In patch birding, it's all relative. You're not after huge numbers, you're not expecting rarities. Instead, it's about really knowing a place, and learning its rhythms. When you're stuck with a patch long enough, you learn to love it no matter how few birds there are.
And there aren't a lot of birds on my patch, Yards Park along the Anacostia River in DC. It's where I walk my dog most every day after work. Despite running along a big ol' river and featuring at least some greenery, I've only managed 62 species despite visiting a few times a week for a year and a half. I dunno, that's not a tiny number, but it's less than I could get on a decent spring day at a park just up the river. (Also, it's enough to make me the hotspot leader by about 30 species).
But it's what I've got, you know? And I love it. I especially love it on days like yesterday, a gray and dreary afternoon where I somehow beat my previous dog walking record and saw 17 different species. Check out that list! The clincher was a solo mourning dove that cruised overhead when I was back on South Capitol Street, almost home. My dog had no idea what I was yelling about.
Anyway, in honor of my record-breaking afternoon I made a quick. annotated bird finding guide to Yards Park. It's oriented South to North, which is the way I walk it, but it's a little confusing that way. It's displaying small, but you can click to enlarge. Or you can just not do that, and go on with your life.
