Comportamento de calopsitas (Nymphicus hollandicus) mantidas em cativeiro sob duas temperaturas e enriquecimento ambiental ; Behavior of cockatiels (Nymphicus hollandicus) kept in captivity under two temperatures and environmental enrichment.
The aim of this study was to evaluate the influence of environmental enrichment and elevated temperature on the behavior of cockatiels (Nymphicus hollandicus) kept in captivity . Sixteen cockatiels were housed individually in cages and fed commercial diets for parrots and seed mix, with water provided ad libitum. Under these conditions , two experiments were conducted . In the first experiment , we assessed the effect of temperature on the behavior of birds . The experimental period of eight days , divided into two steps of four days each. In the first step , the birds were kept at 25 ° C duri... Mehr ...

The aim of this study was to evaluate the influence of environmental enrichment and elevated temperature on the behavior of cockatiels (Nymphicus hollandicus) kept in captivity . Sixteen cockatiels were housed individually in cages and fed commercial diets for parrots and seed mix, with water provided ad libitum. Under these conditions , two experiments were conducted . In the first experiment , we assessed the effect of temperature on the behavior of birds . The experimental period of eight days , divided into two steps of four days each. In the first step , the birds were kept at 25 ° C during the day and night , and in the following step at 35 ° C during the day ( 6:00 to 18:00 ) and 25 ° C at night (18:00 06:00 ) . The relative humidity was 70 % . The behavior of the birds was assessed by filming from 6:00 to 18:00 with camcorder . To be subjected to elevated temperatures ( step 2 ) , were not observed ( P > 0.05 ) changes in undesirable activities , however, the birds showed ( P < 0.05 ) higher feed intake , more time spent on the perch and smaller in ground and stayed asleep longer , and occurrences of birds flapping or biting the pot supply. In the second experiment , the animals were divided into two groups , control and enriched with eight birds each , all placed in a climatic chamber at temperature of 35 ° C from 06:00 to 18:00 h and 25 ° C from 18:00 to 06:00 , relative humidity of 70 % . The experimental period was 12 days , divided into three steps every four days - before, during and after the use of enrichment. Environmental enrichment was made with cabbage stalks and behavior assessed by filming . There were no behavioral differences ( P > 0.15) between control and enriched . During the enrichment step , all birds (control and enriched ) showed (P < 0.01) increase of body surface temperature which remained elevated after removal of enrichment. It follows that increasing the temperature from 25 to 35 ° C decreases the movement of the birds , but does not increase activities classified ...
