The zoo says it was just an accident because this bear likes to play with large rocks.
Brown Bear Tool Kit: A Rock for Scratching
An observation of a bear using a rock as a scratching tool surprises scientists.
Thus it appeared that not just any rock would do, it had to be covered with barnacles which would do a better job in scratching. It wasn’t just a fluke either. After a while, the bear dropped the rock, moseyed around, and after some time searched for and retrieved another rock. In all the bear repeated the whole exercise three times, retrieving three different rocks, all covered with barnacles, which he used for scratching at his itchy hide. Deecke also noted that the bear manipulated the rock in his paw before scratching, moving it into the optimal position for the best possible scratch, a type of activity previously only seen with humans and other primates.
Deecke suggests that more research ought to be focused on bears because clearly they are capable of far more than has been realized.
To do this, the dolphins swim in circles near the marsh banks and then switch up the pace and swim up onto the marsh. In doing this, they create a bow wave that sends all the little fish in the area up onto the marsh so that the semi-beached dolphins can gobble up the dumbstruck fish. (The marsh birds take advantage of this as well and swoop down to catch the unsuspecting fish).
After the dolphins have their fill, they slide back into the water and gear up to do it again.
What’s most interesting about strand feeding is that it isn’t something that dolphins are meant to do; it’s something they learned to do. The intelligence of these aquatic mammals has long been something marine biologists have marveled over, and this form of fishing is just another example of how smart dolphins are.
