Baltimore Orioles bird feeders.
 

Anyone having luck attracting Baltimore Orioles to your yard?

We used to feed tons of birds at our prior home in Missouri. The only reliable way I ever found to attract Orioles was by offering oranges and grape jelly. An orange sliced in half will catch their attention, and bring them to your yard. Placing a container of grape jelly near the orange is the payoff for them. Once the Orioles get accustomed to you providing them with jelly, you can do away with the oranges. Orioles absolutely love grape jelly, and they are voracious eaters. We would have to refill the jelly cups daily for them. We even had one that would come sit on a rail outside my wife's office window and squawk at her if the cups were empty!
