<p>This paper presents the documentation of the four-horned antelope (Chousingha) in the Gautam Buddha Wildlife Sanctuary for the first time. This record is based on our observation throughout the protected area as a part of the Environmental Impact Assessment (EIA) study during 2019-2020. Although the species has a pan-India distribution, the correct estimate of the population is unknown. As the number of this schedule-I species is continuously decreasing this documentation provides a way to conserve and retain the population in this protected area.</p>
