills.

Grosbeaks eat mainly seeds, nuts, berries and buds, and they readily come to feeders (if they're around). We had eight Evening Grosbeaks for several days right after Hurricane Sandy and then they vanished in their nomadic fashion. Three returned briefly and a week later, there were four down the road. Unpredictable is a good way to describe this bird.

As always, you can find photos, range map and voice recordings on the All About Birds website. In addition, find current range information on the eBird Range-and-Point-Maps under Explore Data. Use the search boxes to see a range map for this (or any) species you type and then zoom in to your location. You can narrow the date span with the "Custom Date Range" tool or look for any possible sightings in your area by using the Location tool. Write to me for specific information and links. I also encourage you to submit your own sightings. This is how I keep track of their wanderings in my neighborhood, and the information benefits science.

Marsh Wrens



As a group, wrens are small, noisy, brown birds that often hold their short tails upright.  Their bills are thin and curve down to a point for picking and eating insects and spiders.  The House Wren is the most familiar; it is plain brown and nests in tree cavities or nest boxes, often in proximity to human dwellings.

Its cousin, the Marsh Wren (Cistothorus palustris) lives – where else – in cattail marshes.  Its gurgling, rattling trill can be heard any time of day or night.  (If you think you might have heard this wren, you can listen to a recording of its song on the All About Birds website.)  On rare occasions when it perches on a cattail top in the open, you’ll notice a dark cap and light line above the eye.

During breeding season, nests are lashed to vegetation and sometimes hidden in shrubs.  Construction includes a woven dome of grasses and sedges with the entrance on side.

The Marsh Wren population is declining in the east, but increasing in the west.  Major differences in the two subspecies’ songs may indicate two separate species.  The combined winter range extends along the Gulf coast into the Southwest and down through all of Mexico.  A year-round population hugs the east coast from the Mason-Dixon line [the Pennsylvania/Maryland border] south to Florida. During migration, a Marsh Wren can stop in any of the lower 48 states.

The Marsh Wren photo was taken September 3rd from the dike separating the two main impoundments at the Montezuma Audubon Center north of Savannah, New York, where they can be heard, and sometimes seen, throughout the late spring, summer and early fall. You can get an idea of their seasonal distribution (and all the other species) in the Wetlands Complex by looking at the eBird bar chart for Wayne and Seneca Counties, New York.

On Saturday, September 29, there will be an organized canoe trip in the Montezuma Wetlands Complex from 2 pm – 4:30 pm.  Join the Montezuma Audubon Center’s Teacher-Naturalist, Frank Morehouse to explore the Seneca River along Howland’s Island, New York.   Learn about the birds and other wildlife of the area on a leisurely paddle.   There is a fee; canoes, paddles and life jackets will be provided (and binoculars if needed).   Bring water and snacks.   Pre-registration is required by calling (315) 365-3588 or email montezuma@audubon.org for details. The MAC website is http://ny.audubon.org/montezuma

Eastern Kingbirds




Eastern Kingbirds -- © Dave Spier

Eastern Kingbirds are easy to recognize; they are charcoal above, black around the eyes and crown, and white underneath including a white throat. The clincher is a black tail with a white tip. They are smaller than robins and often fly across a field with wings fluttering. If you are familiar with its relative, the phoebe, another type of flycatcher, the kingbird is larger. The Great Crested Flycatcher is about the same size as the kingbird.

Eastern Kingbirds (Tyrannus tyrannus) show a slight preference for nesting near open wetlands, but can be found in many rural settings with open areas and nearby trees. Given a choice, they favor the edges of ponds, streams and marshes. If there’s an island with trees, this is prime real estate because the water affords protection from four-legged predators. There are no islands at Lock Berlin Park (beside the old Erie Canal in Wayne County, NY), but I found a pair of kingbirds nesting high in a dead tree between the old canal and a small wetland east of the picnic area. The nest was in a fork of the trunk and partly hidden by Virginia Creeper vines.

