There's not been any Backyard Science diary posts for a while. But, I know you are still out there. Until the next one, here's a place to toss in your two cents worth.
Member janislav wrote me this week about seeing 'unusual looking' sparrows at his feeders in eastern IA. Turns out they were Eurasian Tree Sparrows. http://www.allaboutbirds.org/...
Your turn...
By the way, if someone has a diary to post, go ahead as you had planned.
