Behavioural studies of the cockatiel species Nymphicus hollandicus are scarce in the literature.A better understanding of their behaviour in captivity is crucial for a better understanding of their physical and social needs, thus contributing to proper management in commercial breeding facilities, since the cockatiel is one of the most widely bred species of Psittaciformes in the world as a pet bird, as well as other species of psittaciformes, including endangered birds, thus aiding in fauna conservation projects and the breeding of psittaciformes in zoos. In addition, captive animals depend exclusively on man for their survival, so animal welfare becomes an indispensable element for a satisfactory quality of life in captivity.
