Growing human activity is affecting both the habitat and calls of the Himalayan monal, according to two studies. The research reports that the bird’s habitat is shifting to higher elevations, while noise in tourist areas is associated with changes in the pitch of its call.
Increased vehicle traffic and human noise are identified as factors linked to the change in the monal’s voice. The findings point to broader effects of human activity on the bird’s living environment and communication.
Human noise linked to changes in the monal’s call
The studies report that the Himalayan monal has altered the pitch of its call in areas affected by noise from vehicles and people. The findings do not specify the direction or extent of the pitch change.
Habitat shifting to higher elevations
The research also reports that the monal’s habitat is moving upward. Together, the findings show changes in both where the bird lives and how it calls as human activity grows.
