Here, the authors describe a complex pattern of within-individual flexibility in house sparrow clutch size. Particular aspects of flexibility vary among populations, but not as predicted by life-history theory. This has implications for understanding plasticity in life-history traits in general, and hypotheses about clutch size in particular. Photo credit to H. Jensen.
