The Santa Ritas jaguar, the only known one in the U.S., has been sighted recently by USFWS scientists. (For more pictures and information, click on the image.)

The jaguar’s roar is tremendous, but more commonly it sounds like this (if it sounds at all). Just so you know, when you’re hiking out there.

The jag, a male, is as yet unnamed. Voting for a name is open until October 20 at the Center for Biological Diversity.

The Weekly Green has written in ‘Nils’, as a more manageable form of the Navajo word for ‘Wind’ or ‘Air’, Nilch’i.
