That's Ted Floyd in the green jacket...we had just arrived about 15 minutes prior and there were already people waiting, 45 minutes before start time! Ted and I spend an enjoyable morning in Gregory Canyon in Boulder Mountain Park...
I needed a few passerines for my life list, of which I checked off four: Mountain Chickadee, Pygmy Nuthatch, Canyon Wren and American Dipper!!
Here are a few birds that I was able to photograph during my weekend visit:
|Adult type LBBG with Herring and Ring-billed. Teller Lake, CO. 03 Feb 2013.|
This molt timing generated some discussion on the Facebook Group "North American Gulls". There are no documented graellsii individuals that have been known to still be growing their outer primaries in February. There are such records of intermedius, fuscus and heuglini birds and is likely present in the paler subspecies grarellsii in the northwest of Africa.
|Adult Thayer's feeding on fish carcass. Teller Lake is a small lake that was drained and hence many dead fish made the gulls happy.|
