Size, not color, drives assortative mating and influences fledging survival, weight and immunity in a polymorphic owl

Abstract The persistence of color polymorphism in nature may be driven by disassortative mating based on color. In vertebrates, body size sometimes correlates with coloration, complicating mating patterns, as the selective pressures favoring mixed-color pairs might be counterbalanced by those influe...