Lousy photo of a kingbird nest...

Their scientific name, Tyrannus, is the same as tyrant and refers to their aggressive behavior, even toward birds as large as hawks and crows which are potential nest predators. The name "Kingbird" refers to a seldom-seem patch of golden or orangish feathers on the crown. The color resembles flowers and may be used to attract insects which the kingbird eats. The birds are members of the flycatcher family and often hunt from an exposed branch or wire. When an insect buzzes by, the kingbird flies out, grabs it in its beak and returns to the perch or takes it to the nest.

There’s a kingbird in the fields around the Montezuma Audubon Center (Savannah, NY) and it sometimes sits on top of the Purple Martin house to watch for insects. The martins tolerate its presence, but it would do little good to try and chase it. In fact, kingbirds are essentially bullies and have been known to attack other insect-eating birds and steal their prey.

Kingbirds are known to eat over a hundred species of insects. Unfortunately, dragonflies are on their menu. The dragonfly’s nickname, "mosquito hawk," will tell you why we’d prefer them to be left alone. About a third of the kingbird’s diet is from the order Hymenoptera (bees, wasps, flying ants, etc.). The kingbird’s nickname of "bee martin" refers to its habit of hanging around beehives and eating honey bees as fast as they can. Before songbirds became protected, there was a bounty on kingbirds. It turns out that kingbirds eat primarily drones, the stingerless males, with little consequence to the colony. Drones are identified by being darker and larger than worker bees (which can sting).

Eastern Kingbird at Montezuma National Wildlife Refuge, Seneca Falls, NY.

A quarter of the kingbird’s intake is beetles, including types we consider harmful. Grasshoppers and crickets average 12% of the summer diet. Yes, flycatchers eat flies, but those only amount to 10% or less – little more than appetizers. If there’s a shortage of insects, then frogs, snails and small fish might become prey. Perhaps as a last resort, small fruits and seeds (like wild grapes and pokeberries) are eaten.

The Eastern Kingbird's summer range covers the eastern half of the United States and extends northwest across the upper Plains and Rockies well into Canada.  They are mostly absent from the Southwest. The eBird range map shows a concentration down through the Great Plains.  Migration takes them down through eastern Mexico and Central America to their winter range across a large portion of South America, including the western Amazon, and as far south as the Argentine Pampas. During our winter (South America's summer), kingbirds are much more dependent on eating fruit.

Cerulean Warblers



Cerulean Warblers © Dave Spier


The Cerulean is an uncommon and vulnerable* warbler that is declining throughout its range in the Midwest and mid-Atlantic region. You can find a range map on eBird, and by zooming in far enough, you can locate actual checklists reporting this species.

The Cerulean's core summer range is soft-coal country – eastern Tennessee and Kentucky, southern West Virginia and Ohio and southwestern Pennsylvania – an area noted for strip mining and mountain-top removal which impacts the mature forests they need for breeding. This species is being considered for listing under the Endangered Species Act, and the National Audubon Society has already added the bird to its Watchlist.  

The Cerulean is named for the male's sky-blue color which is set off by white on the throat, belly and wingbars. Black streaks on the flanks, a black "necklace" and black in the wings and tail add contrast. The female is much duller and lacks the distinctive blue. Pale yellow replaces much of the white. Their preferred habitat is deciduous forests with tall trees and open understory like those found in wet bottomlands. Actually seeing the bird is difficult because it feeds and nests in the treetops, higher than most warbler species. You’re more likely to find the bird by its song, a rapid series of buzzy notes leading to a higher trilled note at the end. To listen to a recording, go to All About Birds.

The nest is an open cup made from fibers, grass and hair held together with spider silk. If the first nesting fails, the spider silk is reused in making a new nest. When the female leaves the nest after incubating for a time, she briefly drops like a stone before opening her wings to reduce the chances of attracting attention to the nest. The average clutch of four speckled eggs hatches in less than two weeks.

