Black-necked cranes filmed in highland nature reserve

(ECNS)--An expert team recorded videos of black-necked cranes in Selincuo National Nature Reserve during a 10-day research trip.

The black-necked crane, the only crane to inhabit highlands, is as precious as the giant panda.

With an estimated population of around 10,200, the species is classified "vulnerable" by IUCN and listed among over 90 endangered species on China's top protection list.
