Demarcated Landscapes has this post concerning the death of an Arizona jaguar that was recently collared in an effort to track its movement.
This is a particularly saddening loss – there have been only 4 jaguars known to have visited north of the border in recent years. Macho B was the most frequently seen, visiting annually since at least 1996 and he was the only jaguar known to visit this year. One of the 4 was killed in Mexico. With the border wall advancing, the sunset on jaguar inhabitation of America becomes more and more evident.
