A study of more than 2,000 bird species shows that diversity in bill shape expands towards extreme morphologies early in avian evolution in a series of major jumps, before switching to a second phase in which bills repeatedly evolve similar shapes by subdividing increasingly tight regions of already occupied niche space.
