Good fences make good neighbors (?)

This photo, taken by Warner Glenn in 1996, is believed to be the first of a live jaguar in the United States.

On the CNN homepage today:

Jaguars, an endangered species, have a breeding population in northern Mexico. Scientists believe there are no more than 120 left in the wild there. It's believed that since 1910, the cats are only visitors north of the border. They have been virtually unstudied here until recently but any possible return of breeding jaguars to the United States could be stopped by the new border fence. Last month the Department of Homeland Security waived 30 environmental laws to finish 470 miles of the fence by the end of the year.
