The nasty weather early this week brought as many as 20 juncos to our deck feeders. They picked at thistle seed and sunflower parts in the snow. Maybe juncos are aggressive because they don’t like to share. Maybe hormones are beginning to run spring high. In any case, threats and combat were common. Get too close and the birds would face-off, chests out, posture rigid, bills pointed high. This would last a second or two before one of them attacked. There was jumping and lunging with talons extended for battle. The fights were brief, the winner claiming the right to feed undisturbed for another few seconds
