BIRD OF THE WEEK
YELLOW WARBLER
SCIENTIFIC NAME: Setophaga petechia
POPULATION: 92 million
TREND: Stable
HABITAT: Breeds in wet woods, thickets, and riparian areas; winters in open woodlands, on farms and gardens with scattered trees, and in mangrove forests.
The Yellow Warbler is the most widespread American wood-warbler. It nests from Alaska to northern South America (including the Galapágos Islands), and in parts of the Caribbean as well, and winters as far south as Peru.
One of the Yellow Warbler’s calls, a repeated seet, serves specifically as a Brown-headed Cowbird alert. When a female hears another bird make this call, she rushes back to her nest to prevent the cowbird, a notorious nest parasite, from laying eggs there.
