Carolinabirders,
I just added the observers' description and a summary of opinions on the
hummingbird photos at: http://www.duke.edu/~cwcook/winhum.html
Thanks for your help - so far I've received 30 opinions from the 460 people
that visited the page:
Calliope: 14.5
Rufous, Allen's, or Rufous/Allen's: 14
Ruby-throated: 1
Costa's: 0.5
I wanted to see if a consensus could be reached from the physical evidence
(photos), but it appears not! This is apparently a good illustration of how
tricky identification of female/immature hummingbirds can be.
Opinions based on the photos are posted at
http://www.duke.edu/~cwcook/winhumo.html with my own take at the end, though
I am a little biased since I actually saw the bird. One thing that misled a
lot of people is the apparent patch of gorget feathers in the two lower left
photos. This is an artifact of feather arrangement. Sorry, I didn't
realize these two photos would be so misleading when I selected them. This
bird had no colored gorget feathers, just a pattern of pale brown spotting.
Please let me know if you would like to add a new opinion or revise your old
opinion based on the new information.
Thanks,
Will
