The Baltimore Oriole – (Icterus Galbula)

How The Baltimore Oriole Got Its Name

It received its name from the resemblance of the male’s colors to those on the coat-of-arms of Lord Baltimore.

Baltimore Oriole - (Icterus galbula) is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of Lord Baltimore. Find plenty of Baltimore Orioles on the UWGB campus walking trailing every summer.

Female: The adult female is yellow-brown on the upper parts with darker wings, and dull orange-yellow on the breast and belly.

Juvenile Orioles: look similar to the female, with males taking until the fall of their second year to reach adult plumage.

You Normally Hear Them Before You See Them

What A Baltimore Oriole Eats

1.) Baltimore Orioles forage in trees and shrubs: They seem to prefer only ripe, dark-colored fruit. Orioles seek out the darkest mulberries, the reddest cherries, and the deepest-purple grapes, and will ignore green grapes and yellow cherries even if they are ripe. Baltimore Orioles sometimes use their bills in an unusual way, called “gaping”: they stab the closed bill into soft fruits, then open their mouths to cut a juicy swath from which they drink with their tongues.

2.) They mainly eat insects: making short flights to catch insects in the sky.

Favorite Prey:

Their favorite prey is the tent caterpillar moth, which they typically eat in their larval stage. If you have ever had the pleasure seeing them eat tent caterpillars, it is comical. They beat the larvae against a tree branch removing the skin and hair of the caterpillars. I feel no remorse for giggling at the behavior. Tent caterpillars are nasty!

How You Can Attract Them To Your Yard

1.) Sugar Nectar Feeder: If you do not have an oriole feeder they have often been seen sipping at hummingbird feeders. (Sugar Water Recipe)

2.) Halved Orange: They will absolutely stop at your feeders to enjoy. (Birds that Eat Oranges)

3.) Grape Jelly: Provide shallow dishes with store-bought dark colored grape jelly. During spring and fall, the sugary jelly is readily converted into fat, which supplies energy for migration.


The Baltimore Orioles nest is built by the female. It is a tightly woven pouch located on the end of a branch


The female lays three to seven eggs. The eggs are pale gray or white with a slight blue tint. The incubation period is 12 to 14 days.

Feeding Young

Both parents find food for about 14 days for their young.  They feed the young by regurgitating what they have consumed.
