Bushtit Eating Blackberry

I was watching a flock of bushtits move through the landscape. They fluttered and tumbled into a thicket of blackberries that were growing up through a cottonwood tree. As I peered through the foliage, I found some of them eating the blackberries. I captured one plucking off one drupelet at a time. I love its stance of one leg down grasping a tree limb and one nearly straight up holding onto the berry. I imagine the thorns of a blackberry are potentially harmful to birds. They have easily torn open my skin on more than one occasion when I was picking the berries. This one is playing it smart and showing off its acrobatic skills by finding a safe place to perch away from the thorns.
