About the Mangrove Swallow
The mangrove swallow is a passerine bird in the swallow family that breeds in coastal regions from Mexico through Central America to Panama. It has blue-green upperparts, blackish flight feathers, a white rump, a black tail, and white underparts. It can be identified by the supraloral white streak, the white line near its eye, which only occurs in two other species of Tachycineta: the violet-green swallow and the white-rumped swallow. The sexes, although similar in plumage, differ slightly in size. The juveniles have grey-brown upperparts and white-washed underparts. This swallow's song is generally described as a soft trilling, with a rolled jeerrt call, and a sharp alarm note.
