TYPES OF BEHAVIOR
Section 36.2
CATEGORIES OF ANIMAL BEHAVIOR
1. Foraging – locate, obtain, consume food
2. Migratory – move to a more suitable environment as seasons change
3. Defensive – protect from predators
4. Territorial – protect a resource for exclusive use
5. Courtship – attract a mate
6. Parental care – ensure survival of young
COMMUNICATION
Animals use signals to influence the behavior of other animals
Social animals – those that live in groups – have many forms of communication
There are different signals for different social situations
The signal must be something that can be easily sent and received
PRIMATE COMMUNICATION
Vocal communication is most developed in primates
Many have different sounds (‘words’) for different predators
Human language development begins at an early age – a child learns the language it hears spoken
Other forms of communication – body language – are also important
REPRODUCTIVE BEHAVIOR
Each species has a unique courtship signal – prevents mating with the wrong species
Mate choice – in most animals the female evaluates a mate before choosing
The female has a higher ‘stake’ in the choice – more energy to have babies & care for them
Sexual selection – the mate is chosen based on a certain trait – fancy tail feathers in male birds
In some species the males compete with each other –often to select the strongest
