That’s pretty weird and fascinating at the same damn time
Parrots pair up with a mate during breeding season and if your bird doesn’t have another parrot to fall in love with, he just might fall in love with you. Parrots that are never exposed to other parrots during childhood can become sexually imprinted to humans which means that they will think they are supposed to mate with people and can actually reject other parrots as potential mates.
If your bird falls in love you, he (or she) may become extremely aggressive toward other people and may do strange things with you. Love struck parrots regurgitate food and offer it for you to eat, they may also try making love with your hand or pressing their back up against you inviting you to mate.
This is truth.
