Re: Rose-breasted or Black-headed Grosbeak
Streaks in the middle of the breast look thin to me. They are usually
thick mid-breast on Rose-breast. The more pigment in the ground color, the
stronger the streaking on Black-headed. Rose-breasted females and young
are not normally this buffy on the underparts.
Here is a fledgling Rose-breast and female from last week near Pescadero...
And here is a female Rose-breast from my yard in Pacifica this Spring...

During the Fremont Birding Circle Facebook group monthly walk at California Nursery Historic Park in Niles. Fremont this (7/11/2015) morning, we encountered a juvenile grosbeak that I suspect it might be a Rose-breasted Grosbeak. The bird has a speckled white throat, streaked breast and heavily streaked flank. However, the beak color is dark gray instead of typical pale pinkish. Here is a shot by Chinling Tien posted on the FBC site:--
