Two tiger calves, seven baby sika deer and 20 ostrich chicks made a collective debut at the Kunming-based Yunnan Wildlife Park on July 29, impressing the visitors a lot.

　　“The twin of Manchurian tigers and the sika deer are almost two months old now, and the ostrich chicks are growing well,” said Liu Dongmei, a staff member at the Yunnan zoo.

　　Liu added that the baby animals have gone through the adaptive phase, no long afraid of meeting strangers. On the occasion of the coming COP15 in Kunming, Liu called on more public effort in protecting wild animals.
