Northern Rough-winged Swallow photographed in flight by Curtis A. Marantz on 16 December 2021 along the Whitewater River, north end Salton Sea, Riverside County, California.
Podrobnosti k pozorování
Dean spotted this bird flying over the Johnson Street canal where it crossed under the levee road. I heard this bird call once, giving a sputtering "brrrt," but we saw it well. It was a relatively small swallow with a square-tipped tail and broad based wings that tapered to pointed tips. The upperparts were entirely a warm, dark brown and lacking contrast, but the underparts contrasted dingy brownish on the throat, breast, and sides with white on the belly and flanks/ This bird perched briefly atop a nearby snag, but it flew before I could get close enough to get a photo. I did manage to get a few photos of the bird in flight.
