Our crabapple trees are in full bloom. Yesterday 2 male and 1 female Baltimore Orioles were drinking nectar from their blossoms. We watched through the window with our binoculars, then I went out to take photos. We never tire of these beautiful birds.
If you want to attract orioles, plant crabapples. They also sometimes come to orange halves or oriole feeders filled with sugar water, just like hummingbirds. When orioles beging nesting they usually just eat protein in the form of insects and caterpillars, and may leave the nectar and oranges. So don't be surprised if they stop coming to your oriole feeder. They also feed protein to their babies.
