Feisty Chickadee: During nesting season one male attacks his reflection. He’s an angry bird!

We are so lucky to have so many wild birds on the homestead and the chickadees are some of our favourites. They are so friendly and follow us around as we are working but during nesting season, one of the little males gets super feisty. We have window clings but it doesn’t matter, he just keeps attacking his own reflection, thinking it’s a rival male.
