Little information. Biscutate Swifts are aerial insectivores, and often forage around waterfalls. Gregarious, these swifts often fly out of roost caves in flocks, and return to roosts in the evening to spend the night (Pichorim and Filho 2010).
Breeds in large colonies in caverns, so apparently little individual territoriality.
Little known. Courtship displays, if any, apparently undescribed. Presumably is at least socially monogamous.
Social and interspecific behavior
Biscutate Swift is gregarious, usually foraging in single species flocks, which sometimes associate with flocks of White-collared Swift (Streptoprocne zonaris) (Belton 1984, Kirwan 2007).
Common Gray Four-eyed Opossums (Philander opposum) are a suspected predator on eggs of Biscutate Swift (Pichorim 2002).
