Yellow Warbler

Dendroica petechia

Although many warblers are yellow, the Yellow Warbler is the most extensively yellow of any species. This widespread species of willows and mangroves is the only warbler with yellow tail spots.

Cool Facts

The Sibley Field Guide to Birds of Western North America by David Allen Sibley
  • In addition to the migratory form of the Yellow Warbler that breeds in North America, several other resident forms can be found in Mexico, Central America, and the Caribbean. Males in these populations can have chestnut caps or even chestnut covering the entire head.
  • The nests of the Yellow Warbler are frequently parasitized by the Brown-headed Cowbird. The warbler often builds a new nest directly on top of the parasitized one, sometimes resulting in nests with up to six tiers.
  • Recent DNA-based studies indicate that the Chestnut-sided Warbler is the closest relative of the Yellow Warbler. Both sing similarly phrased songs, and Yellow Warblers regularly sing songs nearly identical to those of the Chestnut-sided Warbler.
  • A group of yellow warblers are collectively known as a "stream", "sweetness", and "trepidation" of warblers.

Conservation Status

Widespread and abundant; no clear continentwide trend in populations. Vulnerable in western areas where riparian habitats are affected by intense grazing and development.