After breeding season, the Cerulean makes the long trek south through the southern states, flies across the Gulf of Mexico, migrates along the Central American highlands and ends up in its winter home in the evergreen forests of the northern Andes. Over 60% of this winter habitat has been converted from forest to farms and pastures, further impacting the species and adding to its decline. Ceruleans will use shade-grown coffee plantations, so in the interest of bird conservation, please consider buying one of the shade-grown coffee brands. Better yet, choose organic shade-grown if you have a choice.

I've known about the Cerulean Warblers (Dendroica cerulea) at the Montezuma National Wildlife Refuge (between Rochester and Syracuse, NY) for some time, but they also live nearby along the Clyde River and Erie Canal in southeastern Wayne County (the Towns of Galen and Savannah). I had stopped to see Dave Odell, retired NYSDEC Region 8 Wildlife Manager, at his Old Duck Inn, a bed & breakfast southeast of Clyde in the Montezuma Wetlands Complex. I wanted to see what birds I might add to a checklist I started for the Montezuma Birding Trail, so I was happy to learn that Dave has been hearing the warblers. His 100-acre farm on Tyre Road extends downhill to the Old Clyde River. The wooded shoreline provides good habitat for this species.

Catbirds



Catbirds -- © Dave Spier

While many neotropical migrant birds are declining in population, a few hardy American species are doing well and perhaps expanding. One species in particular has adapted to human landscaping, assuming you have at least a scattering of trees and shrubs around your yard.

More likely to be heard than seen, its song is what I call jibberish -- a random assortment of notes and calls with no discernable pattern. Occasionally it will imitate portions of other bird calls, and that explains why it is one of three members of the Mimic Family. The most famous member is the mockingbird which precisely copies other bird songs (and other sounds, even frogs and sirens) and repeats them three or four times before moving on to a new sound. The second member of the mimics is the Brown Thrasher, now an uncommon bird in this part of New York. The thrasher sings each song twice and then moves on. The Gray Catbird (Dumetella carolinensis), on the other hand, says everything once, although it eventually returns to the same phrases in random order. Very little of its rambling repertoire is actual mimicry, although I have to be careful when he throws in pieces from a Wood Thrush. The catbird gets its name from its cat-like "meow." There have been times when I mistook it for a real cat.

At least one catbird likes our overgrown back yard, even though I keep portions mowed and maintain a wide trail inside the perimeter. I've been doing a lot of yard work and gardening and the bird seems to be getting used to me. It will "sing" from a nearby branch, sometimes out in the open. It's coloration is mostly dark gray with a black cap and some rusty red under the black tail. I guess this helps it blend into the shadows. Its tail is proportionately longer than most songbirds. Males and females are nearly identical. They're about the size of a robin but more slender.

The mulberries are just starting to turn from pink to red. If last year is any indication, when they begin to darken further, the catbird will start checking to see if any are ripe. Fruits and berries make up half their diet. The catbird in the opening photo has what looks like a Juneberry, most likely from the tree on the property line with our neighbors. The other half of their diet is insects, especially grasshoppers, crickets, and beetles. One or two catbirds may linger in the area through the fall into early winter if berries are plentiful. Once it gets really cold, the stragglers head for the Atlantic coast and piedmont east of the Appalachians. Some go as far as Florida and the Gulf coast.

Rose-breasted Grosbeaks

Rose-breasted Grosbeaks -- © Dave Spier

One of our favorite birds returned from the south earlier this month. In fact, three of them were at the feeders at the same time, but we’re still waiting for a female which resembles an overgrown and overstuffed sparrow, but the males are a dramatic combination of black and white with outstanding rose-colored bibs, hence the name, Rose-breasted Grosbeak. The term grosbeak is a contraction of the words gross and beak with "gross" coming from an old French word meaning big or thick in reference to the stout, conical beak of these birds.

Female Rose-breasted Grosbeak banded by the late Bob McKinney, a long-time friend, at a previous Allegany Nature Pilgrimage (held annually on the first weekend after Memorial Day in southwestern New York).

