I'm sort of new to this birdwatching thing, and have seen a pair of these very small, delicate birds hopping around my salvia and perching on my tomato plants the past 2 days. He looks smooth-headed in this pic, but at times fluffs out to almost have a little crest. I checked my central texas guide book, and am pretty sure he's a Lincoln's Sparrow.

Sorry if it seems obvious to you old hands, but I'm not good at this yet (and have a crappy camera!).
