A national nature reserve in Nenjiang, northeast China's Heilongjiang Province, has recorded repeated sightings of the black-billed capercaillie, a first-class state-protected species – signaling a steady population recovery and improving habitat. Footage shows males puffing up and producing deep, resonant calls, not to sing, but to compete for mating rights – while females watch quietly, choosing the strongest partner.
