Biologists captured every one they could find in Texas and Louisiana and bred them carefully, so that the pups were as much like the original red wolf was possible. In 1987, eight red wolves were released in North Carolina s Alligator River National Wildlife Refuge. There they produced a number of litters. When the wolves were set free, they wore collars with radio tracking devices in them, so any that stray onto private lands can be found and retrieved. Breeding pairs have also been released onto four islands off the southeastern coast of the United States.
Some scientists think that the red wolf is really a hybrid, a mixture of wolf and coyote.
But there are no coyotes or gray wolves living in nature near the reds, so any interbreeding has stopped. Wolves main diet is deer, caribou, bison, moose, and elk. Wolves can go at a steady trot for eight hours. Pups are always born in the spring. There are 4-6 wolves born in a litter.
