Experimental modification of bacterial densities in nests and on feathers. Full circles represent the total cultivable bacterial densities, empty circles the keratinolytic bacterial densities (a: nests; b: plumage; mean ± SE of log transformed CFU). Bacterial densities on adults from the two sexes were not differently affected by the treatments (treatment * sex interactions, all P > 0.05).
