Coopers Hawk. They, along with Sharp-shinned hawks, are primarily bird hunters.Yes, it was beautiful flying around and landing several times on the run and adjacent shed.
I knew it couldn't get at the chooks, so I just enjoyed the show.
If you take the time and make the effort to build proper coops and pens, then like Aart you can enjoy watching the wild animals we share this world with without constantly worrying about your birds, or killing off creatures that are only trying to live in this world.
