Багамская ласточка Tachycineta cyaneoviridis

An elegant aerial hunter most often found in pine woodlands, but also seen in towns and over fields. Note the long forked tail, green to blue-green upperparts, and white underparts. Tree Swallows are similarly colored, but have a shorter, notched tail. Tree Swallows also have entirely dusky underwings unlike Bahama Swallows which have white armpits. Calls include a slightly squeaky “chet” or “chet-chet” and a thin “tsi-tsip.” Song is a beautiful liquid jumble of rich notes.
