A beautiful Himalayan bird is changing its voice due to human activity, research shows

A sharp increase in human activity is having an impact on the way a Himalayan bird lives and communicates, two studies by Indian researchers have found. The monal, a pheasant native to Himalayan mountain forests, is deeply woven into the region's cultural, folklore and identity. The eye-catching monal - the male has distinctive green, blue and copper feathers - is the state bird of India's Uttarakhand state and the national bird of Nepal, reflecting its cultural significance across the Himalayas. But studies show that infrastructure development and tourism are squeezing its habitat, while increasing noise is altering how it communicates with potential mates and rivals.