Their primary food is seeds which they crack with that heavy bill. We often see them at our sunflower seed feeder. In the spring they also eat flower buds and I’ve photographed them in one of our cherry trees while the fruits were still totally green. During the summer they feed on small fruits and insects. I have one old report of grosbeaks eating young gypsy moth caterpillars as fast as they could catch them. They've also been observed catching cucumber beetles, canker worms, tent caterpillars, army worms, cut worms and cinch bugs. (Those so-called worms are actually caterpillars.) More power to these birds! If you want to plant some trees and shrubs to entice these birds, they seem to prefer the seeds, fruits and flower buds of serviceberry, elderberry, mulberry, dogwood, hawthorn and wild cherry. They also eat the seeds of beech, hickory, elm and maple.

The male grosbeak's song has been likened to a robin after singing lessons. It is a slow, rich warble. The female also sings, but her version is softer and shorter. Their short call note, on the other hand, is more like a sneaker squeaking on the gym floor.

Rose-breasted Grosbeaks are said to favor open woodland and the edges of swamps and tree-lined streams. They’re a frequent visitor or resident at the Montezuma Audubon Center just north of Savannah, NY. Our yard has a lot of grown trees and, even though we're up on top of a drumlin hill, it appears to meet their needs. Hopefully they'll raise another family here like they did last summer. They build a rather flimsy nest and sometimes you can see the pale blue eggs through the bottom. The male helps incubate the eggs during the day, accounting for about 1/3 of the time on the nest. The female does the remainder and continues throughout the night. When not on the nest, the male is either standing guard nearby or bringing food to his mate. Another old report mentions carrying potato bugs to feed her on the nest. After fledging, young grosbeaks resemble the female and young males begin to show a tinge of pink in the fall. By this time, the adult male begins to lose his brilliance as he takes on buffier tones while his rose color turns to dull pink, making it easier for him to hide in the open tropical forest of the species’ winter range across Central America, Cuba, or the near reaches of South America.

November Trails -- Part 1


November Trails
© Dave Spier

Unexpectedly warm and sunny weather followed the first feeble attempt at an autumn snowfall. Call it Indian Summer, or just call it enjoyable. Mornings were chilly and dew-laden, but that's normal November. I hope you have a chance to get out and savor the weather before things go downhill again.

The trail through the field back to the woods is dotted with open milkweed pods releasing brown seeds to float on white down. The zebra-striped Monarch caterpillars that fed on the toxic white sap of the summer leaves long ago transformed to butterflies and headed south toward their winter home in Mexico. You might have noticed the Canadian Monarchs passing through New York in early October.

Near the milkweed, the once-plump, off-white berries on Red-panicled Dogwoods are now wrinkled and dry. Chickadees have been snatching as many of the fruits as they can, and the ones that fall to the ground become food for grouse. The shrub's name comes from the red stems that hold the berries, but the gray bark on the main branches gives it the alternate name, Gray Dogwood. [see the previous blog post] Next to the dogwood, a flock of Purple Finches landed in a small tree and then flew again in unison. These birds, red-raspberry relatives of goldfinches, breed across southern Canada and winter in the eastern half of the United States. We see them most often during their migrations.

In the middle of the field, a thorny rosebush is covered with tasteless rosehips that are nonetheless high in vitamin C. These small, red fruits are credited with supporting the expansion of the mockingbird from its southern strongholds to the cold climates of Upstate New York.

In the woods, small beige moths flit among the trees while a pair of Red-bellied Woodpeckers chase each other from one tree trunk to the next. In spite of brilliant scarlet feathers on the nape (back of the neck) and crown of the male, the bird is named for an obscure patch of salmon red on the belly between the legs. The bird has to be at just the right angle to see it. The problem with the name is that another woodpecker with an entirely red head and neck took the name Red-headed Woodpecker. That species is a southern bird; we seldom see them in the Finger Lakes region.
