American white pelican predation on adult sockeye (2014-2023)

Adult Sockeye Salmon (Oncorhynchus nerka) migrate through the area of the Columbia River, USA, home to the largest breeding colony of American White Pelicans (Pelecanus erythrorhynchos). To assess the extent of pelican predation on these salmon, a state-space Bayesian model was employed, estimating predation and survival probabilities with spatial and temporal detail, as well as the annual total of salmon consumed by pelicans. This dataset includes capture-recapture-recovery data, adult salmon counts, and the model code used to generate the predation probabilities, survival probabilities, and yearly estimates of salmon consumed by pelicans.
