White-winged Black-tyrant male
OK, so maybe it's not the nicest habitat shot. But I sure got the bird! This was actually out on a hiking trail surrounded by natural habitat, but there was an electrical substation enclosure here, and the bird picked the fence to perch on (maybe because it provided a little clearing). A white wing patch (the tip of the white wing band) was occasionally visible with the bird perched, but isn't showing here.
