The Golden-crowned Warbler (Basileuterus culicivorus) is a small New World warbler.

Distribution and habitat[edit]

It breeds from Mexico and south through Central America to northeastern Argentina and Uruguay, and on Trinidad. It is a species mainly of lowland forests.

Description[edit]

The Golden-crowned Warbler is 12.7 cm (5.0 in) long and weighs 10 g (0.35 oz). It has grey-green upperparts and bright yellow underparts. The head is grey with a black-bordered yellow crown stripe, a yellow or white supercilium and a black eyestripe. Sexes are similar, but the immature Golden-crowned Warbler is duller, browner, and lacks the head pattern other than the eyestripe.

Taxonomy[edit]

Golden-crowned Warbler has 13 geographical races, which fall into three groups. The Central American culicivorus group ("Stripe-crowned Warbler")[clarification needed] is essentially as described above, the southwestern cabanisi group ("Cabanis's Warbler") has grey upperparts and a white supercilium, and the aureocapillus group ("Golden-crowned Warbler") of the southeast has a white supercilum and orange-rufous crown stripe. The three groups are sometimes considered to be different species.

Behaviour[edit]

These birds feed on insects and spiders. The song is a high thin pit-seet-seet-seet-seet, and the call is a sharp tsip. It lays two to four rufous-spotted white eggs in a domed nest in a bank, often by a forest path, or under leaves on the forest floor. Parent birds will feign injury to distract potential nest predators.
