The Baltimore Oriole (Icterus galbula) entry from All About Birds says (in part):
The rich, whistling song of the Baltimore Oriole, echoing from treetops near homes and parks, is a sweet herald of spring in eastern North America. Look way up to find these singers: the male’s brilliant orange plumage blazes from high branches like a torch. Nearby, you might spot the female weaving her remarkable hanging nest from slender fibers. Fond of fruit and nectar as well as insects, Baltimore Orioles are easily lured to backyard feeders.
…Baltimore Orioles are more often heard than seen as they feed high in trees, searching leaves and small branches for insects, flowers, and fruit. You may also spot them lower down, plucking fruit from vines and bushes or sipping from hummingbird feeders. Watch for the male’s slow, fluttering flights between tree tops and listen for their characteristic wink or chatter calls. Look for Baltimore Orioles high in leafy deciduous trees, but not in deep forests: they’re found in open woodland, forest edge, orchards, and stands of trees along rivers, in parks, and in backyards.
Baltimore Orioles seek out ripe fruit. Cut oranges in half and hang them from trees to invite orioles into your yard. Special oriole feeders filled with sugar water supplement the flower nectar that Baltimore Orioles gather. You can even put out small amounts of jelly to attract these nectar-eaters (just don’t put out so much that it risks soiling their feathers). Planting bright fruits and nectar-bearing flowers, such as raspberries, crab apples, and trumpet vines, can attract Baltimore Orioles year after year.
