Black-necked cranes in Tibet, "We are hatching babies"!

Black-necked cranes are a national first-class protected wild animal, belonging to the plateau-specific crane species, mainly inhabiting plateaus at altitudes of 2500-5000 meters, usually living in wetland environments such as marshes, lakes, and river beaches. At this time of year, pairs of black-necked cranes migrate to Shenzha County, Naqu, Tibet, and nest on the wetland grass mounds surrounded by water to hatch their eggs. Black-necked cranes usually lay 1 to 2 eggs per nest, with an incubation period of about 30 days. Experienced wildlife rangers can estimate the hatching time of the chicks through the patterns and colors on the eggshells.
