Collocalia brevirostris vulcanorum

west Java


Previously was often treated as a race of A. brevirostris, but differs in its dark underparts (2); indistinct grey rump (2); sparse white rami in plumage compared with other taxa in brevirostris (1); slightly smaller size with shallower tail fork (from incomplete published data#R) (allow 1); sexual dimorphism in tarsal feathering (females with, males without) (allow 2); possibly different vocalizations (not reported for other taxa, including capacity to echolocate) (no score until evidence on other taxa assembled, but potentially conclusive). Monotypic.
