Abstract
Baird's Sparrow is a migratory bird that has experienced a significant reduction in its populations. This study aimed to determine the size of the winter home range (WHR), population density, as well as seed biomass and soil cover and structure at three sites used by Baird's Sparrow and the relationship between these variables. The average WHR size was 0.042 hectares, with a seed biomass in the soil of 5.65 g/m² and a population density of 2.23 individuals/hectare. Significant correlations (Spearman, p≤0.05) were found between WHR and seed biomass, although these correlations varied between sites (DOWE rs=-0.90; LALA rs=-0.79; LAPO rs=-0.16). This study contributes to our understanding of the ecology of Centronyx bairdii. However, it is acknowledged that there may be other variables not considered in the study that could influence WHR.
