Parasitic Jaeger: Seasonal Occurrence & Geographic Distribution

Parasitic Jaeger Stercorarius parasiticus

Lower Coast Status: Rare migrant and winter visitor along the coast; very rare in summer.

Texas Pelagic Status1: Very rare in summer, common in late fall and probably winter.

TX Status2: Uncommon migrant and rare winter resident in offshore waters and 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.
