Add to My List Check Off

White-Throated Swift are small, with a black back, wings, and tail, a white throat, belly, and sides behind the wings. They have a cylindrical body, with long, pointed, swept back wings. Diet and behavioral habits: A fairly common year-round resident, the White-throated Swift is seen all around Balboa Park from the Cabrillo Bridge to the Florida Canyon, since the 1940’s. They are very social birds, often sleeping in roosts of hundreds of birds. Feeding on a wide variety of flying insects, including flies, beetles, true bugs, wasps, and on winged adult ants. Nesting habits: Many details of nesting remain poorly known, partly because the nest sites are so inaccessible. The nest site of the White-Throated Swift is usually in narrow vertical crevice in buildings or cliffs. Nesting sites may be used for many years. The nest itself is shaped like shallow half saucer; made of feathers, weeds, grasses, glued together and to wall of crevice with the birds' saliva.
