ID Help, please! Black-headed, Rose-breasted, or Hybrid?

[Peter Knoot]

This good-looking bird showed up in our back yard in Northern California a few days ago. At first, my wife thought the bird was an injured female Black-headed Grosbeak because she spotted pinkish patches on the base of the wings and on its breast. Upon closer examination, it is not injured but is showing the onset of pink coloration of a juvenile male Rose-breasted Grosbeak (which is not common on our Left Coast). The beak is not totally pink nor distinctly bicolor. Could this be a hybrid male?

Looks like an adult non-breeding male Rose-Breasted Grosbeak to me.

[Axel Hildebrandt]

My best guess is juvenile male Rose-breasted Grosbeak.

Ditto on the Juvenile Male RB Grosbeak

Beware of berry stains...
