觀察細節
Flew overhead as I was walking the creek bed; did not vocalize; Chaetura swifts molting inner primaries. Seen from below so could not determine rump color. Most likely Chimney Swifts as Vaux's has never been documented in Texas. Attached images are of two different birds. One bird appeared to have more tapered wings but both were molting, so difficult to determine true shape.
