Twin bison were born at the Salato Wildlife Education Center in Frankfort on Friday morning.
"The first one was born about the time everyone was arriving to work this morning," said Salato Manager Laurie Davison. "The second was born around 10:30 a.m., right in front of several hundred visitors."
"Everyone was able to watch the calf drop," Davison said. "After an hour, it was able to stand for the first time and it began to nurse. There was quite a crowd watching, and cameras going off everywhere."
Each calf weighs 40 to 50 pounds, and stands 2½ feet tall at the shoulder. Calves retain a reddish color for the first months of their lives.
The two newborns join six adult bison at the Salato Center.
Visitors wishing to see the calves may visit the center between 10 a.m. and 5 p.m. Eastern time Saturday, May 23. The Center is closed on Sundays and for the Memorial Day holiday on Monday.
The center is on U.S. 60 in Frankfort, 1.5 miles west of U.S. 127.
