Demography and Populations

Based on transect counts in a study area at Atitlán volcano, density in broadleaf forest was 56 birds / km2 (95% confidence interval: 33-93 birds km2). Broadleaf forest covers approximately 250 km2 of the entire potential area of distribution of Azure-rumped Tanager in Guatemala. Assuming that the density of Azure-rumped Tanagers in all broadleaf forests is similar to the value determined in the study area at Atitlán volcano, the total population of Azure-rumped Tanagers in Guatemala is estimated to be 8250-23250 birds (Eisermann et al. 2011a). No recent estimates are available for Chiapas. Age at first breeding, life span and survivorship, diseases and body parasites, and dispersal remain unknown.
