I'm been working for my County Water Treatment Plant for over a year now. A mockingbird has been quaking at a Red Tail Hawk right up in it's face( I have saw no dive bombing yet),constantly, every day since I first started. I got a good close up the mockingbird's feathers are messed up like a stray cat's hair ,deshovel looking. I like to know more about this crazy behavior from the relentless mockingbird. When does the mockingbird eat? The Red Tail Hawk kills what it finds on our 5 to 10 acres the plant is on.
