I know it sounds obvious, but it’s not. Probably 90% of the parrot behavior problems I address are due to hormonal behavior, often stimulated by their owner petting and cuddling them like a dog. Cockatoos are especially susceptible because of their love of touch. Improperly touching your bird can degrade your relationship and cause aggressive behavior, egg binding, territoriality, health problems, and general bad attitude. I’m not saying don’t touch your bird – that would be miserable for both of you – I’m saying do it properly! Please email me to learn how to interact in a friendly, but appropriate way with your bird!
