birds evolved from earlier feathered dinosaurs within the theropod group, which are traditionally placed within the saurischian dinosaurs; their closest living relatives are the crocodilians.
Birds are often important to island ecology. Birds have frequently reached islands that mammals have not; on those islands, birds may fulfil ecological roles typically played by larger animals.
