Thanks Bob, nice to know who gave em the name.
I haven't seen Abert's squirrels in the Eastern part of the Gilia. We were right at the Arizona State line near Luna, NM. I think they are thicker the closer one gets to Arizona. One hunter shot one with a black belly. He said it was only the second one he has ever seen that color and he has hunted that area for decades.
I grew up hunting fox squirrels in East Texas, Abert's squirrel was a new experience for me.
