Typical Environment
Occurs in southeastern and south-central Brazil, eastern Bolivia, and northern Argentina, with possible occurrence in Paraguay. Most frequent in and around the Atlantic Forest, serras, and escarpments where suitable cliffs and waterfalls are available for roosting and nesting. It forages widely over forested landscapes, river valleys, and open country, often far from the roost sites. The species can form mixed flocks with other large swifts when insect swarms are abundant.

A large swift of the Atlantic Forest and adjacent highlands, it is often seen in fast-flying flocks high over valleys and ridges. The name “biscutate” refers to the broken white collar that appears as two separate pale patches on the sides of the breast, helping distinguish it from the White-collared Swift. It frequently roosts and nests on damp cliff ledges, including behind waterfalls. These colonies can be quite noisy at dawn and dusk.
