There are oak woodlands nearby, the Bushtits' favored habitat.

Bushtit (Psaltriparus minimus) Is a tiny songbird in the Long-tailed Tits (Aegithalidae) family. It is one of the smallest passerines in North America, at 11 cm (4.3 in) in length. It is gray-brown overall, with a large head, a short neck, a long tail, and a short stubby bill. Bushtits are sexually dimorphic. The male has dark brown to black eyes and the adult female yellow eyes. Coastal forms have a brown "cap" while those in the interior have a brown "mask." There are several subspecies.
It forages actively in trees and shrubs. Diet is mostly insects. Feeds on a wide variety of tiny insects, especially leafhoppers, treehoppers, aphids, scale insects, caterpillars, and beetles; also wasps, ants, and many others, including eggs and pupae of many insects. Also eats some spiders, berries, and sometimes seeds.
Per INat @/billhubick : "Listen for any simple, endlessly repeated song at this time of year. The note is variable but the pattern is distinctive. They are also especially fond of live oaks. In fact, if you haven't already heard it, you'll be delighted to hear their nickname of "spirt of the live oak".
