black and white warbler

We were stalking golden-cheeked warblers today. I've been trying to get a picture of one for several years. This one fooled me - I thought it was a female golden cheek, but it's a male black and white warbler. Maybe next year! (The golden-cheeked warblers only come to Texas for about three weeks to breed, and then return to Mexico and Central America shortly after the babies fledge. There are thought to be fewer than 4,000 remaining.)
