Do birds fly from the mainland to Hawaii?

Yes, birds fly from the mainland to Hawaii. Many bird species, including several endemic species, migrate between the mainland and Hawaii. For example, the iconic Hawaiian goose, or nene, migrates from the drier areas of the main islands to the lusher subalpine regions of Mauna Kea during the winter months. Other birds that migrate between the mainland and Hawaii include the endangered Hawaiian stilt, the Pacific golden plover, the ruddy turnstone, and several species of albatrosses and shearwaters.
