Eric Zetterholm is an amateur photographer, but you'd never know it by this photo. It's a male Northern Harrier.
They have an owl-like face that allows them to hear mice and voles in the meadows below them. These slim hawks holds their wings in a V shape in air. Their call is a high-pitched "kek, kek."
