Density-dependence of nestling immune function and physiological condition in semi-precocial colonial bird: a cross-fostering experiment
Abstract Roper Style Saddle Background Nesting in large aggregations provides several important advantages for colonially breeding birds.However, it also imposes certain costs, associated with facilitated pathogen transmission and social stress.The cost-benefit ratio is not similar for all the birds in a colony and it might be mediated by nest dens
