12 cm (4¾ in)
Male: Face, throat, and underparts yellow with slightly duskier auriculars and glossy black cap. Nape and upperparts yellow-olive, wings and tail darker.
Female: Crown olive to mostly black.
Distribution
Breeds in North America from Alaska throughout most of Canada east to Newfoundland south to northern New York and northern New England in the east; in the west found in coastal mountains south to southern California and in the Rocky Mountain region. In migration found throughout the United States and Canada. Winters Mexico south to western Panama.
Accidental vagrant to Greenland (1 record) and Great Britain (1 record).
Taxonomy
Formerly placed in genus Wilsonia.
Subspecies
There are 3 subspecies1:
- C. p. chryseola - breeds along the pacific coast from British Columbia south to southern California
- C. p. pileolata - breeds from Alaska south to interior west
- C. p. pusilla - breeds from Northwest Territories and Saskatchewan east throughout eastern range
Recent molecular results indicate that these might comprise two species, with C. p. pileolata including chryseola becoming C. pileolata (Pileolated Warbler?)[3][6].
Habitat
Thickets and brush, especially near water. They breed in a variety of woodlands, especially conifererous and mixed deciduous/coniferous and woods on boggy ground.
Behaviour
Diet
Their diet consists mostly of insects and spiders. With the addition of honeydew and berries when available.
Breeding
Their breeding season runs from April to July. Some populations may have a second brood.
Vocalisation
Song: a rapid series of 10-15 short, whistled notes chchchchchchchch with sharp, chattery quality; last few notes usually lower and faster, generally downslurred, sometimes two-syllable.
Listen to a song clip (subspecies C. p. chryseola)
