HEAD‐SCRATCHING IN THE PSITTACIFORMES

They make it possible to describe behavioural repertoires and their occurrence in different contexts accurately. As there is no standardised ethogram for Psittaciformes in the scientific literature, this study aimed to create one by compiling information from ...

Nutrition of Birds in the Order Psittaciformes: A Review

Journal of Avian Medicine and Surgery, 2001

Longevity records for Psittaciformes in captivity

International Zoo Yearbook, 2000
Psittaciformes are generally believed to be long‐lived birds and are frequently said to reach ages of 100 years old or more. In reality, however, life spans rarely exceed 50 years of age, although a few reliable records exist of parrots aged up to 65–70 years.
