MERLIN 技術支援

Large tern, found strictly in coastal areas. Feeds in open ocean and saltwater bays, where it flies high above the water looking for small fish. Rests on beaches, often in groups with other species. Separated from many terns by large size; only slightly smaller than Caspian. Look for the thinner orange bill (usually not deep red) and shaggier crest compared with Caspian. Also, forehead whiter than Caspian Tern in the nonbreeding season; this can show as early as midsummer.
