and this :
Here's he proof you wanted!
a vet wrote this:
"Many psittacine owners observe behaviors that range from cute to puzzling. These may in-clude intense bonding, constant egg laying, paper shredding, cavity seeking, loud vocalizations or fierce territoriality. In some instances, these behaviors may occur seasonally and have little impact on the bird's general health. In other cases, these behaviors progress from seasonal to year round and can have a very serious impact on the bird's health. Some of these behaviors, like protracted egg-laying, are obviously driven by reproductive hormones. A myriad of other behaviors, some subtle and some puzzling, may also be related to reproductive hormonal events."
Here is another source (quoting a doctor)
https://summer2018.iaabcjournal.org/...nion-parrots/:
"Dr. Sharman Hoppes also draws this link between diet and behavior: “Behavioral problems that can be related to reproductive issues include feather picking, mutilation, and excessive screaming. These behaviors can also occur for other reasons, so a full evaluation must be done to determine the cause. Behavioral problems are most common in hand-raised parrots overly bonded to their owners.” She continues: “In captivity, most pet birds are kept all year at stable temperatures and are provided adequate food, which is often high in fat. This can promote breeding behavior year-round.”
and another:
"While these behaviors may happen only seasonally in the beginning, they can progress in some individuals until they occur year round. In many cases, they lead to problems such as feather damaging behavior, self-mutilation, regurgitation of food, masturbation, chronic egg-laying, egg binding and cloacal prolapse. It is not unusual for these behaviors to surface when the parrot is well into adulthood, often coming as a surprise to the owner who has come to take for granted more stable conduct."
and another
"Domestic parrots tend to have completely different environmental and lifestyle experiences than their wild cousins, resulting in physical and behavioral problems. Caretakers innocently make decisions that mess with the birds’ sexual hormones. Case in point: expecting your parrot to adapt to your sleep cycle when parrots actually need 10-12 hours of sleep. Couple lack of sleep with other lifestyle and environmental stressors (diet, improper petting, a sedentary lifestyle, or access to nesting materials) and the effect on their body and behavior can be major. We call this a chronically hormonal state and it has unhealthy consequences for your pet"[/B][/I]
and another:
.... behaviors that often result from such a diet include: intense bonding with one person in the family,
cavity-seeking behavior, paper shredding, loud demanding vocalizations, and fierce territoriality. While
it may be cute initially when a parrot becomes obsessed with getting into dark drawers or closets, or
wants to be with us constantly, these behaviors over time become problematic. And, while these
behaviors may occur only seasonally in the beginning, they can progress in some individuals until they
occur year round, developing into problems such as feather picking or feather barbering, self-mutilation,
chronic egg-laying, egg binding and cloacal prolapse
This is me ( the rest were vets)--in a house where hormonal triggers are well-controlled and sleep is regulated, you are more likely to see your clock-work, 2x yearly hormones..and certain species are worse than others about raging "off the clock", but ANY parrot can get hormonal at ANY time if the setting is conducive
