I learned something today that I evidently missed a couple years ago. What we have been calling the Western Scrub Jay is no more! What was called Western Scrub Jay species has been split in two. We now have the California Scrub Jay, the one that we see here year round, and Woodhouse's Scrub Jay. I got this nice shot of the California Scrub Jay in Delta Ponds.

Here is some good information on the name changes from Feedwatch.org - http://feederwatch.org/blog/farewell-western-scrub-jay/ The article is entitled, "Goodbye Western Scrub Jay"
