The Thayer's Gull was still there when I left about 1:05. Thanks, Tom, for posting. We miss you and look forward to your return to the Basin.
I was able to get a few photos that you can see in my eBird checklist at the link below. This is a fairly normal-looking juvenile Thayer's Gull (to the extent such a thing exists). I suspect it would be easier to pass this off as a Herring Gull than an Iceland Gull. When scanning through 1st-year Herring Gulls, look for the paler upperparts and note that the primaries on this bird are dark brown, not black as in Herring Gull. It's a bit more obvious in flight when the paler underwing stands out, as does the distinctive upperwing pattern. http://ebird.org/ebird/view/checklist?subID=S9303125 See this story for information on how to embed photos in an eBird checklist: http://ebird.org/content/ebird/news/embed-photos-in-your-checklists Best wishes, Chris Wood eBird & Neotropical Birds Project Leader Cornell Lab of Ornithology, Ithaca, New York http://ebird.org http://neotropical.birds.cornell.edu On Fri, Dec 9, 2011 at 12:54 PM, Tom Johnson <[email protected]> wrote: > Cayugabirders, > Chris Wood reports a juvenile Thayer's Gull at the compost piles on > Stevenson Rd., Dryden. > Good birding, > Tom > > -- > Tom Johnson > Hummelstown, PA > [email protected] > > -- > > Cayugabirds-L List Info: > http://www.NortheastBirding.com/CayugabirdsWELCOME > http://www.NortheastBirding.com/CayugabirdsRULES > http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm > > ARCHIVES: > 1) http://www.mail-archive.com/[email protected]/maillist.html > 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds > 3) http://birdingonthe.net/mailinglists/CAYU.html > > Please submit your observations to eBird: > http://ebird.org/content/ebird/ > > -- -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/[email protected]/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
