If this were anywhere near April 1, I would assume it was a hoax. As it is, this report from Sporting Classics Daily borders Cryptozoology. It purports to be a note on a scientific report, on a new species of “ground” squirrel, from Borneo, the “ground” in quotes, because though to all appearances it appears to be a rather typical, tassel- eared, old world tree squirrel. It also looks like our own local Abert and Kaibab populations, but for the bushiest tail I have ever seen on any squirrel, tree or ground… (here is a similar one):
The sources, at Smithsonian and Science, seem legitimate. But it gets truly weird: according to local legend, it kills (small) DEER. And eats their internal organs. It is being studied with camera traps, which have given us a lot of intriguing and sometimes confusing data.
Read it, and let me know if you find anything further?
