I haven't seen that one yet, but I'm on my third Oriole feeder...two of them with that type of "bee guard". The first one, I didn't use the bee guards, and the birds loved it for two years. ..until the bees discovered it. I drowned about 200 bees before the fledglings left and I could remove it. That was with those guards in place. The new one this year, the birds don't like. The holes are too small, so they take one pass at it and go to the hummer feeder. I noticed today that the little yellow ball was stuck open on one port, and had to shake it a bit to get it to close. The first one I got was one of those pretty mason jars with the metal base. The birds loved that one, but the first season they had destroyed the soft port covers. By the end of the second season the ports were bare metal.
