Description:

The swallow displayed pale buffy cheeks and throat contrasting w/ a dark crown and forehead, a buffy collar was apparent at rest, an overall whitish underside w/ grayer sides and flanks, a buffy-orange rump, noticeably rounded wingtips and a relatively short square tail.

Voice:

N/A

Similar species:

-separated from TRSW in flight by slightly smaller size and rounded wing shape, which allow for a conspicuously different flight style (more swift-like) than TRSW

 

-the 'southwestern' melanogaster ssp. of CLSW was eliminated by the constrasting pale buffy cheeks/throat and dark crown/forehead, which is lacking in this sp. altogether

-the nominate 'eastern' ssp. of CLSW was eliminated by the absence of white on the forehead, also lacking the contrasting head coloration demonstrated by CASW

-the nominate 'Caribbean' ssp. of CASW was eliminated by the pale, unmarked sides and flanks (otherwise rufous in this ssp.) and pale tawny rump, which is reddish-brown in this ssp.
