Behavior
Introduction
Little information. Like other species of swift, Great Dusky Swift captures insects in flight (Sick 1993), and spends most of its time in flight, landing only to roost or at the nest. This species has a rather fluttery flight (Chantler 2000).
Territoriality
No information found, but since they are colonial breeders who breed together under waterfalls, they likely would only be territorial in the area most immediately around their nest (a small area).
Sexual Behavior
Undescribed, but presumably is at least socially monogamous.
Social and interspecific behavior
Regularly congregate and roost in flocks of hundreds at waterfalls (Pacheco and Olmost 2005). Great Dusky Swift often forages in flocks, which may associate with White-collared Swift (Streptoprocne zonaris) (Chantler 2000).
Predation
No reports of predation on Great Dusky Swift?
