They are excellent parents to their little offspring and one is always on guard.
Cleverly, they built their nest in the prickly bougainvillea; its large thorns providing protection from inquisitive cats and me!
Every time I go out there they fly to a nearby tree and chirp at me most vociferously. Here one perches in the grape vine to get a better look at me.
They fly to other trees as I pass by, continuing to scold and making sure to see me on my way.
How dare I trespass on their territory!
