Distribution

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:
Resident in the southern Yucatán Peninsula (northern Guatemala and Belize)
  • 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
