occurs (regularly, as a native taxon) in multiple nations, but breeds in a single nation

United States

Origin: Native

Regularity: Regularly occurring

Currently: Present

Confidence: Confident

Type of Residency: Year-round

Global Range: Breeding range encompasses coastal Washington, Oregon, and California (Lowther et al. 1999).

Habitat Type: Terrestrial

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.

United States

Rounded National Status Rank: N2 - Imperiled

Rounded Global Status Rank: T3 - Vulnerable

Reasons: Has suffered a long-term decline in California due to habitat loss and cowbird parisitism. Status in northern portion of range unclear.

Global Short Term Trend: Unknown

Global Long Term Trend: Decline of 30-70%

Comments: Once a common to locally abundant summer resident in riparian areas in coastal California. For example, there are no recent breeding records for San Francisco where it previously was common. Breeding populations in Marin County have declined, but the species is still common in Santa Cruz County. The yellow warbler has declined significantly as a breeding bird in the coastal lowlands of southern California.

Comments: Loss of habitat in riparian corridors and brood parasitism by cowbirds (Ehrlich et al. 1992).
