More birds appearing in my neighborhood

As I've mentioned previously, I live in a neighborhood in the middle of a big Midwestern city, and I have about as bird-unfriendly a yard you can have without it being bare concrete. However, I am fortunate enough to live between two wooded ravines that are accessible by pedestrians - Glen Echo and Walhalla Ravines. Lately, I've been spending more time in Walhalla Ravine since I've added it to the dog walking route. I'll take Henry, our pug mix, for his walk and bring along my spare binoculars. He gets to sniff all the dead leaves he wants while I look at birds. It's a win-win situation.

Anyway, I started keeping track of the birds I see in the neighborhood between the two ravines. I added three new birds yesterday, Northern Flicker, Yellow-bellied Sapsucker, and Eastern Phoebe. The phoebe was a bird I had expected to see before now, since the Walhalla ravine seems like great habitat for them, but I'm just glad to have it. Last weekend I saw a Winter Wren in the ravine, so now I'm hoping for Louisiana Waterthrush when I take Henry for an early morning walk tomorrow. I haven't been in the ravine in the morning yet, usually I take the dog out after work.
