I am late getting my hummingbird feeder ready this year and because of that, I have not seen one hummingbird rushing by. Usually they are knocking each other off the feeder and last year there was one who would go sit in the tree nearby and wait for his chance to have the feeder all to himself. That was unusual as they generally are very aggressive toward each other. I hope word gets out that I now have the feeder full with the red, sweet stuff so my little friends will visit. I love them.
