(KUSA/CNN) – It's a bison baby boom in Colorado. The herd at Genesee Park, outside of Denver, has possibly hit a record size.
Caretakers say it's all thanks to a young bull who was recently introduced to the herd.
The mothers keep the calves in the more forested areas during the day, but the come out for water in the evening. It's good time for visitors to try to catch a glimpse of the young calves.
