I love them they are so beautiful!! We had to take ours down we used to have a bazillion of them come to feed and one year the bigger one came and chased all the others away he came everyday and i loved it but he started getting more aggressive every year till he started attacking us when we were outside he would dive bomb us flying right past our faces. he would zoom up in the air in a U shape and them try to attack us. so we took the feeder down
