The birds exhibit following behaviour:
(1) They produce peculiar sound and communicate with each other by song and bird calls.
(2) Several species exhibit courtship in the form of mating dance.
(3) Nest building is peculiar instinct in many birds, e.g., Male weaver and Tailor bird.
(4) Most of the birds show parental care. The parent guard and sit on the eggs till they are hatch and look after their young ones till they get independent.
(5) Bird migration is another surprising behaviour.
