Oak Titmouse
A couple of close encounters of the Oak Titmouse kind occurred recently; today on a hike along Rattlesnake Canyon when I came upon a pair of parents feeding youngsters hidden inside the cavity of a trunk. The first encounter was in the Figueroa Campground, where I was able to record the bird with what seems to be three call variations.

Possibly (this is a guess), the bird wanted to communicate alarm about my presence, but could not do so vocally with food in its beak. Needless to say, I left immediately after taking the photos.)
