觀察細節

First heard at 6:16 when I was passing under the ash tree. Used a call recording to see if it would respond, which it quickly did and it came pretty close. Distinguished from blue gray gnatcatcher (western) mainly by range and color of the outer tail feathers, calls may have been a bit too high pitched for (western) but can be hard to judge. Central Texas is within the native range of the eastern subspecies/subspecies group and while it is possible for western birds to migrate through I don’t know how frequently they may occur in this area and I am not sure if it is too early or not for a (western) to occur here. Blue gray gnatcatcher (Western) would have black at the base of the outer tail feathers, while eastern birds have white outer tail feathers. Bluish grey above, white below, black and white tail with no black on the outer tail feathers.
