A couple of crested ibis takes care of their nestlings at Tianling Village of Yangxian County in Hanzhong City, northwest China's Shaanxi Province, June 2, 2018. The crested ibis were thought to be extinct in the wild until the discovery of seven wild crested ibises on May 23, 1981 in Yangxian, Shaanxi Province. After decades of conservation, the population of the endangered bird species has been growing. About 2,500 crested ibis live in Shaanxi Province. Their habitat covers around 14,000 square kilometers.
