A beautiful Himalayan bird is changing its voice due to human activity, research shows
A sharp increase in human activity is affecting the way the Himalayan monal lives and communicates, studies show.
Two studies by Indian researchers have revealed that human activity is altering the behavior and communication of the monal, a striking pheasant found in Himalayan mountain forests. The monal, a cultural icon in both India's Uttarakhand state and Nepal, is facing threats to its habitat and communication as infrastructure development and tourism surge.
One study found that monals are compelled to move to higher elevations due to overcrowding in alpine meadows above the tree line, while another study discovered that the birds are adjusting their vocal pitch to overcome background noise in densely populated valleys. These findings highlight the potential impacts on other species within the fragile ecosystem.
