ID confirmation of a couple Carrizo Plains Rodents

I was out at the Carrizo Plain last week and did quite well, despite being limited to the paved road at the southern end, due to extremely wet and muddy conditions. I spent about 3 1/2 hours there, hiking and cruising, and conservatively saw 60+ rodents. There were at least 7 species, however I was only able to photograph 2.

I’m pretty sure these are San Joaquin Pocket Mice, Perognathus inornatus.

I think this is Peromyscus maniculatus.

I also saw the 3 K-rats, Southern Grasshopper Mouse, and a California Pocket Mouse.

Thanks,

Curtis Hart

Yep, both IDs seem correct to me.

The ID’s look good. What three K-rats did you see? Or were they three of the same? The Carizzo is a spectacular place for sure.

  Dipodomys heermanni
  Dipodomys ingens
  Dipodomys nitratoides
  
  I didn’t get the greatest looks at the smaller ones, but I did see all three, sometimes at once. Of the 60+ rodents that night, I’d say 40 or more were K-rats.

  BTW your unknown snake is a Gopher Snake, Pituophis catenifer.
