Oriole Facts and Figures
Female orioles build hanging, teardrop-shaped nests high up in trees such as cottonwoods, maples and elms. Their woven nests consist of milkweed down, dog hair, weed fibers, wool and many other fibrous materials. You can encourage nesting orioles to visit your yard by hanging a Best Nest Builder™ ball as a source of nesting material and by providing appropriate food choices throughout the summer.
Orioles incubate 4–5 eggs over 11–14 days. They have only one brood each year and the nestlings fledge 11–14 days after hatching.
Male orioles do not achieve their brilliant adult plumage until the fall of their second year. Until that point they’ll resemble a female oriole with drabber pale orange colors, often with slight shading around the head.
Midwestern Oriole Species
Here in Minnesota, Baltimore Orioles are common. However, the Midwest also hosts oriole species such as Bullock’s and Orchard Orioles.
