Decorah, Decorah North
Baltimore Orioles glean for food in the foliage of trees, shrubs, and bushes. They eat nectar, a wide variety of invertebrates, and fresh fruit. During the summer, their diet includes beetles, crickets, grasshoppers, moths, spiders, snails, caterpillars, webworms, gallworms, raspberries, mulberries, blackberries, and cherries. Although Baltimore Orioles don’t have to cope with ice and snow, they add more fruit and nectar to their diets in the spring and fall to help fuel breeding and migration. They will come to feeders for pieces of fruit, jelly, or sugar water.
Female Baltimore Orioles weave their remarkable hanging nests from grass, strips of grapevine bark, wool, hair, and artificial fibers like twine and fishing line. They nest near N2B and the Decorah North nest, and we’ve seen them stealing nest materials from Decorah North. Their nests are usually 3 to 4 inches deep, with a small opening on top and a bulging bottom chamber for eggs. Baltimore Orioles lay three to seven bluish-white to pale gray oval eggs with brown and black markings concentrated at larger end. They produce one brood per year, although they may reclutch after nest loss. The female incubates eggs for 11-14 days and both males and females feed young, who stay in the nest for 11-14 days before fledging. To learn more, visit Cornell’s website.
