Any knowledgable birders out there? I've dabbled at birding for decades but have only recently gotten serious about it.

I have a question to which I can't find the answer by searching. I've read many presentations and references about mockingbirds but none mention whether mockingbirds ever gather in a flock and fly around. Do they ever engage in flocking behavior?

My guess is no, but today I observed a flock of about a dozen birds that flew quite close to me several times and they looked like mockingbirds. Obviously, I could be mistaken. Haha.
