Taxonomic Swap 118875 (הועלה ב 2022-12-20)

In accord with AOS-SACC (Chesser et al. 2022), each of the two monotypic groups is recognized as a species: the group Streamertail (Red-billed) Trochilus polytmus polytmus becomes Red-billed Streamertail Trochilus polytmus; and the group Streamertail (Black-billed) Trochilus polytmus scitulus becomes Black-billed Streamertail Trochilus scitulus. There is only an extremely narrow, and apparently stable, hybrid zone between these two taxa (Gill et al. 1973, Graves 2015); there are exceptionally steep clines in bill color and genetics (Judy 2018); and vocal and display differences between them have been reported (Schuchmann 1977, 1979). Revise the range of Red-billed Streamertail from "Jamaica (except range of scitulus)" to "Jamaica (except in the far east)".
