Black-headed or rose-breasted grosbeak Boulder

[wwi...@gmail.com]

This morning I saw what looked like a non-breeding female black-headed or rose-breasted grosbeak in our yard. Yellow under-wings, some streaking along sides but not on center of breast. Bill rather pale and not clearly bi-colored. Any help with more definitive ID would be much appreciated.
