A Bird In The Window

I'm casually sat here, reading over notes on social policy..lone parents..child mortality, and i'm disturbed by the shadow of a bird heading straight for me. The window breaks it's flight, and it falls to the roof of our porch. I clamber up on the desk, to peer down at the little bird, hanging upside down, watching it's feathery chest rise and fall. His wings are open full spread, still upside down, and after 3 minutes, i'm beginning to wonder if he's about to die.. My father (the resident Ornithologist) informs me it's a Nut-Hatch, and the poor little bird is in a state of shock. Apparently, this type of species often engage themselves in peculiar positions if they feel they are under attack. Maybe this is why he is still hanging upside down, head facing the ground. He's lost a few feathers, but after 10 minutes, he brushes himself off, and continues his journey.
