Near the start of the East Glacier Trail, a flurry of activity caught my eye. Creeping closer, I saw two male juncos in major conflict. Usually, male birds settle territorial border battles by visual displays and songs. But that wasn’t enough for these guys, who were going at it hammer and tongs. Fluttering up and down, chest to chest, pecking each other and buffeting with wings, until finally one rode the other down to the ground and held it there, whacking it for almost a minute (that’s a long time, if you are the whack-ee). Then they separated.
