While the Grants were on the Galápagos, a drought occurred. As a result, fewer seeds were available for finches to eat. Birds with smaller beaks could crack open and eat only the smaller seeds. Birds with bigger beaks could crack and eat seeds of all sizes. As a result, many of the small-beaked birds died in the drought. Birds with bigger beaks survived and reproduced (see Figure below ). Within 2 years, the average beak size in the finch population increased. Evolution by natural selection had occurred.
Consider the following text:
Two islands inhabited by many species of finches went through some climatic changes during the past several years. While Park island hat wetter than average years, Boat island experienced years of drought, so many birds died.

Which island had fewer large-beaked birds reproduce?
