Подробности наблюдения
Careful comparison made with nearby Vaux’s Swift’s. The giss of this bird was just different from the other Swift’s. Slightly larger, longer wings, slower wingbeat. Body seemed longer behind the wings than Vaux's. Did not vocalize. Photos show wings to be somewhat ragged. Photos also show the "bulge" at the secondaries. We were able to pick the bird out repeatedly from the flock.
