What birds demonstrate adaptive radiation?

Answer 1

Adaptive radiation is prominently demonstrated by the finches of the Galápagos Islands, often referred to as "Darwin's finches." These birds evolved from a common ancestor into multiple species, each adapting to different ecological niches and food sources on the islands. Other examples include the cichlid fish in African lakes and the Hawaiian honeycreepers, which also showcase diverse adaptations to varied environments and diets.
