very cool. the wolves have a building? I was under the impression that their holding was outdoors(covered roof, but open). maybe things have changed by usfws and ssp standards.
I think the wolves (both Gray and Red) have covered outside holding, but I think with the completion of WOLF in 2006 they added indoor housing. An article about the new Mexican Wolves says "While the wolves will spend much of their time outside, they have quieter, concrete digs built underneath the spectator’s room. There, they have a bedroom with heat, air conditioning and bowls that automatically fill with water."
