Coloniality in the Cliff Swallow
The Effect of Group Size on Social Behavior
Drawing on their twelve-year study of a population of cliff swallows in Nebraska, the Browns investigate twenty-six social and ecological costs and benefits of coloniality, many never before addressed in a systematic way for any species. They explore how these costs and benefits are reflected in reproductive success and survivorship, and speculate on the evolution of cliff swallow coloniality.
This work, the most comprehensive and detailed study of vertebrate coloniality to date, will be of interest to all who study social animals, including behavioral ecologists, population biologists, ornithologists, and parasitologists. Its focus on the evolution of coloniality will also appeal to evolutionary biologists and to psychologists studying decision making in animals.
