So you think you know your birds? Last year Partners in Flight issued their population estimates, most of them based on the Breeding Bird Survey, for most of North Americas land birds. See how many of these ten species you can correctly match with its population estimate. If you have no fear of humiliation post your list to the entire group. Jeff Gibson will buy everyone who gets them all right a beer.

No cheating!
