Zion Rodents – ID required

Here are a final set of photos from Jean-Michel Bompar of 4 rodents caught near the southern entrance of Zion national park.

Animal 1 below had a HB length of 95mm and the tail was the same length.

Animal 2, 2 pictures below, had a HB length of 95mm and a tail (with a tuft of hair at the tip) of 81mm

Animal 3 below had an HB of 98mm and a tail of 80mm

Animal 4 below had an HB of 90mm and a tail (with a tuft of hair at the end) of 92mm

Again would anyone like to give an opinion as to what species these are?

thanks

Jon
