The kissing is a bit much. But some exotic birds do learn it is a sign of affection and like it.
At the time of her death my Mom had 20 Exotic birds of various species: Mustache Parrot, dove, Cockatoos, MacCaws, other parrot types. Almost all rescues--the owner died and family didn't want--or the owner lost interest (they are a lot of work to keep healthy), or became abusive. Sometimes a Vet intervened.
The mustache parrot, Michael would drink out of her tea glass and got jealous if she was on the phone too long, squawking loudly till she hung up. One of the large parrots, Oscar, was so abused he did not trust men at all, but after months of work he trusted Mama, and the weeks i cared for him after her death he tolerated me cleaning his cage and food bowls. i felt awful when a falling out with my step-dad meant i had to abandon them all to his 'care'.
