Bought two of these after seeing orioles at our humming bird feeders. The bottoms of each are made in two parts that screw together. The problem is that both of them slowly leak out through this joint and will become empty overnite. They are worthless!Opus 449-2 Oriole Feeder

We tried another brand of oriole feeder two summers ago and had to get rid of it because of the problem it created with the local bees: some crawled into the feeding holes and drowned, others created a swarm around the feeder, and the rest decided they owned the patio and chased us indoors. The spring-loaded bee guards on this model keep the bees at bay--in fact, they don't even try to get into it--and the orioles have had absolutely no trouble pushing past the guards to get their drink. I did notice a slow-drip leak after a few days, but fixedd that easily by making sure that the two parts of the orange (bottom) portion of the feeder are screwed together completely. Other reviewers have written that they'd prefer a glass upper canister instead of plastic, but be careful what you wish for. One heavy-footed oriole landed so hard on this feeder that she knocked it off its mounting hook; the feeder fell 6 feet and landed on the concrete patio without breaking. All things considered, I'm delighted with this design and plan to buy a spare before someone changes it.

I purchased one of these a year ago, when I noticed the Scott's Orioles trying to eat out of our hummingbird feeders. They were unsuccessful, as their beaks were too large. I found one of the Opus feeders online, and when it was installed in our yard, we had an Oriole invasion; both Scott's and Hooded Orioles congregated around it. One smart family even built a nest about 10' away from the feeder! It's easy to clean and fill, easy to assemble, and the birds love it. The only thing that might improve this feeder is if the reservoir was glass instead of plastic, but we're very happy with it.

I bought this feeder from Target after seeing an oriole near our regular bird feeder last spring. It shipped quickly and was easy to set up once I bought some oriole food mix. I hung it as suggested in a southwest corner but never saw an oriole come near it! I gave it a few weeks but no luck so I moved it under a tree. Maybe I put it out too late in the season and missed the migrating males this year so I'll give it another try next year. I still have it up since it looks nice but it didn't seem to attract any orioles this year. I'd give it 2 stars but I'll give it through the summer and put it up early next spring and see if anything changes.

Update:The Orioles will NOT feed from this feeder. I have lots of Orioles,the other feeders ran out for two days and they left because they would not eat from this feeder. I filled the ones back up that look like big oranges and they are feeding again. I believe they will not eat from this one because it does not have feeding station pegs for them to stand on while feeding and the others do. P.S. Humming birds will eat from the same orange shaped feeders with the Oriole necter food,in case you do not want to put both out or do not have room for both kinds of feeders.
