We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time

1. Dietary studies in birds of prey involve direct observation and examination of food remains at resting and nesting sites. Although these methods accurately identify diet in raptors, they are time consuming, resource intensive and associated with biases that stem from the feeding ecology of raptors like Gyps vultures (Gyps africanus and Gyps rueppelli). Our study set out to estimate diet composition in Gyps vultures informed by stable isotopes that provide a good representation of assimilated diet from carrion resources in local systems. 
2. We hypothesized that differences in Gyps vulture diet composition is a function of sampling location, and that these vultures move between Serengeti National Park and Selous Game Reserve to forage. We also, theorized that grazing ungulates are the principal items in Gyps vulture diet. 
3. Through a combination of linear and Bayesian models, diet derived from d13C in Gyps vultures consisted of grazing herbivores across study areas, with those in Se..., Data was collected for 10 months as a masters research project. Gyps vulture, herbivore muscle tissue samples were collected from two protected areas Serengeti National Park and Selous Game Reserve in Tanzania. Samples were then processed for stable carbon, nitrogen and sulfur isotope analysis. Statistical analyses on stable isotope data, were carried out in R to inform Gyps vulture diet over space and time. , Coordinates have been denatured by +0.5 degrees to preserve the integrity of the overall geographic distribution but ensure confidentiality., # We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time
