Colombia Tanagers courtesy of Richard Crossley

Richard is still hard at work on the upcoming Western version of The Crossley ID Guide. In the meantime, enjoy his video of Colombia Tanagers and other Western species coming in to feed on bananas. Listen carefully as he IDs a young male that his companions previously thought was a female. This type of ID — using transitional plumage — is where The Crossley ID Guide is absolutely invaluable. Richard’s photo spreads include more plumages, more specimens, more of everything to make difficult IDs easier.

Also, if you are a fan of NPR’s Science Friday, tune in this week to hear Richard discuss the Christmas Bird Count.
