Fork-tailed palm-swift

The fork-tailed palm swift or Neotropical palm swift (Tachornis squamata) is a swift native to tropical South America (from Colombia, Venezuela, the Guianas south to northeastern Peru and Brazil) and Trinidad in the Caribbean.

Taxonomy

Despite its shape and association with palms, it is in a different genus to the Asian and African palm swifts.

Description

The fork-tailed palm swift is a slender, narrow-winged species, 13.2 cm long, with a long forked tail, and weighs 11 g. The call is a buzzed djjjjjj, like an insect. The nominate western form T. s. squamata has black-brown upperparts with a slight greenish gloss. The underparts are a paler brown with a white throat and central underbody. The eastern race T. s. semota of Trinidad, the Guianas and central and eastern Brazil is much darker, almost steel-black above and darker brown below. Juveniles are very similar, but have buff fringes to the upperparts and head in fresh plumage.

Distribution and habitat

This small bird is found locally in marshy habitats, or sometimes open forest, usually near Moriche Palms.

Behaviour and ecology

Breeding

The fork-tailed palm swift builds a C-shaped nest of feathers, saliva and plant material on the inside of the dead leaf of a Moriche Palm. Three white eggs are laid in the depression of the C, and incubated for 21 days to hatching.

Food and feeding

It feeds in low flight on flying insects. It normally stays at less than 10 m above the ground. It normally occurs in small groups of up to 30 birds.
