GardenAccentHeaven’s selection of Oriole bird feeders will help to attract orioles, and solve some issues that you will encounter with feeding orioles.  . We recommend that you clean and refill your oriole feeders twice weekly, so that the nectar does not start to ferment.  Also, if feeding jelly, keep an eye on it and clean and refill the jelly jar whenever needed  If  you hang your oriole feeders in the shade the jelly and nectar in the oriole feeder  will last a little longer than if left  in direct sunlight.
