UPDATE, June 14: In the video player above you can watch the first video to show the recently born Mexican gray wolf pups at the El Paso Zoo.

ORIGINAL REPORT, June 10: EL PASO, Texas -- The El Paso Zoo's Mexican gray wolf pack has now grown larger.

Zoo officials on Thursday announced the recent births of a half-dozen new gray wolf pups, four males and two females, in what they called an "exciting milestone... (in) the repopulation of this endangered species.”

"The (newborn) pups are healthy and are venturing out of their den for the first time. In addition, the pups join their three older brothers," the zoo said in a statement.

The parents of the pups came by way of a transfer from the Phoenix Zoo when the El Paso Zoo added its Chihuahuan Desert exhibit.

"(It) allowed us to get in the new mom and dad wolves and subsequently have these pups," zoo officials said in the birth announcement. "This is an exciting day for the zoo and the wolf population."
