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.

Tall Reeds (Phragmites) -- © Dave Spier

Tall (Common) Reeds, Phragmites australis, at Montezuma National Wildlife Refuge


          They're most noticeable beside the road in drainage ditches and low spots.  These tall plants with sword leaves and beige plumes extend their grasp year after year.  You may know them by several names including Common Reed, Tall Reed or Phragmites (the generic portion of Phragmites australis, the Southern Reed).  Look closely and you'll notice it's just another hollow-stem grass (though unusually large) with long leaves sheathing the stem.  The feathery plumes at the top are the flowers that turn to brown, then beige, then gray as the seeds ripen.
            During Colonial times and continuing into the 19th century, a native variety of Tall Reed grew along the coasts.  In the early 20th century, a nearly identical, but more aggressive European variety was introduced into one or more Atlantic ports.  Seeds clinging to boat hulls expanded its range along the Erie Canal.  Tall Reed has since exploded into disturbed wetlands where it spreads by seeds, dense tangles of underground rhizomes, and roots that can grow down several feet.  Colonies become dense stands that can choke waterways and crowd out any native wetland plants.  Reeds thrive in alkaline soils, so the abundant limestone and dolostone across Western and Central New York makes an ideal growing environment.  Cutting and burning are ineffective as controls.  Not surprisingly, winter salt runoff has no effect, considering reeds grow in brackish marshes along the east coast.  In fact, the salinity may suppress native freshwater vegetation, tipping the balance in favor of reeds.  This plant seems to be here to stay.

            European reeds have been used for roof thatching and cattle feed, and for making mats, pen quills and low-quality paper.  Native Americans of the Southwest fashioned arrow shafts, prayer sticks, screens and nets from the stems of reeds.  The rootstocks and seeds could be eaten as food. 
            Wildlife makes limited use of reed beds.  Red-winged Blackbirds will nest in the stands and may eat the seeds, thereby increasing dispersal of the plant.  In Europe and Asia, other species of birds are adapted specifically to life in extensive Phragmites stands.
