This hummingbird feeder looked good, seemed to be built well, had an ant moat and a wonderful mounting loop. After two weeks in service it was crawling with bees. They drained it dry. Upon inspection it was obvious that the joint on the top and bottom halves of the feeding station portion of the feeder had not been glued or sealed properly. The bees were drinking the nectar from that leaking joint. I'll try re-gluing the joint. Very disappointing.
