CHICAGO (AP) - Four pups of a critically endangered species of wolf have been born at Lincoln Park Zoo in Chicago.
The zoo says in a news release that the two male and two female red wolf pups were born April 13 - the first new litter of red wolf pups at the zoo in nearly a decade.
Curator Dan Boehm says the arrival of the pups comes at a time when scientists estimate there are fewer than 30 red wolves left in their native habitat of North Carolina.
The wolves - named for their red-tinged fur -have over the years been driven to the brink of extinction by hunting. The zoo is taking part with other zoos in a Red Wolf Species Survival plan to increase the red wolf population.
