Peter's Feeders has been making quality feeders since 1982 & they are still the best! Our OR-1 Oriole Feeder was one of the first feeders we designed 30 years ago & it works so well it is still the design we use today! Orioles find the deep, vibrant orange of the base & top of our oriole feeder irresistible. The color draws them in naturally as ripe, juicy fruits do in the wild. We use the same proven clear, up-swept feeding tube design as our HB-1 Hummingbird Feeder which allows easy access for the much larger orioles & still allows you to watch them drinking. One of the best perks of this feeder is that it not only attracts orioles but Indigo Buntings, Purple Finches, American Goldfinches, & of course hummingbirds all enjoy drinking from the OR-1, too! The larger birds mentioned don't feed while hovering so we designed the feeder to have a generous pair of non metallic perches, but even hummers will land for a break while feeding. Here's what some of our customers have said about Peter's Feeders OR-1 Oriole Feeder & we have these letters on file: We would like to purchase 1 or 2 more because the orioles seem to prefer this type of feeder. We absolutely love your feeders. We have tried in the past to get orioles & thanks to your feeders we are successful. We also have many other varieties of birds we've never had before. The birds absolutely love this feeder & out of my 17 hanging throughout the yard, this is by far their favorite. We designed the OR-1 to be easy to fill & it holds 8 oz of nectar (sugar water). Peter's Feeders are handmade in Wisconsin from impact resistant plastics, the feeders come with instructions for making your own nectar & are very easy to use. Expect a variety of visitors to your Oriole Feeder!
