First posted by Sarus at - shaggygod.proboards.com/ Does the jaguar limit the presence of the Andean bear in the Amazon rainforest? It was previously noted that the Andean bear seemed to avoid the jaguar, since its altitudinal ranges in Peru and Bolivia did not overlap on the slope of a single mountain (Peyton 1999). However, in this study it was determined that in the same areas where the Andean bear was recorded in the PNYC-RCY and the RCA, a high activity of the jaguar, presenting a greater relative abundance than the bear. Moreover in the PNYC, in a tree of Ormosia sp. (Fabaceae) were found marks left by an Andean bear and a big cat, the later very likely a jaguar. This suggests that the presence of the jaguar would not influence the displacement of the Andean bear to and in the BTA, at least in the directly evaluated areas.

So, according to recent evidence, the Andean bear has little or no fear of the jaguar.

www.arkive.org/spectacled-bear/tremarctos-ornatus/ The spectacled bear is generally solitary, although it has occasionally been seen feeding in small groups. Mating may occur at various times of year, and the female usually gives birth to 1 to 3 cubs between December and February, after a gestation period of 5.5 to 8.5 months. The cubs may stay with the female for up to a year. Predators of spectacled bear cubs include pumas (Puma concolor), jaguars (Panthera onca), and adult male bears (6) (9) (10). The spectacled bear may live for up to 39 years in captivity.

www.animalspot.net/spectacled-bear.html Predators The only known predators of the spectacled bear cubs include pumas (Puma concolor), jaguars (Panthera onca), and other adult male bears. *Note: Jaguars, pumas, and Andean bears all dwell within the Andean Mountains. There is no evidence of predation on adult bears by either of the big cats.

While the boar Andean bear can be from about 50 to 100 pounds heavier than a jaguar, the she-bear is pretty much at weight parity with America's biggest of the cats. The giant anteater normally weighs less than 100 pounds; much smaller than a jaguar. Jaguars prey upon giant anteaters; however only from behind or from ambush. A bear is a much tougher opponent than an anteater.

Ranji says: The true Panthera cats are known to be fundamentally more aggressive than Cougars in general, as an example, the only Jaguar known to be in the CONUS, 'El Jefe' is also on record as a bear-killer. Wrong. Jaguars do not hunt bears. Cougars do not hunt bears.

Ranji says - Seems as if the Cougar is a particularly bloody-minded individual, and hell-bent on bear-killing, then its - game on! Stupid thing to say. Cougars lose their hard-earned kills to wolves, black bears, and grizzlies every day. I am seriously getting tired of your spam.

I have found no confirmed accounts of a cougar, a jaguar, or a leopard ever killing a mature bear of any species. Ranji, you are not signed up. You do not wish to be part of the team?

... shaggygod.proboards.com/ There are additional relating points to communicate. IIRC, on a South American nature reserve, one female spectacled bear was found dead. A cougar was suspected in her death. In another event, as explained from a foreign documentary on spectacled bears (either in Portuguese or Spanish) the larger male spectacled bear was filmed displacing the smaller cougar from its kill. Keep in mind, although the spectacled bear's diet is largely plant based; animal matter is also a part of their diet. In some areas, some spectacled bears become conflict animals as they will prey on farmer livestock including cows.

shaggygod.proboards.com/ Bear Rehab & Release "Bear release is the ultimate aim of the rescue program of our conservation project. Rescued bears need rehabilitation to learn what to eat in the wild before they can be liberated, also to grow big enough to avoid attacks by puma". "The Andean bear rehabilitation process takes anywhere from 6 to 18 months, depending on the age and size of the rescued cub. Bears must be large enough to not be attacked by puma or other predators before they can be released".

Predators of Andean Bears... Zero natural predators for adult Andean bears. Jaguars ( should there be any in the bear's domain ) and pumas will prey upon juvenile bears. All juvenile animals have predators. I believe that adult Andean bears walk without fear of large cats. Their only fear is of man.

correct me if I am wrong but it seems the jaguar treats the spectacled bear as a prey in areas where they overlap. While I generally support bear over pantherine at parity, the spectacled bear which is a member of the short faced bear family does not have grappling techniques as good as a cat (according to a source on Carnivora). What do you guys think?

What do you guys think? No evidence has been found of jaguars hunting and killing an adult Andean bear. In fact, the bear shows no signs of fear of big cats ( puma and jaguar ). Also, as the Andean bear is a tree-climber, he has very likely developed better grappling ability than his giant ancestors had - but I have no study-material to prove this.

Do jaguars prey on andean bears?

I would not refer to the Andean bear as an apex predator. He consumes very little meat; mostly vegetarian. But, he is a bear and only cubs need fear cougars and jaguars.

This is about the only (possible) interaction I have found between the two: "The most secretive bear we have had at Chaparri who would often not be seen for days at a time. She arrived in 2001 from a circus that arrived in the village of Chongoyape and was believed to have originated from the Chachapoyas region. She escaped undetected from the enclosure during the wet season of 2006 when the vegetation is very dense and she was being seen only occasionally and was found dead outside the enclosure - the exact cause of death is not known but she appears to have been killed by a Puma." www.chaparri.org/en/andean-bear-rescue-centre.phpcarnivora.net/showthread.php?tid=6794Credited to Taipan.
