We think there is a peregrine hunting over our house and local park. It is more than likely as we have our (famous) peregrines on the Newton Building and another breeding pair on the Gedling Church spire. Evidence for this?
Being me, I grabbed the camera, a pair of gloves and headed out to photograph it. The wound under it's wing was extensive and torn; you can see the the stain on the wing from it's bleeding. Whatever hit it was strong and with ripping gear attached. As a sparrowhawk is generally equal to a magpie in size and unlikely to have the strength for this size of bird we dismissed it as an unlikely suspect. A peregrine however, is just the right size, speed and agility to aim for a prize of this size.
We have since scanned the sky but have not seen the culprit since. I am afraid the magpie went to join the wildlife cemetery at the bottom of the garden. But not before I took a range of photos. They have the most beautiful plumage and delicate lines. The iridescence of the purple and blue is stunning.
