Eight Oriole Species Brighten Summer Backyards Across the U.S.

I could be forgiven, being a lifelong Baltimorian and a serious baseball fan, for having a special affection for orioles, but I am not alone. For many bird watchers, the return of orioles in the spring is a special moment.

It is not just that orioles are beautiful, the males a palette of rich oranges, yellows, and blacks, or that their song, familiar and resonant, rings across the landscape. It is that no matter where you live in North America, you have a chance of seeing one. Including a few orioles that are confined to the southern border of the United States, eight species regularly occur in North America. Many bird watchers forget that orioles are members of the blackbird family, along with grackles, cowbirds, and meadowlarks. Unlike their cousins, however, orioles are usually found singly or in pairs rather than in flocks. Small groups of orioles may be seen in the fall, but they are exceptions rather than the rule.

Baltimore oriole

In much of the East, from southern Canada to the northern edge of the Gulf States, when bird watchers think oriole, they are talking about Baltimore orioles (birds, not ballplayers). The Baltimore oriole, formerly considered the same species as the Bullock's oriole of the West under the name northern oriole, is a bird of open woods and parklands. Its fondness for areas with scattered tall trees means that it frequently is a backyard nester, to the delight of the homeowner. The long, hanging nests, which may take as long as two weeks to weave, are large enough to be fairly easily found, although they are usually high in trees and at the ends of limbs.

Baltimore orioles eat mostly insects but will take fruits and will also feed on sugar water at nectar feeders. Many backyard bird watchers put out orange, melon, or apple slices or purple grapes for their orioles.

Baltimore oriole populations are considered stable, but many older bird watchers have commented on how much scarcer the birds are now than they were 25 years ago. Some researchers think the populations may be declining because of the loss of large insects.

Bullock's oriole

The western counterpart is the Bullock's oriole, found from southern Canada to the Mexican border. The Bullock's also favors open woodlands, although it is most often found in cottonwoods rather than in the Baltimore oriole's favored elms. Particularly a bird of stream sides and parks, it is found fairly frequently nesting in yards with scattered trees. It is as fond of fruit and sugar water as the Baltimore oriole and will readily come to feeding stations that supply them.

Orchard oriole

Although the orchard oriole's range overlaps that of the Baltimore oriole, the orchard oriole is considered a bird of the Midwest and Southeast. It breeds in open areas with deciduous trees and sometimes in yards. In general, the orchard oriole uses areas that have shorter trees than Baltimore orioles prefer and can sometimes be found in shrubby areas with half-grown saplings. Orchard orioles regularly feed on nectar and may use hummingbird feeders. The orchard oriole population may be declining slightly in some areas, but in the past century it has expanded its range north almost to the Canadian border, perhaps as a result of the clearing of native forests. The nest is like the Baltimore oriole's, but it is not as deep. Oddly, orchard orioles can often be found nesting in trees with eastern kingbirds, although the kingbirds will not tolerate a Baltimore oriole nest close to their own.

Hooded oriole

In many ways, the western counterpart of the orchard oriole is the hooded oriole. The males of the two are distinctive, but even experts have trouble telling the females apart. Hooded orioles are largely confined to lower elevations in the arid Southwest, favoring yards, parks, and streamsides. Hooded orioles are particularly attracted to palm trees and are one of the most frequent oriole visitors to nectar feeders. They have expanded their range slightly in recent decades, although the range may have declined in Texas because of cowbird parasitism of nests.

Scott's oriole

Another Southwestern oriole is the Scott's oriole. It favors dry habitat in foothills and valleys, particularly in areas with yucca, in which it likes to nest. Like the other orioles, it is an insect eater, but it will come to nectar and occasionally to fruit. The Scott's oriole has spread slowly northward in the past few decades.

Spot-breasted oriole

The spot-breasted oriole is a species introduced from the tropics that has become established in parts of southeastern Florida, where it takes advantage of the many tall, exotic trees. It eats many flowers and fruits and will take nectar. The population seems stable.

Altamira and Audubon's orioles

In extreme South Texas, along the lower Rio Grande River, are two other orioles that are part, barely, of the North American avifauna. Altamira and Audubon's orioles are birds of tropical forests and thickets. They are widespread and fairly common in Mexico. Both take fruit as well as insects and will come to feeders.

For those with orioles in their yards, summer is a slightly better time, a little richer experience. Oriole parents are persistent tenders of their young and defenders of the nest, providing plenty of opportunity to study or just to watch. Those who do not have orioles yet and who have at least a few tall trees can try to attract them with fruit slices—oranges and grapes—and a nectar feeder. Many oriole fans put out nectar in cups, which are easier for the orioles to get to than the nectar in hummingbird feeders. Success is not guaranteed, but if it works, adding orioles to your yard is something you will never regret.

  • I have the same situation. The feeder is attached to the middle of a large picture window that goes ceiling to floor w/ no ledge or sill for animals to climb or balance. Yet every morning all the sunflower seeds have been cracked open and hulls left. Any ideas what it is?

  • I have a bird feeder that sticks to my window and I've been hearing noises against the window at night right now its going on. But whatever it is it is aware of me. And when I get to window it leaves.I can't imagine a squirrel or mouse or possom being able to get at it. ...So as I was reading this article im to assume no bird eats at night. Or no birds will eat at night. Why is that? Then im also thinking of a sinereo that could a lost confused bird eat at night. This eating thing is watching meI turn out the light go there noise dissappears..Thank you.

  • I never knew feeding birds could be so confusing. I love watching the birds in my backyard even though I don't get a very big variety.
