Conducta de alimentación de cinco especies de cotorritas (Aves, Psittacidae)

Resum

Feeding behaviour of five species of Parrots (Aves, Psittacidae)
The feeding behaviour of some captive parrots belonging to the species Aratinga aurea, Myiopsitta monachus, Nandayus nenday, Orrhura molinae and Brotogeris versicolorus is investigated. Three factors and their inter-relations ate anaiyzed: Type of feeding (beak o1 feet), Manipulation (left or right foot), and Localization (ground or higher level). Parrots preferentiy take food with the beak. When manipulating food, specific preferences for left or nght foot are detected. Independentiy of the species the parrots manipulate food with their nght foot when on the ground, and with the left one when on a higher level. Parrots adapt their behaviour to captivity.
