Icterus cucullatus
Conservation status | Declined sharply in southern Texas in recent decades, perhaps owing to cowbird parasitism. May be making a slight comeback in that area. Still fairly common farther west. |
---|---|
Family | Blackbirds and Orioles |
Habitat | Open woods, shade trees, palms. Breeds in groves of trees (such as cottonwood, walnut, sycamore) along streams and in canyons, and in open woods in lowlands. Often common in suburbs and city parks. Especially favors palm trees, and will nest in isolated groups of palms even in cities. |
Forages rather slowly and deliberately in trees and large shrubs, gleaning insects from among foliage or feeding on berries. Regularly probes in flowers for nectar and probably takes insects there as well. A common visitor to hummingbird feeders.
4, sometimes 3-5. Whitish, irregularly blotched with brown, lavender, and gray. Incubation is by female, about 12-14 days. Bronzed Cowbirds very frequently lay eggs in nests of this species. Young: Fed by both parents. Leave nest about 14 days after hatching. 2 broods per year, sometimes 3.
Fed by both parents. Leave nest about 14 days after hatching. 2 broods per year, sometimes 3.
Includes insects, berries, nectar. Feeds on a variety of insects. May especially favor caterpillars, also eats beetles, wasps, ants, and many others. Feeds on many wild berries, and sometimes on cultivated fruit. Takes nectar from flowers, and will come to feeders to drink sugar-water.
In courtship, male moves around female, posturing with deep bows and then pointing bill straight up while singing softly. Female may respond with similar posturing. Nest: Often placed in palm or large yucca, sewn to underside of large overhanging leaf; usually 10-50' above ground, but can be lower. Sometimes placed under banana leaf, in clump of mistletoe or Spanish moss, or suspended from branch of deciduous tree. Nest is a woven hanging pouch of grass and plant fibers, lined with plant down, hair, feathers. Female builds nest, but male may help bring material.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

The documentary “Birders” showcases the spectacle of fall migration while exploring the concerns of conservationists on both sides of the Rio Grande.
The delicate-looking structures are stronger than they seem, and come in a variety of shapes and materials.
