Abstract

Lay SummaryExtravagant seasonal male ornaments are assumed to be sexually attractive. Fairy-wrens are a well-known example, where females cheat on their mates by copulating with attractive males that produce ornamental plumage early in the year. Purple-crowned fairy-wrens lack this extreme infidelity, but males do produce a conspicuous breeding plumage at highly variable times. However, this does not appear to bring any fitness benefits or costs, and the stunning purple crown might disappear over (evolutionary) time.Twitter: @colourfulmarie
