How is that this owl is living in the snow? The owl has adopted to its environment. Nature found a way to make it work. We tend to find ways to go against nature. Let's get back to being one with nature.
I've seen small birds drive away an owl before, and I think that's what is happening here between a songbird & a Barn Owl. It's astonishing to witness the bravery of small creatures protecting their young and/or their territory.
