It must be the right thing to do. And it makes us feel better too. Comforting and soothing a parrot is one way to help develop them to their full potential. In the wild and in our living rooms, birds sing. Their instinct is to sing or call or screech as some people say, but it is melodic and it is song under another name.
Parrots also sing alone.
Their singing celebrates their happiness, relieves their boredom and stress, and is a way of entertaining themselves like playing with toys. This picture is of my Moluccan singing an off-key version of Row Row Row Your Boat. In summary, singing songs to your parrot contacts them, contacts us, brings them comfort, signals events like night night, helps them bond, enhances joy of life for both the parrot and us, and restores order to their sometimes jumbled day. You are a parrot keeper. You are charged with an awesome responsibility to produce the best companion parrot you possibly can.
