[EBB Sightings] Family day at Sunol: Bushtits and What?

Friends!
I was at Sunol-Ohlone Regional Wilderness today (Wed., August 13, 2008) and 
strolled along the creek from the Family Camps west of the Old Green Barn 
down to the cor-ten bridge that spans Alameda Creek east of the Classroom 
building. I saw a motley crew of bushtits, a few adults and at least a 
half-dozen juveniles, with downy feathers still at the base of their legs, 
and only the central tail feathers grown out.
There were a pair of adult Steller's Jays and five birds with them which I 
took to be juveniles of jays, but they were not blue at all- they had brown 
"shawls" (scapulars), and were otherwise mostly gray. And they had large 
bills and the beginnings of crests.
Too large to be Oak Titmice with crests, the bills were black or blackish 
and kind of large for the heads that bore them. They were interested in 
acorns, bits and pieces of acorn shell, and they had that hop that reminds 
me of a sack race or three-legged race at a picnic.
Google only presents images of very blue juvenile Steller's Jays, with a lot 
of black in the head and crest, which the birds I saw lacked.
The two adult jays seemed to be associated with this mob, but what were 
they?

Any help would be appreciated. Sorry, no photos. I am barely out of the 20th 
century and don't have that digital stuff (yet).

Best of birds to you!
