印度研究人员的两项历时五年的独立研究显示，喜马拉雅地区的鼷鶟正在因人类活动而改变其鸣叫方式。1研究团队在印度北部喜马拉雅山脉的Uttarakhand和Himachal Pradesh两个邦的两个山谷中记录了超过700只鼷鶟的鸣叫声，其中第二项研究在2023年4月至2024年4月间进行。1
来自Hemvati Nandan Bahuguna Garhwal University的研究人员Dr. Rajeev Lochan、Dinesh Kumar Sharma和Anand Kumar发现，人类噪音直接影响了这种鸟类的交流方式。1在噪音较多的Chopta地区，鸟类产生的鸣叫声频率明显高于安静的Madmaheshwar地区的鸟类。1基础设施开发和旅游业正在压缩该鸟类的栖息地，增加的噪音迫使鸟类改变音调频率以进行交流。1
除了人类噪音的影响外，气候变化也在重塑这一物种的生活方式。1研究表明，气候变化导致该鸟类在山区不断向更高海拔迁移。1根据IPCC全球气候模型的预测，气候变化预计将在2100年前持续缩小并不稳定化该鸟类的栖息地。1
Indian researchers conducting two separate five-year studies have documented how a Himalayan bird species is fundamentally changing its communication patterns and habitat use due to human activity.1 The research, led by Dr. Rajeev Lochan, Dinesh Kumar Sharma, and Anand Kumar from Hemvati Nandan Bahuguna Garhwal University, analyzed vocalizations from over 700 birds across two valleys in the Himalayan regions of Uttarakhand and Himachal Pradesh in northern India.1
The studies revealed that infrastructure development and tourism are fragmenting the bird's natural habitat while simultaneously increasing noise pollution.1 Birds in noisier areas, particularly around Chopta, were found to produce calls at significantly higher frequencies compared to those in quieter zones such as Madmaheshwar, indicating a direct acoustic adaptation to environmental noise.1 Beyond shifting their vocalizations, the species is also migrating to higher elevations in response to climate change, with projections based on IPCC global climate models suggesting the birds' habitat will continue to shrink and become increasingly unstable by 2100.1
