Mexican Jaguar Census Shows Big Cats Increasing In Number, Conservation Efforts Are Paying Off

Jaguars. AKA Panthera Onca, are the largest big cats in the Americas. They were once common from the southern United States deep into South America. Although they remain common in some areas their population is under threat in others. The successful results of a recent Mexican jaguar census shows conservation efforts are working. It also may accelerate efforts to reintroduce the cats to the United States. Jaguars were extirpated from the United States. A few are crossing the Mexican border and may recolonize Arizona.

Jaguars are among the many spotted cats in the nearly 40 member cat family. . They resemble leopards, but are not too closely related.

One difference in appearance is that jaguars have spots within spots

According to Britannica:

“Jaguars are also larger and more heavily built than leopards. The male jaguar, which is generally larger than the female, attains a length of 1.7–2.7 metres (5.6–9 feet), including the 0.6–0.9-metre (2–3-foot) tail, with a shoulder height of 0.7–0.8 metre (2.3–2.6 feet); it weighs from 100 to 160 kg (220 to 350 pounds). South American jaguars are larger than those of Central America. The jaguar is grouped along with lions and tigers with the big, or roaring, cats and is the only such cat in the Western Hemisphere. Its sound repertoire includes snarls, growls, and deep hoarse grunts.”

Meanwhile, a handful of male jaguars cross into Arizona. There are no females reported so the population is not established. Conservationists are seeking to start a breeding population. Females must be present to bring cubs into the region. A formal reintroduction effort is being urged.
