Jaya Guru Datta,
Who taught man to speak, who taught him to sing, who gave the man idea to fly, who pointed him fruits on branches of trees, Birds is the answers one always get :-) these birds are not just another creatures living along but are teachers and still lesson is still long, Swamiji that's why started an aviary very close to himself so that not just his followers but whole world can get a chance to know more from the parrots.
Sri Guru Datta
