Population monitoring and modelling of yellow‐shouldered parrot on Bonaire, Caribbean Netherlands

Abundance estimates based on adequate survey design and count methodology are needed for population monitoring and modelling, and for assessing the results of conservation actions taken to boost or maintain population size at desired target levels. We monitored Bonaire's population of yellow‐shouldered parrot Amazona barbadensis rothschildi using systematic distance sampling surveys in 2009–2017, and developed a Bayesian state‐space logistic model to predict changes in abundance resulting from increased human‐induced mortality in 2018–2066. Survey‐based abundance estimates (mean ± bootstrapped... Mehr ...
