Document Summary
Male white-crowned birds sing their own distinct song. According to a hypothesis, their song would be instinctive behaviour, one genetically or developmental programmed that appears incomplete and functional from the 1st time it is used. Also might be learned behaviour, one that depends on having a particular kind of experience during development. If its instinctive, isolated male nestlings that have never heard other members of their species should be able to sing their species" song when they mature. Instinct: can presumably be performed without the bene t of previous experience and can be grouped into feeding, defence, mating, and paternal care. Assume they have a strong genetic basis and natural selection has preserved them as adaptive behaviours. When an animal is triggered by a speci c cue, it performs the same response over and over in almost the same way: xed patterns and triggered by sign stimuli.
