Orchard Oriole
Orchard Oriole
Icterus spurius
At a Glance
Most common in the Midwest and South is this small oriole. It favors open areas with scattered groves of trees, so human activities may have helped it in some areas, opening up the eastern woodlands and planting groves of trees on the prairies. Orchard Orioles often gather in flocks during migration. The black-throated young male, sitting alone in a treetop and singing his jumbled song, is often confusing to beginning birders.

Behavior
Eggs
4-5, sometimes 3-7. Pale bluish white, blotched with brown, gray, purple. Incubation is probably mostly or entirely by the female, about 12-15 days; reportedly, the male may feed the female during incubation.
Young
Both parents feed the nestlings. Young leave the nest about 11-14 days after hatching, may remain with one or both parents for several weeks. 1 brood per year.
Feeding Behavior
Forages mostly by searching for insects among the foliage of trees and bushes. Regularly visits flowers, probing in the blossoms with its bill. In winter in the tropics, often forages in flocks.
Diet
Mostly insects, some berries and nectar. Diet in summer is mostly insects, especially caterpillars, beetles, and grasshoppers, plus many others, also spiders. Eats some berries, perhaps more in fall and winter. Often feeds on nectar, and may eat parts of flowers.
Nesting
Male sings in spring to attract a mate. Often not strongly territorial; in some cases, more than one pair may nest in the same tree. Also sometimes nests in the same tree with Eastern Kingbirds. Nest site is in tree (usually deciduous) or tall shrub, rarely in tall dense marsh growth. Often 10-20' above ground, can be much lower or higher (3-70' up); typically placed in fork of horizontal branch, sometimes in clump of Spanish moss or other site. Nest (built by female, possibly with help from male) is a hanging pouch or basket, not as deep as some oriole nests, woven of grass and plant fibers, lined with fine grass and plant down.
Climate Vulnerability
Conservation Status
In recent decades, has decreased in many parts of range but has increased in some regions, such as northern Great Plains.
