Pine Warblers

This winter I've had Pine Warblers at my feeders. In the past, I've seen them in my yard, but never at my feeders. I've really enjoyed having them and hope they stick around into spring. Most of the time, I'll see a male and female, but occasionally I'll see four of them at a time. They are already calling quite a bit, so it's pretty easy to know when they're around. Here's a picture of one that I got on Monday. They're relatively unafraid of me. I was maybe 12 feet from the feeder when I took this picture. He watched me, but seemed unconcerned that I was standing there.
