ID for some mammals from California/Arizona – part 2

Here is part 2 of my unidentified mammals.

1. Yosemite, Tamarack Flat Campground. Deer mouse?

2. Kangaroo rat from Mojave National Preserve (near Mid Hills Campground). Desert kangaroo rat?

3. A gopher from the Black-footed ferrets near Seligman. Botta’s pocket gopher (photo taken with my mobile phone, since I forgot to take my cameras…)?

4. A rat from Madera Canyon. I saw several of these at the feeders of Santa Rita Lodge. Some kind of woodrat?

5. Another rat from Madera Canyon (maybe the same species as the previous one?). These were seen near the Proctor Road Parking Area.

6. Kangaroo rat from Borrego Palm Canyon Campground in Anza Borrego. Dulzura is the one seen there, so I guess the photo shows this species?

7. Another one from the same location.

8. A kangaroo rat from Joshua Tree, near Hidden Valley Campground. Desert?

And to end some kangaroo rats from Carrizo Plain. I mainly drove the road to Selby Campground, and saw quite some k-rats. I found these difficult to ID however… I didn’t see any foxes or antelope squirrels in Carrizo.

9. Giant kangaroo rat?

12. The last one, could this be a San Joaquin kangaroo rat?

Thanks a lot for any help!

    Hi Simon, 4 & 5 are Yellow-nosed Cotton Rats, when I have some time I will look at the other pictures though that won’t be for a few days and I expect others will be able to help before that.

      Thanks Jon! I had noted them as that species first (because of the yellow :-)), but when looking in my field guide I thought they didn’t look like it at all… Thanks a lot!

    #1 is Deer Mouse; #2 is Merriam’s (Desert would have white tail tip); #3 got to be Botta’s since it’s the only one there; #6 is likely Dulzura (note longer, more pointed ears than in Merriam’s); #7 can be either of the two, but probably Merriam’s; #8 is possibly Agile (similar to Dulzura but slightly darker; both occur in JT); 9-11 sure look like Giant; #12 is a baby Giant (San Joaquin would have smaller ears and less black tail tip).

      Thanks for these too, I messed up the k-rats, I will have to go back one day to really get into their identification… Happy with the Giants, I saw about 15 of them on the road to Selby campground. Good to see there were some babies around too! I probably saw San Joaquins too, but have no pictures of them.
