Above is the first of what I hope continues to be a semi-regular set of “mystery bird quizzes” here on Nemesis Bird. This photo shows three gray and white birds landing. The was taken by me, somewhere in Pennsylvania on October 25th, 2009. If you would like to participate in the quiz, please leave your answer as a comment on this post! Once quite a few guesses have been entered, I will post an answer with a full explaination of what the birds are and why. Have fun!
