Hooded Oriole Life History

Habitat

Habitat Open WoodlandsHooded Orioles live in open, dry areas in the Southwest with scattered trees including cottonwoods, willows, sycamores, and especially palm trees. They occur farther north than they did in the past as residential and commercial developments began planting more and more palm trees. During the nonbreeding season in Mexico, they also use open areas with scattered trees. Back to top

Food

Food InsectsHooded Orioles search the undersides of leaves for spiders and insects such as ants, beetles, grasshoppers, larvae, and caterpillars. They also eat fruit and take nectar from flowering plants and hummingbird feeders.Back to top

Nesting

Nest Placement

Nest TreeThe female stiches a hanging nest to the undersides of palm, sycamore, or eucalyptus leaves about 20 feet above the ground.

Nest Description

Like other orioles, females weave grass and plant fibers together to form a hanging basket. Female Hooded Orioles stitch the nest to the underside of leaves. Females build these elaborate basket nests in 3 to 6 days. Nests are about 4 inches tall.

Incubation Period:12-14 days

Behavior

Behavior Foliage GleanerHooded Orioles are methodical and acrobatic foragers that hang, often upside down, from leaves and branches in search of food. They tend to forage at low to middle levels in trees and shrubs. When they fly between trees their flight is strong and quick. Unlike other orioles, they tend to sing partially hidden inside trees and shrubs. Sometimes they flick their tail upward while chattering almost incessantly. Males point their bills to the sky and hold a sleek posture while chattering during territorial disputes with other males. During courtship, males flutter their wings as they move from branch to branch, bowing to the female. Back to top

Conservation

Conservation Low ConcernHooded Oriole populations remained stable between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 700,000, with 51% breeding in the U.S., and 98% spending at least part of the year in Mexico. The species rates a 10 out of 20 on the Continental Concern Score. Hooded Oriole is not on the 2016 State of North America's Birds' Watch List. In some areas, especially where ornamental palms have increased, Hooded Orioles are expanding and moving farther north. But in the lower Rio Grande Valley in Texas, populations are declining. The main threat to populations in the lower Rio Grande Valley is cowbird nest parasitism. Brown-headed and Bronzed Cowbirds parasitize Hooded Orioles by laying their eggs in an oriole’s nest. The new parents unwittingly care for cowbird young and Hooded Oriole young rarely survive. Back to top

Backyard Tips

Try attracting Hooded Orioles to your yard with oranges, sugar water, or jelly. Slice oranges in half and secure them to a post or other platform. Or hang up an extra hummingbird feeder with slightly larger holes to allow these larger birds to access the sugar water. Use the same proportions you would for hummingbirds: one part table sugar dissolved in four parts water. Be sure to dispose of any fruit that becomes moldy because some molds create toxins that are harmful to birds.
