The Orchard Oriole swaps the typical flame-orange of other orioles for a deep, burnished russet. Hopping among riverine shrubs or scattered trees, male Orchard Orioles sing a whistled, chattering song to attract yellow-green females. The smallest of North America’s orioles, it gleans insects from foliage and builds hanging, pouchlike nests during its brief breeding season, and then heads back to Central America for the rest of the year. Orchard Orioles also feed on fruit and nectar in orchards, gardens, and elsewhere.
On their favorite habitats—along river edges, for example—Orchard Orioles nest in groups, often with multiple nests in a single tree. On less suitable habitats, however, they tend to be solitary. Orchard Orioles migrate north late in the spring and head southward early, with some returning to their wintering grounds as early as mid-July. Because of the short breeding season, researchers have trouble distinguishing between breeding orioles and migrating ones in any given location. The Orchard Oriole eats nectar and pollen from flowers, especially during the winter. It is a pollinator for some tropical plant species: as it feeds, its head gets dusted with pollen, which then gets transferred from flower to flower. Sometimes, though, the oriole pierces the flower’s base to suck out the nectar—getting the reward without rendering a service to the plant.
