Re: [cayugabirds-l] Stewart Park goose study

[Dave Nutter]

If my guess is correct that 200 local geese have yellow neck bands, then I've 
found 90% of them so far, overwhelmingly at or next to Stewart Park, where I 
assume they were corralled and collared. This capture was possible because the 
adult geese molt all their flight feathers at once and regrow them while their 
young are also growing up. Having chosen a relatively safe place to spend this 
vulnerable season, it's not surprising that they would mainly stay there. 
Perhaps 10% were miffed enough by the process that they swam to other sites.


Yesterday evening for the first time I saw 2 collared geese away from Stewart 
Park, NY66 & NU53, among a flock of Canada Geese on Cayuga Inlet near the south 
end of the bike path along Floral Avenue (NYS-13A). As it turned out these 2 
were also birds which I had not seen at Stewart Park. Maybe these birds left 
Stewart Park soon after the banding. However, I was still finding additional 
new-to-me collared birds at Stewart Park yesterday morning, so maybe they were 
hidden among birds there and at Newman Golf Course, and went south later. 
Anyway, this evening I saw one those same 2 collared birds (NY66) on Cayuga 
Inlet near Treman Marina, along with 4 collared birds I was not able to see 
well enough using only binoculars in the fading light. Gotta remember to always 
bring a scope when biking!



By the way, a scope comes in handy after dark on clear evenings. That odd 
bright yellow "star" just to the left of the top of Scorpio is Saturn. At 60x 
there's a distinct view of the planet surrounded by the oval of the rings 
tipped fairly high toward us. A few years back the rings were edge-on and 
boringly invisible, dull to look at, like Mars is in my scope, currently to the 
right of Saturn in the southern sky in the evening.

Many of the Canada Geese at Stewart Park have recently been banded. The young 
were given a red band on one leg and a standard aluminum band on the other. One 
of these young is dragging an injured wing. Up to 200 adults were given yellow 
neck collars each with a unique black 2-letter, 2-number code. All appear to 
start with either NY or NU. I've seen 162 different collars so far.



This is evidently part of the study of the local goose population, their 
number, where they go, and maybe some demographics. It has to do with the push 
to get rid of the geese which was talked about at a recent club meeting. 
Meanwhile the collars add another dimension to what was already a wonderful 
study opportunity. Not only can you observe behavior up close throughout the 
year, now you can get to know individual birds and some of the geese they spend 
time with. Some pairs have both members collared, and some of these pairs have 
young while others seem not to, but I imagine there could have been many young 
losing track of their parents during the massive round-up and banding & 
collaring operation. 


Today the collared geese and banded young (with many non-collared adults) 
appeared to be all in the part of Stewart Park and Newman Golf Course closest 
to Fall Creek. The only other geese I saw today were a group of 35 adults (none 
with collars, no young) on Cayuga Inlet by the south end of the bike path along 
Floral Avenue, and a single non-collared adult on Cayuga Lake near East Shore 
Park.

[cayugabirds-l] Henslow's and Grasshopper sparrows

[Jay McGowan]

The Henslow's field on the west side of West King Road continues to be
productive. The night before last, Marshall Iliff had *3* different singing
HENSLOW'S SPARROWS there, and we heard at least two tonight, as well as a
very distant GRASSHOPPER SPARROW!

[cayugabirds-l] Woodcock on Sherwood platform at Cornell Lab of O

[Lee Ann van Leer]

I'm leading a bird walk and we found it on Wilson Trail north and it keeps 
walking in front of us and is now on Sherwood Platform. It did the woodcock 
bobbing 'dance' for us! Quite a treat. 4 stinkin' cute Bluejay fledglings being 
fed at Fuller wetlands on same trail.
