Orioles are similar to the hummingbird in that they require just a bit of individual care and they are migratory, traveling in the spring and early summer. Orioles prefer their own special nectar, which requires a distinctive kind of feeder in order to accommodate their feeding habits. In addition to nectar, they will eat damaging caterpillars and insects from your trees. Having an Oriole feeder will guarantee that these amusing and vocal orangey yellow and black songsters flock to your backyard.
