Document Summary
Instinct: a behaviour pattern that reliably develops in indu. That receive adequate nutrition and that is given in functional form on its first performance. Learning: a dura(cid:271)le a(cid:374)d usuall(cid:455) adaptive (cid:272)ha(cid:374)ge i(cid:374) a(cid:374) a(cid:374)i(cid:373)al"s (cid:271)ehaviour tra(cid:272)ea(cid:271)le to e(cid:454)perie(cid:374)(cid:272)e by that individual: pink cckatoo and galah bird may lay egg in same nest. Then cockatoo will have egg from both birds. Call types: begging calls- begging for food from parents, alarm calls- given in presence of predator, contact calls- maintain associations with parents/flock when mobile. Results of a natural experiment: galah chick raised by pink cockatoos, will have galah begging call even though raised by cockatoo, galah learned contact call from cockatoo. Types of learning: habituation: repeated stimulae without appropriate feedback or unimportant stimulae (idle threats) Imprinting: structured learning- critical periods, life long learning- often involves mating: chick wont duck down for harmless stimulae, children imprint on first thing they see, associative learning: association of stimulae.
