Jaguar Predation
|
From the Study by Maria Renata Pereira Leite: RELATIONS BETWEEN THE JAGUAR, PUMA AND LOCAL RESIDENTS IN THREE CONSERVATION UNITS OF THE ATLANTIC FOREST OF PARANÁ STATE, BRAZIL.
https://acervodigital.ufpr.br/bitstream/...sAllowed=y City: CURITIBA YEAR: 2000 4.6 Cases of predation on domestic animals. 47 records were made of alleged cases of attacks on domestic animals attributed to jaguars and pumas. In 18 of the records, the attack of jaguars and pumas on domestic animals was confirmed involving the loss of 59 animals, one buffalo of two years (predated by jaguar) (Figure 22), 2 adult bovines (one predated by jaguar and the other predated by puma), 8 calves (jaguar and puma), 28 sheeps (jaguar and puma), 1 pig, 18 goatlings and one chicken (puma). In all of these cases the attacks sites were close (= or < 500 m) to the forest edge. In all proven cases ideal conditions of animal management were not observed, mainly in terms of containment, since in all cases the animals had free access to forest areas. Figure 22.

Lisa Antell: " World Photography Day 2020
Posting one of my favorite photos ever, and probably the photo that made something “click” inside of me. I am very much an amateur photographer but my interest was sparked dramatically after seeing this gorgeous jaguar, Juru, in the Pantanal in Sept 2018 while traveling with Panthera. Juru was full of youthful, exuberant jaguar energy and confidence, and he charmed me completely! "

"The information obtained shows what wild animals are his favorites. “We have detected two capybaras, three donkeys, a white-lipped peccary (Tayassu pecari), a baby tapir (Tapirus terrestris spegazzinii) and a wild cow, although his favorite prey are anteaters: he has already hunted five,” says Cerón. Dr. Quiroga shared an interesting piece of information in this regard: “In a publication three years ago, we reflected on the difference in anteater numbers, which are much higher in the Argentinean Chaco than in Paraguay and Bolivia. At that time, we explained this was due to the lack of jaguars in the region, which is its main predator. Knowing this information now corroborates the data.”

Just as I thought, jaguars are predating on wild horses in los Llanos according to photographer Ernesto Badog who spent a lot of time in the Aurora Reserve in the Colombian Llanos tracking jaguars and studying the fauna of the area:
 *This image is copyright of its original author "Wild horses have been grazing on here (Aurora Reserve) for years, it's incredible to see them running through the savanna during sunsets. Wild horses too make part of the jaguar diet!" Through my talk with Jorge Barragán, the owner of the hato, his claims that he hadn't witness predation were most likely refering to the domestic horses used to gather the cattle which are kept indoors and protected. It's important to highly that these reserves in los Llanos boast from hundreds to up to thousands of wild horses depending on their size. A study I read on the ecology of wild horses in hato El Frío, Venezuela, spoke about the pack of observed predation on horses by big cats due to the absence of said cats on the hato. I'm now interested to know of the people at Panthera who are doing plenty of work tracking these jaguars have more information about the predator-prey relationship between jaguars and wild horses, this is fascinating. @epaiva @peter and everyone else might find this information interesting as well!

@epaiva thanks a lot for that information, it's fascinating to see this dynamic of jaguars hunting equids, especially because equids were thought to be part of the diet of jaguars during the Pleistocene in both North and South America before they went extinct 8,000 years ago. I read on a book about Llanos history that on the Venezuelan side alone there was an estimated 300,000 horses roaming free, my guess is that I'd you add Colombia the population was probably at around half a million a few centuries ago. This huge concentration of large ungulates skin to what is seen in Africa could very well explain why the historic sizes for Llanos jaguars were so big, and why I don't think that the claim of the male shot in Cojedes who allegedly weighed 180 kg is necessarily unfounded. If some jaguars managed to actively hunt 300+ kg horses on a regular basis, then of course they'd grow enormous.
Base on the books and studies I have read on Llanos wild horses, they seem to have developed a ton of anti-depredatory measures to fend off cougar and jaguar attacks, including living in very large herds to more easily spot danger, and avoid congregating near the gallery forests (especially at night) where the jaguars recide. I'll go into more detail about it once I have more time, but this dynamic is fascinating as I said. Lions in Africa aren't the only big cats bringing down equids.

Feral hoggs from Venezuelan Llanos, they have huge fangs a lot like the ones of Wild boars. A person that witnessed the battle of a big Jaguar with a Feral Hogg pictured its huge fangs said that the Jaguar did not make a frontal attack it attacked the Feral Hogg until it was tired and killed it with a powerful bite

@epaiva do you know by any chance anything regarding the population of wild horses in the Venezuelan side of the Llanos? Are they are plenty as they were before? In Colombia there are areas where they are still protected, these are the areas where I'm the most curious to see that rates of predation by jaguars. This is the only documentary that I know of which features wild horses in the Colombian Llanos (min 22:56)
As for feral hog, here is a clip of Totin female from Aurora chasing some hogs into the forest, you can see how big those hogs are compared to her: The Llanos is full of large prey for them. |
