From July 2010 to January 2011,scan sampling and behavioral sampling methods were used to study the behavior of Crested Ibis (Nipponia nippon) in Yangxian Crested Ibis Acclimation Park (n_YX=30) and Huayang Crested Ibis Acclimation Base(n_HY=22).The acclimation conditions of the two training cages were also compared.The results indicated that the time budget of foraging behavior were significantly different in the two training populations.In autumn,the Yangxian birds showed more paddling,explore pecked,biting throw and washing food behaviors(P<0.01),while the searching and filter pecked behaviors were significantly less than what of the Huayang birds(P<0.01).There was no tearing food behavior in Huayang.In winter,the foraging behavior differences were similar to what in autumn,however,there was more hollow-out behavior in Yangxian birds(P<0.05) and there was no paddling,tearing and biting-throw food behavior in Huayang birds.In Huayang training cage,the Crested Ibis frighten-flying time (96.5±84.9 s) was significantly longer than what of the birds in Yangxian cage (40.6±51.3 s),and the landing site tendency was also different.From July to mid December 2010,some of the birds in Huayang showed abnormal behavior of roosting on the ground at night.The shape of the food and the foraging site quality in the training cage were main factors caused the foraging behavior difference.The frighten-flying time and landing site tendency of the ibis maybe related to the shelter abundance and openness of the training cage.The shortage of perch in Huayang cage caused some birds' abnormal behavior of roosting on the ground.
