Animal Behavior
AGGRESSION
Aggression in animals is when there is actual or potential harm to another animal or even human being. Animals often become aggressive when they fight over resources such as food and shelter. They also become aggressive when they are protecting their own and become territorial. They become aggressive with not only their own kind but others a well.
The Fight For Food
Vultures fight over access to carcasses. They are fighting for food and become more aggressive the hungrier they get. They attack each other by pecking, biting, wing pummeling and foot grappling.

Momma Bear
Female bears are often very aggressive towards other females and male bears when protecting their food territory for their cubs. Invaders are run off by the mother or sometimes they will take to a nearby tree with the cubs for safety sake.

Dogs Protecting Humans
A dog can be simply trained to be aggressive towards unrecognized humans and then tethered or enclosed unsupervised in an area the owner wishes to protect when he is not around. Aggression in dogs is sometimes a desired thing when used as a guard dog. Dogs aggressive behavior may include growling, barking, biting and attacking.

Harmless Behavior Leads To Aggression
A common feature of aggression in most species is fights start with a harmless display or posture. Stags begin with an exchange of deep roars followed by a display of “parallel walking,” where they strut side by side assessing their relative size. The aggression sometimes escalates to attacks during which the stags charge at each other, stabbing and wrestling with their antlers.
