Ecology & Habitat

Description

An 18-cm-long bird with a crest, yellow-tipped tail, silky plumage, and waxy red tips on the secondaries; brown above; pale yellow belly; white undertail coverts; juveniles has dark streaking (NGS 1983).

Diagnostic Characteristics

Differs from the bohemian waxwing in smaller size, browner plumage (vs. grayish), white undertail coverts (vs. cinnamon), and lack of white and yellow markings in wing.

Habitat

A wide variety of open woodland types, either deciduous or coniferous, forest edge, second growth, parks, orchards and gardens; in migration and winter occurring wherever there are trees (AOU 1983).

Nests in tree or shrub, 2-15 m above ground, in fork or on outer horizontal limb (Terres 1980).

Ecology

Usually travels in small groups or flocks; winter flocks may number in thousands.

Reproduction

Breeding season variable. Female incubates 3-5, sometimes 6, eggs for 12-16 days. Young are tended by both adults, leave nest at 14-18 days. Sometimes nests in small colonies of up to 12 pairs.
