Photo of the Day #146: Playing Polar Bear

During most of my visits to the Bronx Zoo, the polar bear (Ursus maritimus) is usually sleeping or too hot to move around much, but yesterday she was in a much more playful mood. While they certainly are powerful predators, polar bears can be quite playful, and during the winter adult males sometimes play with dogs in the wild. Very little seems to be known about why polar bears and dogs get along during this time of the year, but for whatever reason there is little tension in what otherwise might be an antagonistic confrontation.

The brown bear (Ursus arctos) is the second largest living bear (the largest being the polar bear, Ursus maritimus), but depending on where you are in the world it can go by many names and vary in appearance. At present there seems to be a glut of possible brown bear subspecies that scream for…
In most zoos and animal parks, polar bears (ursus maritimus) attract such a disproportionate amount of attention that they are referred to in the industry as "charismatic megafauna," or in other words, "really cool animals." Perhaps it is because it is especially rare for the average zoo-goer to…
Throughout most of the world humans have exterminated carnivores in order to keep their places of habitation safe, and while large carnivores still exist in patches we have a sort of "You keep to your side, I'll keep to my side," sort of attitude towards them. The problem, however, is that we keep…
This is from Seabeck, Washington, across the water from Seattle. Ursus americanus is one of those species with a LOT of variation in adult body size. Males can run from 46 to 409 kg (100 - 900 lbs) [ADW], with the average around 100 - 120 kilos. Record size black bears include: North…

That's a fantastic photo, Brian. Next time you're thinking of visiting the Bronx zoo, will you let me know? I've never been.

Omigod, that video of the polar bears and the dogs is too cute!

The polar bear in your photo looks like she's playing with a bowling ball? She actually looks like a big puppy who's found some water to play in.

How do they keep the polar bears cool in the summer? It must be terribly hot for them.

Melaine; Sure thing! You'll love it (especially in the springtime when the gorillas are outside).

Elisabeth; It wasn't a bowling ball, but it was something similar. She really loved it, and I have a whole sequence of her playing with it. She's old (you can can tell she's a bit grizzled and has a cracked front lower canine in the photo) but she was very lively yesterday.

From what I can gather the pool is kept cold and there are artificial rocks in the exhibit that are kept cool (just like others are kept warm for other animals this time of year). It's still awfully hot for this bear, though, and the ones at the Central Park and Philadelphia zoos also become very lethargic in the summer due to the heat & humidity.
