This Oriole bird feeder is perfectly made to feed orioles. The feeder itself is orange, and orioles are naturally attracted to the color orange. So, with this feeder, you will have them in your yard in no time. As long as you feed them what they love, nectar and oranges, this feeder has been specially made to accommodate them. It has four feeding ports and four jelly trays on the cover; it holds 12 oz. of nectar, a half-orange, and jelly. It also has an ant moat and bee guards built in, with a brass hanging rod and is made of high-quality material, so it will last me for a very long time. I was so excited to see the orioles stopping by and grabbing a bite every time I tried to take a picture. They flew away. What a great addition to my backyard.
