The term 'predatory seabird' encompasses four different species: the ern (3 letters), JAEGER (6 letters), SKUA (4 letters), and ERNE (4 letters). The ern is a small, stocky seabird that feeds on fish and insects. The JAEGER is a medium-sized seabird that hunts other birds and small mammals. The SKUA is a large, aggressive seabird that feeds on fish, eggs, and carrion. Finally, the ERNE is a large, powerful seabird that feeds on fish and other seabirds. All four of these predatory seabirds are found in coastal areas around the world.
