Bugs represent the most serious cost of living together for cliff swallows, and we have studied their effects on the birds’ survival, colony choice, dispersal, nesting behavior, and physiology. We have used fumigation at some sites to remove bugs, enabling us to study how cliff swallows respond to their absence.
