Michael and I spent 3 weeks birding in Costa Rica last month, partly on our own at highly recommended Bosque del Rio Tigre lodge and at San Vito, near Panama, and partly on a wonderful Road Scholar birding trip. Our local guides saw and/or heard an incredible 445 species, although we wouldn't count that many, if we were listers. This photo of a scaup female was taken by Michael, shooting into late afternoon light from a boat at quite a distance. It was with a group of Blue-winged Teal. It looks like a Lesser Scaup by head shape, but does the amount of white near the bill look more like a Greater Scaup? Lesser Scaup are seen in Costa Rica, but Greater Scaup have only been reported a few times. Any thoughts? The sighting was too far off for the guide to make a definitive ID at the time. We have only the one photo and did not see the bird fly. http://s1168.photobucket.com/user/krallfamily/media/imagejpg1_zpsf5227375.jpg.html Kathy and Mike Krall Sent from my iPad
