Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: Yes. At least some populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Breeding populations in U.S. and Canada make long migrations to Mexico, Central America and Venezuela (Bull and Collins 1993). A few winter irregularly in southern coastal lowlands of California (CDFG 2000). Resident throughout the year in Mexico, Central America, and Venezuela but may make local migrations to lowlands (Stiles and Skutch 1989; Howell and Webb 1995).
In Oregon, some left their nesting areas in late August and early September and were found at large communal roosts sheltering more than 500 swifts; these large roosts were used until mid-September when swifts left the study area (Bull and Blumton 1997).
