Tepui Swift Streptoprocne phelpsi

Large, dark swift of tepui highlands. Note generally dark appearance, broad wings, and forked tail. If seen in good light, chestnut collar of adult is diagnostic; otherwise this species may be difficult to distinguish from other large swifts, especially at a distance. Found around the tepuis and down to at least 400 meters in the surrounding region. Forages high for insects, often with other swifts; may descend to just above treetop level to feed on swarms of emerging winged ants and termites. In poor light, most similar to White-chinned Swift but has more deeply forked tail.
