The effects of environmental enrichment on the behaviour of cockatiels (Nymphicus hollandicus) in aviaries
Most research to enrich the environment of psittacines in captivity has focused on foraging. Little is known about the importance of bathing substrates for enrichment of their environment, despite this being a natural behaviour that is rarely possible in captivity. Twelve captive-bred, adult cockatiels (Nymphicus hollandicus) were housed in groups of four in three aviary […]

Excretion and metabolic fate of radiolabeled estradiol and testosterone in the cockatiel (Nymphicus hollandicus)
Abstract 10.1002/(SICI)1098-2361(1997)16:63.3.CO;2-Z The metabolism and time courses for clearance of radiolabeled estradiol and testosterone were studied in the female cockatiel (Nymphicus hollandicus) using a simple technique of solubilizing dried fecal/urine matter in an aqueous solution. Carbon 14 radiolabeled estradiol and testosterone were injected intramuscularly and the urine and fecal matter collected for the pursuant 168 […]
Environmental enrichment on the behavior and welfare of cockatiels (Nymphicus hollandicus)
This study evaluated the influence of physical environmental enrichment on the behavior of cockatiels (Nymphicus hollandicus). Eighteen birds, nine males and nine females, were monitored in environments enriched with wooden sticks and bead rings and in non-enriched environments, in a completely randomized design. Behavioral categories were grouped into locomotion, maintenance, rest, feed, undesirable activities, and […]
