The observed bird counts at both the forest and grassland sites A, with differences in community composition displayed in a non-metric multidimensional scaling graph B based on a Bray–Curtis presence/absence distance matrix (linear fit R² = 0.986, non-metric fit R² = 0.997). The ratios of observed birds at grasslands and forest patches that are sedentary birds, short-distance migratory bird and long-distance migratory birds C
