During the early weeks of May, Mexican wolf pups made their way from their home in New York to a wild den in Arizona. The practice, known as cross-fostering, takes a pup, bred in captivity, and places it with a foster mom in the wild. Den locations are found based on the information obtained from the radio collars the adult wolves are wearing.

Experts with our partner, Mexican Wolf Species Survival Program, assess the number of pups that can safely be incorporated into the litter. It is important not to overtax the female wolf. 

The Mexican wolf was eradicated from the wild in both the US and Mexico. A captive breeding program, initiated from only 7 unrelated wolves, saved the Mexican wolf from extinction. The US Fish and Wildlife Service began releasing Mexican wolves from captivity into the wild in Arizona and New Mexico in 1998. Limited genetic diversity remains a threat to the wild population of Mexican wolves.

The direct flight, in the comfort of the cabin in Ken’s Cessna Citation, ensured the wolf pup arrived in Arizona quickly and with as little stress as possible, including getting fed during a short fuel stop in Missouri. 

After arrival in Arizona, the pup was placed in a wild den with its new pack. Its presence will increase the genetic diversity of the Mexican wolf population in Arizona. Cross-fostering pups into wild dens allows for these animals to be raised in the wild by experienced wolves. This wolf pup joins an established wolf pair along with new pups and will bolster the Mexican wolf population in the region.

We’re grateful for the generosity of volunteer pilot Ken Adelman. These flights require more flexibility around timing and expectations than most LightHawk flights due to unpredictable whelping dates of both wolves in captivity and those in the wild where the pups will be placed.
