How does this even happen?

The rare Canadian Winter Caneffoffnow builds its nests from snow, high in the treetops of the Rocky Mountains. This elusive bird has never been captured on film, despite hanging around for way too long each spring. Look out for these nests when enjoying a walk through the 5 feet of highly compacted snow, just don't stand directly under them.

I don't mind winter but seriously, enough is enough!
