This Northern mockingbird is always somewhere around the garden in neighbors' trees, singing its full repertoire of at least 15 songs of other birds that frequent the area.
So far I haven't seen it act particularly territorial toward other birds.
If you look carefully, you'll see the mockingbird's silhouette on the branch of another tree.
It is almost in the center of the photo, on the topmost thicker branch .
The bird is facing left.
And there he is again.
