It sounds to me like the mockingbirds are possibly protecting a nearby nest they fear will be targeted.
nope the cat has been here 6 years and up til a couple weeks ago we have always multiple species of birds frequenting the yard.
They get a break for a few more weeks to get through this breeding season but if it keeps up its off to the local Airsoft store
