Discussion Powerful, stocky seabird with broad, long wings and direct flight. Adult has diagnostic twisted, spoon-shaped extensions to central tail feathers. Latter feature, and larger size, allow separation from daintier Parasitic Jaeger. Harasses other seabirds into regurgitating previous meal, and sometimes kills smaller birds. Sexes are similar, but adults occur in two color morphs.
