Pygochelidon

Pygochelidon is a genus of birds in the swallow family, Hirundinidae. The genus was introduced by the French zoologist René-Primevère Lesson in 1830. The name Pygochelidon is derived from the Greek words "pygos," meaning "tail," and "cheilos," meaning "lip," referring to the distinctive forked tail of these birds. The genus includes two species: the Fork-tailed Palm Swift (Pygochelidon cyanoleuca) and the Fork-tailed Swift (Pygochelidon forktail). Both species are found in the Americas, with the Fork-tailed Palm Swift inhabiting the Caribbean and Central America, and the Fork-tailed Swift ranging from southern Mexico to northern Argentina. These birds are known for their forked tails, which are used for aerial displays and courtship rituals. They are also notable for their long, slender bills and their ability to hover in mid-air. The Fork-tailed Palm Swift is particularly adapted to life in palm trees, using their long, curved claws to perch on the trunks and branches. The Fork-tailed Swift, on the other hand, is more adaptable and can be found in a variety of habitats, including forests, savannas, and urban areas. Both species are migratory, with populations moving to lower latitudes during the winter months. They are generally considered to be of Least Concern by the IUCN, although their populations may be declining due to habitat loss and other factors.
