I had seen them before and I know that they roam the skies of this neighborhood to hunt. However, at the time of this photo it was not my intention to capture it in image. So it's time to thank that concatenation of fortuitous events (luck) that allowed me to do it.
What you see In the photo it is a kestrel. A little falcon, a bird of prey that his preferred hunting system is to stalk from an innkeeper. Likes to stand on a high branch, pole or anything where he can have a panoramic view of his surroundings, watching for any small animal that runs nearby; or a little bird that flies nearby. With an agile and fast flight, it also usually stops in the air while observing the place. Some people here have them as pets or trained.
I am pleased to share this image with you that I personally loved especially because of its unexpectedness.
