Description
I have put together the most interesting behaviours about how brown bears feed on salmon into this infographic. I talked about how the size and sex of the salmon played a role in the brown bear's behaviour, how the bears acted with different abundances, how dominance plays a role and some other interesting behaviours such as nocturnal fishing. Brown bears have developed these techniques to get the maximum efficiency when they are fishing, making this a very interesting topic to learn about.
