Distribution
Breeding Alaska and southern Canada southward throughout the USA through Mexico and Central America to Costa Rica; wintering to Panama.
Taxonomy
Northern Rough-winged Swallow was in the past considered conspecific with Southern Rough-winged Swallow. Subspecies S. s. ridgwayi and S. s. stuarti recognized by some authors (Handbook of Birds of the World) as full species, Yucatan Rough-winged Swallow or Ridgway's Rough-winged Swallow.
Subspecies
This is a polytypic species with six currently recognized subspecies[1].
- S. s. serripennis:
- Breeds from southeastern Alaska east to southern Quebec, south to central California and Florida; winters from Mexico and Florida south to central Panama.
- S. s. psammochrous:
- Breeds from southwestern United States (southern California east to southeastern Texas) and northern Baja California south to southwestern Mexico and perhaps El Salvador; winters from southernmost United States south to Panama, although southernmost breeding populations possibly resident.
- S. s. fulvipennis:
- Breeds southern Mexico (except Yucatán Peninsula), north to central Veracruz, and south to central Costa Rica; mainly resident, but some migrate south to central Panama.
- S. s. burleighi:
- S. s. ridgwayi:
- Resident in the northern Yucatán Peninsula (southeastern Mexico in northern Campeche, Yucatán, and central Quintana Roo)
- S. s. stuarti:
- Resident in southern Mexico (southern Veracruz, northern Oaxaca, and Chiapas), northern Guatemala, and northern Belize
Habitat
Streams, lakes and river banks.
Behaviour
Breeding
Nests in cavities near water, usually a burrow in dirt and 4-8 eggs are laid. Eggs are incubated by the female for 13 days, with another 20 days until fledging.
