Polar bear meets Grizzly

[Deleted]

Yes she did. This was the first article on news about grizzlies invading polar bear territory.

Wow ok. That was some ferocious mother to charge 4 male polar bears. I would love to see the account.

In Pleistocene Europe, we now know that there was the occasional breeding of grizzly ( Steppe bear ) and cave bear. There were therefore very rare cave grizzlies roaming the land.

Another account:

By chance, I was able to watch another video meeting on Planet Green's Expedition Alaska Episode 2 (2008) of a grizzly bear - polar bear encounter. This meeting is a different video footage from the earlier Discovery Channel film. The location in and around the Prudhoe Bay area is the same as the earlier DC documentary, however, the dynamics and end result a little different. In this case, local native hunters having completed their whale hunt (by law, they are allowed to hunt whale) left behind discarded whale meat which attracted about 40 polar bears which is amazing in of itself because of the solitary lifestyle of the polar bear. During the night a barren ground grizzly bear emerges to join and eat the left over whale meat remains. As seen in the DC documentary, the presence of the grizzly bear caused about one-third of the polar bears to exit but there were a majority two-thirds who remained (they were the larger older males). The whole Planet Green Expedition Alaska Episode 2 grizzly bear/polar bear encounter film was short in duration not even thirty seconds: GRUMBLE, GRUMBLE . The grizzly bear & polar bears ate side by side. Because the sea ice had not formed, the left over whale meat help to feed the polar bears and bridge the gap of time until the sea freezes over allowing the polar bears to move away from land and hunt seal on the frozen ice. In any event, pretty cool footage!

Oh man that is some rare pictures there. It has to be the only pics of a polar and a brown bear together in an enclousure.

Here is the full story:



Even from a distance, the size of these two once furry little cubs is impressive.

Ahpun is clearly the largest tho' Oreo (wearing the wet look) seems to be the more aggressive of the two.



Looks pretty impressive upclose, huh?



Every time Ahpun looked like he was going to get in the water, Oreo rushed over to discourage him.



It's interesting that I titled this "Ahpun Thinks" in my mind as I snapped the button cos about five minutes later I heard a regular visitor telling someone else that while Oreo was clearly boss at this point, Ahpun was more of a thinker and problem solver. Found that interesting. Here he'd just stuck his head in the water for a quick dunk and seemed to be waiting to evaluate Oreo's reaction.



Since he couldn't get into the water, Ahpun figured he'd pretend to be a bridge, I guess.



Oreo makes a splash



Oreo was in the water almost all the time I was there, giving me a look at the back of the bear-do here, I guess.



Next shot, he was so close to the glass and the window divider that all that's really clear is that there is a bear in there somewhere.



I'd seen the bearcam many times but had always thought the bears' enclosure was larger, tho' it wasn't. Here they're seen from the viewing platform to what would be sorta back and right side on the bearcam.



Oreo had an eye on the trout the zoo had just stocked their beary-pool with.



That's one wet bear!!!

Here is the full story. Anyway both bears are females wonder why they put 'he'. Oreo is now with a male brown bear called Jake and another female name izzy:

There is a petition which claims the zoo is negligent but the zoo denies it. Ahpun now lives alone:

Grizzly-Polar bear hybrids have been documented to rarely occur in the wild, as well as in captivity. It is only since 2006 that these have been confirmed to have been naturally occurring in the wild. Polar bears and Grizzly bears fill different ecological niches, so even when the two live in the same areas, they avoid each other for the most part. Polar bears tend to breed on the ice, while grizzly bears tend to breed on land. It is unclear how the two come to naturally hybridize. It is suggested that climate change may be the cause of naturally occurring hybridizations. The reduced number of ice flows may drive polar bears in toward the land during mating season, increasing the likelihood that they will come in contact with a grizzly.





These two species of bears are able to interbreed because they evolved from a common ancestor relatively recently (compared to the evolutionary timeline) - only about 150,000 years ago. This means that the bears share high genetic similarities. It is also suggested that polar bears may have evolved from brown bears when a population migrated north towards the ice.


The Pizzly bear, or Grolar bear share characteristics of both the polar bear and the grizzly bear. The body size of the hybrid is smaller than the polar bear, but larger than a grizzly. As well, the face of a pizzly bear is not as wide as a grizzly bears, but not as narrow and long as a polar bears. The animal does has a similar neck length to a polar bear, and has small shoulder humps like a grizzly would have. The fur of the pizzly bear appears to be patches. The dark patches are made of up hollow orange-brown fur, while the white patches are hollow clear fur.




The behaviour of pizzly bears seems to be more similar to that of polar bears than of grizzlies. These behaviors include stomping toys (as a polar bear would do to break ice), hurling toys side to side (as a polar bear would do with prey), and a similar position of lying down.

I wonder what is the life span for a pizzly bear?

[Deleted]

My 2 cents a similar lifespan as the polar and grizzly bear given the fact these hybrids exist in the wild naturally.

[BruteStrength]

Probably since nature usually always correct things out.

[Deleted]

Agreed. Wild hybrids are healthier Tha ln captive hybrids. Grolar bears are healthier than captive born ligers. Cetaceans like blue whales and sperm whales and even son dolphins produce natural hybrids.

[BruteStrength]

Well we know that polar bear grizzly bear hybrids are much healthier than ligers and tigons.

Thats true. Like Bjorn said, bear’s hybrids are born naturally in the wild, so they are perfectly fine. Ligers are just born in captivity, not natural, so they have a whole host of problems.

I know you guys know. What I meant was its hard to find a healthy and fertile hybrid in general. Cetaceans in the ocean also produce healthy hybrids.

Don't asiatic lions share some range with tigers? Maybe they can breed in the wild.

No not really. Asiatic lions live in the gir forest but it the more open spaces while bengal tigers prefer the more forested areas. I have seen a poster named Royal Leo post an account of a tiger and lion which met in the forest and had a fight but both when their seperate ways but there is no record of them breeding. Only grolar bears as well as hybrid versions of blue and fin whales as well as some types of dolphins have been found in the wild naturally.

Lions and tigers, as I am led to believe, are natural enemies. They would rather kill each other than to breed. However, I have no idea how this might be known.

The problem is there are no records of bengal tigers and asiatic lions mating in the wild. Asiatic lions are very rare now. The mating always goes on in captivity.

All Im saying is didn't these 2 animal once share a domain? If a tiger and a lion once met then perhaps it's possible that they could have bred in the wild. Im not too sure about them breeding and producing offspring though.

I am not a hundred percent sure but brown bears don't breed with black bears in the wild even though they share a domain surprisingly.

[BruteStrength]

You make a very great point because black bears and brown bears can produce offspring but this never occurs in the wild, at least not that I know of.
