Indian Vultures (Gyps indicus) are critically endangered, yet are poorly monitored. We analyze counts of breeding pairs of Indian Vultures in Central India, specifically the eastern portions of the Indian states of Rajasthan and Madhya Pradesh over a period of 10 years and reveal the populations were on differing trajectories from 2007–2016. Indeed, the difference between population levels of the study areas nearly doubled during our study, with the population in Rajasthan falling relative to Madhya Pradesh. Future research should examine potential drivers of population declines and establish a long-term monitoring program that informs current conservation strategies for Indian and other vultures across their range.

印度相邻州的两个研究点之间的印度秃（（Gyps indicus）数量对比趋势

印度秃鹰（Gyps indicus）处于极度濒危的境地，但监控不力。我们分析了印度中部，特别是印度拉贾斯坦邦和中央邦的东部地区在过去10年中繁殖的成对秃鹰的数量，并揭示了2007-2016年期间种群的变化轨迹。实际上，在我们的研究中，研究区域的人口水平之间的差异几乎翻了一番，拉贾斯坦邦的人口相对于中央邦下降了。未来的研究应检查人口减少的潜在驱动因素，并建立长期的监测计划，以为印度和其他秃鹰在其范围内的当前保护策略提供依据。
