I have a huge pine tree (easily 30’ tall or more) in my yard that a gang of mockingbirds moved into a couple of years ago. They show the local squirrels no mercy at all.
Their morning songs are really something to hear. Vast repertoire.
I once worked for a Baltimore hospital, famous for having Al Capone as patent.
Ole Al loved a room by the hospital’s huge crabapple tree.
When I worked there the mockingbirds loved that tree as much as Al Capone.
First thing they all learned, from baby up…Imitating an AMBULANCE!
Its funny to watch mockingbirds dive-bomb cats. :)
