Not if you have a lot of birds in your area.
I wrote a long post or two about my local cooper's hawk that showed up after the local redtailed hawks were displaced by new construction. Nothing tells you you're 50 years old and twenty feet up a tree quite like having a larger female perch next to your head and look you square in the face.
From your picture I'd say she is staking the area out for birds coming to feed on those dried what'sits that's hanging from that bush she's perched in.
A friend of mine who tracks told me how to not blame the cat for small bird mortalities and that is if you find a LOT of feathers are lying around it was more than likely a bird of prey as cats aren't thorough in plucking birds. So if you find patchs of feathers that include even the downy ones it's probably the cooper's hawk.
