Cliff and Cave Swallows are closely related. The Cliff Swallow currently is widely distributed over the region, whereas the Cave Swallow reaches west and north to the Guadalupe Mountains region. Preferred nesting sites make both of these species liable to ending up in cave fill. In the mid-sixties, Dry Cave had a few remnants of nests in the Entrance Chamber, but not enough remained to determine the species involved. The Cave Swallow currently nests in Sierra Diablo Cave; preservational data suggest pre-Holocene occurrences, also.
