2nd bird definitely male Bushtit - it has a dark eye.
1st bird has a pale eye, so could be either female Bushtit or Wrentit. If it was together with the 2nd bird, then female Bushtit.
They're also semi-separated by habitat - Wrentit tends to be in lower, drier chaparral (dense low stuff mostly less than a metre tall), Bushtit in moister, taller shrub & tree habitat. Does that help here? Also Bushtit often in flocks, Wrentit solitary or in pairs (family groups just after fledging only).
