I have had a female spotted towhee at my feeders for several weeks. Yesterday a male showed up for the first time. My resident wasn't happy. She chased him all over the side yard and the field next to the house every time he came near a feeder. She seemed to get used to him later in the day and allowed him to eat, as long as he didn't get too near to her. She has not been at all aggressive against birds of other species at the feeders--wonder if the male committed some towhee faux pax.
