Parasitic Jaeger

by | Jun 14, 2022

Parasitic Jaeger Stercorarius parasiticus

Texas Coastal / Offshore Status:  Uncommon migrant, rare winter resident and very rare in summer in offshore waters. A rare migrant and very rare winter visitor on the immediate coast. 

Habitat: coastal and offshore waters. May be seen chasing gulls and terns along jetties or near shrimp boats.

Similar Species: Very similar to Pomarine Jaeger. Identification difficult. Parasitic is more slender bodied than Pomarine Jaeger, having a relatively shorter and thinner bill. The tail and underwing coverts on Parasitic Jaeger are duller than the (boldly patterned) Pomarine and Long-tailed Jaegers. This feature creates little contrast between the underwing coverts and the flanks. The central tail feathers on adult birds are pointed, unlike the round and twisted tail feathers of Pomarine Jaeger.
