Nira, the orioles like oranges, grape jelly, and later in the season they feast on bugs! Like flying nasty bugs... mosquitoes anyone? The nectar in the feeders is a simple mixture of 2/3 cu sugar to 1 quart of sterile water. There are nectar feeders, which is what the orioles are sitting on, and the one has the additional cup to hold a half an orange. They prefer the fresh fruit but I also saw one of the ladies on the nectar section last evening. Good luck!!!!!!!!!!!1
