Red Maple (Acer rubrum)

Red Maple (Acer rubrum), a.k.a. one of two Swamp Maples or soft maples, is probably the most abundant native tree in the eastern U.S. The species can adapt to a wide range of site conditions from bottomland swamp forests to upland mountain slopes. It does well in young forests where it can get some sun, but shade-tolerant species crowd it out of mature and old-growth forests. This particular Red Maple was growing beside the Moss Lake loop trail between Old Forge and Inlet in New York's Adirondack Mountains. Trail access is from Big Moose Rd. NW of Eagle Bay. (Sept. 25th)

About eBird

eBird allows you to keep all of your birding records in a way that makes them available to scientific research and conservation. The eBird motto is 

"Global tools for birders, critical data for science." (and it's free!)

The following is adapted from the eBird website About page (http://ebird.org/content/ebird/about/)

Overview
Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird gathers data from birders around the world to develop basic information on bird abundance and distribution at a variety of space and time scales. eBird’s goal is to harness the vast numbers of bird observations made each year by recreational and professional bird watchers. In return, birders have free and permanent storage of all their sightings and birding lists (such as life, country, state, county, etc.).
Each participant's observations join those of others in an international network. eBird then shares these observations with a global community of educators, land managers, ornithologists, and conservation biologists. This data set is becoming the foundation for a better understanding of bird distribution across the western hemisphere and now beyond.

How Does it Work?
eBird documents the presence or absence of species, as well as bird abundance through checklist data. A simple web-interface, or the alternative mobile app, engages tens of thousands of participants to submit their observations. Results can be viewed via interactive queries on the eBird website. Users are encouraged to participate by providing internet tools to maintain their personal bird records and enable them to visualize data with interactive maps, graphs, and bar charts.
A birder simply enters when, where, and how they went birding, then fills out a checklist of all the birds seen and heard during the outing. eBird provides various options for data gathering including point counts, transects, and area searches. Automated data quality filters developed by regional bird experts review all submissions before they enter the database. Local experts review unusual records that are flagged by the filters.

To get started using eBird, see these articles:

entering data via mobile app: http://help.ebird.org/customer/portal/articles/2411868
I'll elaborate in future blog posts starting with creating a free account.

Data Accessibility
eBird data are stored in a secure facility and archived daily, and are accessible to anyone via the eBird web site and other applications developed by the global biodiversity information community. For example, eBird data are part of the Avian Knowledge Network (AKN), which integrates observational data on bird populations across the western hemisphere. In turn, the AKN feeds eBird data to international biodiversity data systems, such as the Global Biodiversity Information Facility (GBIF). In this way any contribution made to eBird increases our understanding of the distribution, richness, and uniqueness of the biodiversity of our planet.

Explore Data has an interactive range map for any species (zoomable to your location).

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.

Turkey Vultures

(Introduction) -- © Dave Spier

I've been doing a little birding with my grandson and several times we've encountered one or more Turkey Vultures. Are you still finding TUVU's after the spring migration? If so, where, what time of day and under what circumstances?

Turkey Vultures (Cathartes aura) are fairly easy to recognize, assuming decent light and proximity.  If you encounter them gliding along in search of dead animals to eat, look for several things. From the front (approaching you) or the rear (going away), the wings are held in a shallow V called a dihedral. When passing overhead, the wings are two-toned with the forewing ("solid" portions) dark while the flight feathers along the trailing (rear) edge and wingtips are lighter gray or even silvery. The head appears small because it lacks feathers. At closer range, the adult's head is red while juveniles are gray or dark headed.

For their size, vultures are relatively light weight. They are easily buffeted by wind so their flight often appears wobbly.

Their diet consists of carrion, primarily road-kills in populated areas, which they find with their keen sense of smell. The lack of feathers on the head is a sanitary adaptation related to probing into corpses. Feathers would hold scraps that become diseased.

Turkey Vultures are certainly common in Western New York. As of June 3, 2016, a total of 25,718 passed the Braddock Bay Hawkwatch during spring migration on their way east and north. Some will stay and nest in Central New York while others keep going. The vast majority will return south next fall, but a handful can be found in Letchworth State Park year-round. In the winter, they shelter out of the wind by roosting on cliff ledges below the rim. In the morning, the sun warms the rocks and the vultures begin to ride thermals (warm air currents) that help them gain altitude. For more spring photos taken at Letchworth, including several in this blog, see eBird checklist S10396306.

For more information, a range map, photos and sounds of Turkey Vultures, visit the All About Birds website. An interactive range map (zoomable to your location) can be found in the eBird Explore Data section here (or go to that page and type in any other species of interest).

Although it's possible to encounter a Black Vulture (Coragyps atratus) in Western New York, it's far less likely. (Only one passed Braddock Bay this spring.) Several quick ID distinctions are that only the wingtips are lighter-colored in Black Vultures and the head is never red. For more information and a range map, there's also an ID page for this species.

Story in the Snow

A Story in the Snow

© Dave Spier

Birder's journal March 21, 1971: I was following the redtail along the ridge, not so much to get a photo of it as we were both heading in roughly the same direction. I was a minute or two behind the hawk when I exited the woods and entered a partly-scrubby opening on the north end of the drumlin. More by luck than anything else, I came upon the story written as clearly as if words had been used. The mouse tracks ended in a depression, surrounded by the hawk's wing and tail feathers imprinted on the surface as it lifted into the air, prey in tow, while a drop of blood on the snow was all that remained of the hapless creature.

This could have been written a week ago; we've had no shortage of snow and cold weather this winter. There is a timeless element to many of nature's stories. It's likely a story that has been written over and over again across the intervening years.
