Abstract
Understanding wildlife behavior, including accurate identification, processing, and interpretation of activities or cues, is important to behavioral biology and corresponding conservation strategies. We characterized the breeding activities of the critically endangered White-rumped Vulture Gyps bengalensis following a sequential pattern from courtship to fledging. We recorded 4,160 visual observations of 20 behaviors of eight pairs of White-rumped Vultures from September 2021–April 2022 and constructed Markov chain models to model three composite behaviors (i.e., breeding, foraging, and roosting). We found that vultures at four nests displayed >70% of the time in breeding behavior, and each nest produced offspring, indicating a potential correlation between breeding behavior and successful reproductive outcomes. Our model explained each composite behavior with high accuracy. Identifying behaviors White-rumped Vulture have practical applications for developing management plans for their conservation, including the timing of critical reproductive events. Our findings and approach can improve our understanding of White-rumped Vulture behavioral ecology and conservation and have applications for other species.
