"Bison calves have been born in Alberta's Banff National Park for the first time in 140 years, Parks Canada officials said on Tuesday, marking a milestone in attempts to reintroduce a wild herd to the area.

Conservation officers said three calves had been born since Saturday in the remote Panther Valley on the eastern slopes of the Rocky Mountains and that seven more were expected, the first such births in almost a century and a half in the area now making up the park.

Western Alberta is dealing with unseasonably cold spring weather, but Bill Hunt, resource conservation manager for Banff National Park, said the calves were well-equipped to deal with harsh conditions."
