Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No 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.

After the breeding season (August-September) some adult and subadult males move northward and overwinter as far north as British Columbia; return south March-May. Males from Baja California rookeries arrive in southern California in December-January (Reeves et al. 1992). Migratory status of females and young unclear.
