Interspecific variation in shorebird population trends in relation to migration stopover habitat

This repository contains data and R code used to estimate population trends of migratory shorebirds wintering in Bangladesh and to examine ecological and phylogenetic predictors of interspecific variation in those trends -- accepted for publication in Proceedings of the Royal Society B (2026). The dataset includes site-level count data, species-level trait information, phylogenetic inputs, tracking data and mainland China eBird checklist summaries used in the analyses. The R scripts reproduce all statistical models, tables and figures presented in the manuscript including population trend estimation, model comparison, bootstrap uncertainty, interspecific regression analyses and phylogenetic modelling. All files are organised to allow full reproducibility of the analyses from raw data to final outputs.
