I have a window feeder on two different windows about 5 or 6 feet apart. Constant activity and constant fighting between the birds -- most often one bird doesn't like another one sitting at either feeder. Sometimes there's an air fight between three or four or five hummers.

They are always females.I can't remember if this has always been so at our feeders, but a neighbor down the street tells me that she has only males at her feeders. Do other people find that they have only one sex or another?
