Climate change, largely driven by the rapid rise in greenhouse gas emissions, is now widely recognized as a major force reshaping ecological systems around the world. One of the clearest signs of this transformation is the noticeable shift in bird migration patterns, particularly among species that travel long distances. This study explores how unusual changes in temperature and rainfall are influencing migratory bird behavior in Bharatpur, a renowned wetland region in India. Using a combination of firsthand insights from local communities and sanctuary staff, along with official climate data from the Indian Meteorological Department (IMD), the research follows a mixed-method approach. Fieldwork, ecological monitoring, and statistical analysis were conducted to better understand these dynamics. The results show a clear decline in the arrival of iconic species, such as the Indian Sarus and the Siberian Crane, which is linked to irregular rainfall and warmer winters. Changes in seasonal timing, such as earlier blooming of plants and insect emergence, are also creating mismatches with bird breeding periods, resulting in food shortages for chicks. The study also notes that while monsoon rains tend to support crane populations, excessive winter rainfall may have the opposite effect. In addition to climate pressures, human-related challenges such as shrinking habitats and the spread of invasive species are further endangering these migratory birds.
