injured kestrel

on this mighty windy morning, i heard, and then saw, an AMERICAN KESTREL fighting the wind to land on the spire of a Victorian building in Wicker Park. I was looking into the sun, so it wasn't a great view, but this bird seemed to have in its beak a bunch of nesting materials, or perhaps stringy entrails. Its tailfeathers seemed to be flopping wrongly, almost as if they were about to be torn loose from its body. i wondered if it had just experienced some trauma as it struggled for purchase on the rounded brass spire. Once it gained footing, it lifted its wings again and was borne off on a gust of wind. i couldn't follow its trajectory over the building, and lost sight of it behind a chimney.
