The Lesser swallow-tailed swift or cayenne swift (Panyptila cayennensis), is a species of resident breeding swift from southern Mexico and Tobago south to Ecuador, eastern Peru and Brazil. This small swift is found in range of habitats including forest clearings, more open woodland, and cultivation. The nest is tubular, wider at the top, and with the entrance at its base. It is made of plant material and attached to a branch or a vertical surface. In the latter case, the entire length is fixed to the wall or trunk. Two or three white eggs are laid on a shelf in the upper part of the nest, and incubated by both parents.
