观察细节
Found a bird that seemed to be a Dusky between lanes 25-26 around 11:30am, foraging actively about 10-15' up. Appearance similar to Hammond's but I followed this bird around until it called, which was clearly a "whit" and not a "pip". Lower mandible seems to be almost entirely orange/yellow, darkening slightly towards the tip (not consistent with Hammond's), but the primary projection looks to be too long for Dusky. Head shape, bill length, and behavior aren't consistent with Gray (lots of tail flicking, no tail dropping). Coloration doesn't seem striking enough for Least, and I'm not about to call this a Pine, so I'm not sure what it is. Photos.
