Learned something new today.  Immature Rose-breasted Grosbeaks are nearly 
identical to Mature Female Black-headed Grosbeaks.  Peterson's was 
incomplete on this and my own bias at having seen so many Black-headed 
females in Colorado led me to making a rookie mistake.  Checked Sibley's and it 
confirms what others have been pointing out to me.  

Rookie mistake and I appologize to everyone for posting incorrect information.  

I have issued a retraction in ebird and will delete this bird from CACHE.

My only consolation is that it was my first ever Immature Rose-breasted 
Grosbeak male.

Good Birding,
