There is little information on the behavior of Tepui Swift. These swifts are aerial insectivores, spending most of the day in continuous flight, capturing insects on the wing. The flight often is quite high and straight when engaging in long distance commutes (Hilty 2003); when foraging, however, may fly low over treetops or grassland (Gilliard 1941, Barrowclough et al. 1997), "wheeling rapidly back and forth for several min[utes] in a small area before moving on" (Hilty 2003). During foraging flights, flurries of stiff, rapid wingbeats are interspersed with glides and swerving arcs, in which the wings are held down sharply below horizontal (Hilty 2003). Tepui Swifts roost on cliffs near water (Hilty 2003).
