Habitat: This species can be found across the country and in different types of habitats. Distribution: Mexico to northern Argentina and southern Brazil. Also found in the Greater Antilles. Natural History Notes: White-collareds are almost always observed in flocks, often with other swifts. Like all swifts, they are insectivors, catching insects in their gaping mouths during rapid flight. White-collareds are particularly fast-flying and cover great distances in their daily foraging. When they are chasing each other or near their nesting colonies they make loud hissing screeches and chittering calls. Nests are generally inaccessible, on damp cave walls or rock faces, often behind waterfalls. Characteristics: The total length of this species varies between 19.05 cm and 21.59 cm (measured from tip of bill to end of tail). The animal has a large black swift with a white collar that encircles the neck. The tail has a fork shape. Notes: Conservation status according to IUCN 2008 Red list: Least Concern (LC). It is a resident species.
