This bird had me going. For awhile I thought it might be a California Towhee which would have been pretty unusual as their range is not this far North. I was even considering requesting help on the internet. Then, while paging through my field guide, I came across a picture of a female Brown-headed Cowbird. It looked similar, so I did a web search and am now very certain that this is a female Brown-headed Cowbird. Nothing exotic (I was getting a little excited that I may have had a significant sighting), but I learned something new and that is one of the things that I like about this hobby.
