unk bird again

Can anyone identify this bird? It and another one were foraging on one of our trees in the shade garden. It had a rufous cap, a buff belly, and a greyish brown back. It didn’t have any speckles or barring that I could see. Its legs and bill were black. I tried looking in a bird book but couldn’t find anything that matched it.

*It’s a little smaller than a sparrow, with a longer beak; it wasn’t very timid or nervous while it browsed. It struck me as being round and fat with a relatively large head compared to its body as opposed to being lanky. Its cap wasn’t bright red but was a reddish brown compared to the rest of it.

**I think it’s a bushtit, Psaltriparus minimus
