Nominate race partial migrant. Present British Columbia in far N of range, early Apr to late Sept, most departing
from late Aug. Migrant Californian population present mid-Mar to mid-Oct. Winters S California and Nevada
where absent from coldest areas; it has been suggested that predominance of coastal winter records in Baja
California suggests at least limited seasonal altitudinal movements. Most winter farther S, some as far as
Honduras. Migrates in flocks, up to 50. Rarely recorded SE Farallon Is, 42 km W of Francico, during Apr and
mid-late Oct. Race nigrior resident. Data from Belize unconfirmed. (del Hoyo J, Elliott A,
