Range

The Fork-tailed Palm Swift, Tachornis squamata, is a resident breeding bird from Colombia, Venezuela, the Guianas and Trinidad south to northeastern Peru and Brazil. In Suriname confined to the savanna areas, does not occur in the coastal plane

Habitat

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

Reproduction

It 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.

Feeding habits

Fork-tailed Palm Swift 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.

Conservation

This species has a large range, with an estimated global extent of occurrence of 9,500,000 km2. The global population size has not been quantified, but it is believed to be large as the species is described as ‘common’ in at least parts of its range (Stotz et al. 1996). Global population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
