Input data, NIMBLE code, and MCMC summary and visualization code for "Reproductive failure and adult mortality drive viability of an endangered songbird population, not brood parasitism"

The pva_code.r file loads the pva_input.rda data file, creates a NIMBLE model, builds, and runs the model, indexes, and saves the MCMC output. The script can be run in parallel without overwriting outputs. The pva_analysis.r file then reads the outputs, checks for model convergence, generates the test quantities, and creates the MCMC summary statistics and visualizations.Figure S1 shows low and stable estimated numbers of immigrant female chats given our model, supporting the conclusion that immigration did not contribute substantially to population dynamics of the Southern Mountain population of the Western Yellow-breasted Chat (Icteria virens auricollis) in our study area between 2002 and 2021.
