A big deal for me, anyway. That little gent with the red bib and the big bill is a Rose-breasted Grosbeak. Hit the link and check out his range map. How'd you wind up in California, dude?
This is actually a wide-ranging [or wide-roving] species, and sightings here in California are "regular but rare," according to the Interwebs. I took these snaps near Big Bear Lake, CA in early August.
"How you doin'?" Couple of nuthatches to the right of the feeder, and down in the lower right-hand corner, a female Black-headed Grosbeak. I think. Click for [a bit] bigger.
