I will be taking a US road trip in late May 2015 to photograph various mammals and would appreciate any help that you can provide regarding a few species, some of which are fairly easy to see, but not always as easy to photograph.
I already have sites for several of the mammals that I would like to shoot, but do not have reliable, or hopefully easy, destinations for American Beaver, American Marten, Ringtail, North American Porcupine, Kit Fox and Swift Fox.
Long-tailed Weasel would also be great, although I know that one is much less likely.
The trip will start in LA, but I do not intend to travel as far north as Martinez for the Golden Beaver, and I will also visit Arizona, partly for Black-footed Ferret, New Mexico, hopefully for Swift Fox, and finally Colorado.
I have read most of the recent trip reports regarding these areas, but any updated information or more or less guaranteed sites for these six animals would be greatly appreciated.
Thanks for any help in advance.
