Does anyone have any links or sites that would show me pictures of craws and their seasonal color change in different regions in the US? What Im really interested is the pictures, Im having trouble locating sites that has them.  Thank You.

I have seen this before, but I still can't figure out the key.

I have tried several but have not found a good one yet.

If you highlight everything following the blue "KEY", you can see some text that explains it, and that wasn't visible to me to start with.

thanks, been trying to figure that out for a while.

click on; state to open up species, use nav bar to view various photos, click on the photo to enlarge.

Hundreds of color photo's available on this site.
