Parrots are highly intelligent and powerful flight animals with complex needs. Why breed such a bird when its life is to be one of a captive, to be treated as a trinket for our amusement. Breeding a bird to live in a cage is not loving it, it is controlling it and depriving it of its innate needs.
The selling of these birds in markets and festivals is irresponsible because the display of these caged birds acts as a novelty that encourages impulse buying and publicly endorses the idea that the practice of caging animals is an acceptable one.
