The major reasons for decline in the population of birds are: loss, modification, fragmentation and degradation of habitat, environmental contaminants, poaching, land use changes particularly conversion of large areas to intensive crop cultivation, changes in cropping pattern due to various reasons including implementation of irrigation schemes, increased pesticide usage and livestock-grazing, high levels of disturbance, developmental activities like mining and hydel projects. Threats posed by infrastructure development, such as collisions with vehicles, power-lines and wind turbines, further exacerbate the situation.
