I have mentioned "my" Mockingbird here before. He used to land on my hand and eat live mealworms from my open palm.
I have also complained about his lack of success in finding a mate. He sang continuously - including all night long, until he finally attracted a little grey feathered cutie.
Today, he has been having a fit - really aggressive with other birds on the feeders (ten feet from his nest). He has been chasing the cat next door. He attacked the squirrels when they came to feed today. And when the little boy up the hill walked by, the Mockingbird popped him in the back of the head twice. As usual, he didn't pay much attention to me when I was out and let me take his picture as usual from about six feet away.
