| Although the breeding ranges of Archilochus alexandri (Blackchinned
Hummingbird) and Archilochus colubris (Ruby-throated Hummingbird)
are narrowly parapatric in central Texas and central and southern
Oklahoma, there have been few reports of hybridization in the literature and
no well-documented hybrid specimens. Here we provide a comprehensive
assessment of two male hybrids collected, respectively, in Grayson County,
Texas, and East Baton Rouge Parish, Louisiana. As has been the pattern in
other hummingbird hybrids, both specimens exhibit a blended mosaic of
plumage characters of the parental species. Sequence for mitochondrial
cytochrome c oxidase subunit 1 (CO1) for the hybrid specimen from East
Baton Rouge Parish (LSU 182,831) confirms A. colubris as the female parent. | |
