SCIENTIFIC NAME
Icterus galbula
DESCRIPTION
Smaller than a robin, the male oriole displays a brilliant orange breast, shoulder patch and rump contrasted with a black head, back, wings and tail. The female resembles the male, but is paler in colour, displaying a dull orange breast with a dark brown olive colour on its head and back. The male has a beautiful flute-like song, which he performs throughout the summer. The female’s song, in comparison, is shorter and simpler. While songs vary slightly from one bird to the next, they always have the recognizable “hew-li” sound.
RANGE
Baltimore orioles return from their wintering grounds in Mexico or the southern coast of the United States to their Canadian breeding grounds in spring. Their breeding range expands from Nova Scotia west to a small area in British Columbia.
HABITAT
They have a preference for deciduous trees and open areas and have adapted well to parks and suburban regions.
DIET
While caterpillars form a large part of their diet, orioles also eat spiders, grasshoppers, crickets, beetles, butterflies, moths and fruit.
BEHAVIOUR
undefinedPRIMARY ECOSYSTEM ROLES
Because Baltimore orioles feed on caterpillars, they play an important role in protecting forests from pests such as tent caterpillars, fall webworms, gypsy moth larvae, tussock caterpillars and spiny elm caterpillars.

The Delightful Baltimore Oriole
By Terri-Lee Reid
A favourite among bird watchers, the Baltimore oriole is a pleasure to spot in one’s backyard.
To attract this beautiful bird to your yard, refrain from using pesticides, as this can kill off or contaminate the oriole’s main food source. If you have the space, grow one of their favourite trees for nesting or grow shrubs and other native plants to create additional habitat for insects. You can also grow fruit-bearing plants such as Rubus spp. (raspberries) and Prunus spp. (cherries) as another food source. To supplement, you can place orange sections and bananas on feeders. If Baltimore orioles are near, they will bring their young with them once the young are ready to leave the nest.
Perhaps this will be the summer that a Baltimore oriole visits your backyard.
