I've been compiling a lifelist since 2006, and sometime after that point (when I got a camera) I started keeping a lifephotos folder as well. It took many, many sightings, but I finally got a good photo of a Brown Creeper for my file:
What a sweet little bird! He's up here in the frozen north, though I would think he'd have headed south by now. The weather's awfully chilly today (24 degrees, with gusty winds up to 28 mph; windchill in the low teens), so I hope he's okay.
