By "bulldog bear" as stated they are referring to the short broad skull of Arctodus. Some, in the biology community refer to the bears of the genus Ursus as "dog-skulled bears" and all others as "cat-skulled bears". The skull of Arctodus does indeed resemble a tiger skull. The nick-name bulldog bear is misleading as a grizzly is physically more like a bulldog than Arctodus. The giant has long slender legs and straight pointing feet. Ursus arctos has a broad build with slightly bowed legs and feet inturned like those of a bulldog ( designed for grappling ).

Quote from book ( above post ) - The short faced bear was a predator of all other bears and every other living creature. It stole the kills of dire wolves and saber tooth tigers. I disagree a great many people on this. It has been made clear that despite his long-legged build, Arctodus simus was not an active predator. He also lacked the grappling ability of the bears of the genus Ursus. I believe that this giant was a scavenger and did indeed drive other predators from their kills. But I believe that it was the big cats more than this giant bear that plagued the grizzly.

Well its not like the short faced bear was not a predator, he just did not predate much. We agree that he was mostly a Kleptoparasite thats for sure.

I'm sure he would make an occasional kill, on easy to catch prey. In fact, I have no doubts that when man met giant bear, he met his worst nightmare. Talk about your easy prey!

This is probably what would have occurred back in prehistoric times. Nice visual picture King Kodiak.

Exactly. A bear of this size have a good chance of displacing 2 big cats from a carcass.

The name isn't romantic at all; Kleptoparasite. But this is what bears do. The giant short-faced bears and probably Agriotherium made a living at displacing other predators from their kills. Any other predator! This was their livelihood. They might have munched on vegetation occasionally, but their lives depended on finding and taking a carcass. Most paleontologists agree to this. The modern grizzly, more than any other living bear, is a kleptoparasite. But other bears do this too. If there were leopard seals in the extreme north arctic, a polar bear would not hesitate to displace the seal from a carcass ( would probably eat both ).

Kleptoparasites are more like usurpers rather than scavengers correct me if I am wrong. Leopard seals will not be able to escape from a polar bear on land especially if there is no breathing hole nearby not to mention the seals of the antartic are not conditioned to flee as they would rather fight as they are use to being safe on land.

The Grizzly is my favorite thief and my favorite parasite... and my favorite mugger.

Notice the word “habitually”. That is why even though tigers can sometimes steal kills from Dholes or leopards, its not very habitual. Thats why i dont think tigers are oficially classified as Kleptoparasites.

Thats why i dont think tigers are oficially classified as Kleptoparasites. I don't believe that anyone ever has. The cat fan-boys enjoy their idea that being a full-time predator makes their cat superior to a bear. My point of view: it is the bear that displaces the cat from his kill. Edit and add: I have yet to see a cat displace a bear from a carcass.

There is a reason most times they dont defend.

Brown bears, black bears, lappet faced vultures, blue jays, ravens, etc fall into that category.

Brown bears, black bears, lappet faced vultures, blue jays, ravens, etc fall into that category. Hmmm..? Debatable. We must separate the term scavenger from the term kleptoparasite. Sure, the bigger birds will chase away the smaller birds from a carcass. But, does this move them into the category of kleptoparasite? In some locations of Africa, lions feed more on hyena kills than from their own hunting. This might place this particular group of lions into this category. Wolves will chase off a cougar or a wolverine from a carcass. But I can't see this placing them under the title of kleptoparasite. I tend to think that kleptoparasite is referring to a carnivorous animal which is a scavenger who routinely displaces predators and other scavengers from a carcass as his ( or her ) normal survival strategy. Wolves are hunters who will occasionally displace another animal from a carcass. This might be said about any and all predators and scavengers. Bears, nearly every species, is a scavenger and a kleptoparasite. A bear will follow the trail of an active predator, knowing that in the end there is a chance of a feast.

Well, some animals like the lappet faced vulture and white headed vulture make good predators are well as kleptoparasites because their beaks enable them to reach into fresh hide (which is especially so with the former) and they make a living of robbing eagles smaller than themselves.

I wish I could meet russian biologists to get their thoughts of what happens between a a dominant male adult tiger and a dominant male adult brown bear. I would also ask them if tigers ever took kills fro m large adult brown bears. Im sure it don;t happen very often but you never know.

Go over the “tiger vs grizzly thread”.
