Biologists found that the bison are not purebred; their ancestry includes genes from the cattle. They also found that they have a smaller size, different length of legs, jaw length overbite, low fertility, and behavioral problems (such as punctuated walking in tight circles).
Probably due to founder effect--inbreeding.
The scientific study determined that a herd of between 150 and 200 would be good for the bison, and less ecologically damaging for the island. Beginning in 2009, the herd was given animal birth control to maintain the population at around 150 animals.
Animal birth control? What the fuck.

It's absurd.
