Frosty
One of my favorite things about sub-zero mornings is seeing Otto's frosted eyebrows. Moisture from his breath condenses on his brows and freezes. It had started to melt away by the time I took this photo, but you can still see some droplets frozen above his eyes. Sometimes I feel bad for the birds sitting out in the cold all night. But Otto's many layers of feathers are so good at insulating that not enough heat can escape to melt the frozen droplets. Great Horned Owls really are built to live all seasons in the Northwoods!
