A young Cooper's Hawk is perched and hunting in the Backyard and has the Blue Jays seriously upset and alarming and then the squirrels join in with their alarm calls and it goes on for over 30 minutes. You can also hear Catbird's and a Cardinal sounding the alarm. Cooper's Hawks are the real Backyard predators of songbirds, especially Doves and it is rare that they expose themselves like this, maybe because this one is not fully mature. See a Cooper's take out a Dove at:    • Cooper's Hawk Kills

They accelerate rapidly and can strike from shortrange unlike the larger Red Shouldered or Red Tailed Hawks it is interesting to note that the Blue Jays are not messing with this Hawk and attacking it like they do the bigger hawks. I'm not sure why but it may be because they know this Hawk has no sense of humor!
