Experimentally broken faecal sacs affect nest bacterial environment, development and survival of spotless starling nestlings [Dataset]

Nestlings of most avian species produce faecal sacs, which facilitate the removal of nestlings’ excrements by parents, thereby reducing proliferation of potentially pathogenic microorganisms and/or detectability by predators and parasites. The nest microbial environment that birds experience during...
