Data from: Spatial and temporal unpredictability of colony size in cliff swallows across 30 years

Charles R. Brown, Mary Bomberger Brown & Erin A. Roche
Most colonially breeding animals occupy colonies that range in size from a few pairs to thousands of individuals, but the causes of colony size variation are largely unknown. Three general hypotheses are: (1) that variation in colony size is maintained by fluctuating selection via spatial and temporal changes in fitness associated with different colony sizes; (2) that colony formation reflects heterogeneity in habitat, with some sites having resources to support more individuals than others; and...
