Avian Quiz – March 11, 2011
As I’ve mentioned before, clues for these quizzes are taken from bird guides and other resources. The single resource for today’s quiz is a book I just purchased. It is not a new book, about 6 years old.
Today we are looking at two species that can be difficult to separate under typical field conditions. I have encountered this situation only one time in my birding experience. The people with whom I was birding thought this ID was a no-brainer, based solely on their familiarity with the location. We’re not talking habitat, we’re talking geographic location here. I tried on a purist attitude and chose not to ID the species.
To answer this quiz, please do NOT indicate the species of either bird. Instead, indicate a location where this difficult ID occurs.
Extra Credit: Tell us all how you separate these two species (I need the help!).
Here are the clues that I have gleaned from this new book:
1. This identification is usually a no-brainer. The only time it is difficult is based on location or during an irruption year.
2. Size is interesting, but isn’t definitive.
3. Facial characteristics are interesting, but aren’t definitive.
4. Behavior is interesting, but won’t help.
5. Song is interesting, but isn’t definitive.
6. Wing coloration while sitting will help. But not while flying. Think “white”.
7. Call will help.
8. Beware of hybrids.
As always, unless otherwise indicated, all species are typical ABA species.
