Hirundo serripennis

Audubon

, 1838,

Charleston, South Carolina, USA

.

Usually considered conspecific with S. ridgwayi (which see). Formerly treated as conspecific with S. ruficollis (which see). Sometimes treated as monotypic: races intergrade and borders between them (and degree of overlap) uncertain, also N–S cline in coloration, and there is a tendency for paler forms in SW USA and NW Mexico, also size increases N to S and wing longer towards NW; fulvipennis may not be separable. Race burleighi sometimes included in S. ridgwayi. Proposed race aphracta (W Great Basin region of USA), supposedly dark above and with greyer throat, appears undiagnosable. Four subspecies tentatively recognized.
