A tiny dark swift with a long, slender, pointed tail. Restricted to the Maracaibo basin of Venezuela, barely slipping over the border into Colombia in Norte de Santander. In flight note the dark body with pale gray throat and belly. Similar to Fork-tailed Palm-Swift, but Pygmy Swift is much smaller and has darker underparts. Usually in groups flying in circles at low levels close to grasslands, open areas, towns, always near palm trees.
