All the following rodents were trapped in desert scrub near Rodeo just over the Arizona border.
The first two mice were found in the same trap!
The smaller grey individual had a body length of approximately 5.5cm and a tail of similar length.
It’s mate (below) had a body length of 8cm and a tail 7cm long. More photos of both are available.
The final unidentified mouse (below) had a body length of 9cm and a tail of 8cm.
Just for interest sake I was pretty successful trapping in the desert. Mammals I did manage to identify included Merriam’s Kangaroo Rat, Chihuahuan Pocket Mouse, Tawny-bellied Cotton Rat and several handsome Western White-throated Woodrats
The latter were happy to take the bait but didn’t appreciate the free accommodation.
Thanks again for any help.
