Why they are not pelicans in Hawaii?

Pelicans are not native to Hawaii due to the islands' isolated location and unique ecological evolution. The absence of suitable nesting habitats and the specific dietary needs of pelicans may also contribute to their absence. Instead, Hawaii has its own unique bird species that have adapted to the islands' environments over millions of years. Additionally, the introduction of non-native species and habitat changes may further limit the potential for pelicans to thrive in Hawaii.
