Range DescriptionCollocalia elaphra is endemic to the Seychelles and ranges over the islands of MahÃ©, Praslin and La Digue, with one known breeding site on each island. A colony on FÃ©licitÃ© has disappeared, as has one on MahÃ© (; Watson 1984). The La Digue cave held 35-45 nests in 1996-1997 (Rocamora 1997a), but as numbers have fluctuated in the past (MacDonald 1978; Watson 1984) it is unclear whether there is a continuing decline at this site. In the Praslin colony, 56 nests and 152 birds were estimated in 1977 (MacDonald 1978), with 60-80 nests from 1980 onwards (Rocamora 1997a; Watson 1984). Studies in 1996-1997 estimated the total population at 2,500-3,000 individuals (Rocamora 1997a).
