Long-tailed Jaeger: Seasonal Occurrence & Geographic Distribution

*Long-tailed Jaeger Stercorarius longicaudus

Lower Coast Status: Accidental along the coast in summer and fall. There are three records from the Valley: two from Port Isabel on 8 June 1989 and 17 June 1992, and one off South Padre Island on 26 September 2004.

Similar Species: Long-tailed Jaeger is the smallest (and rarest) of the three jaeger species. Adults are fairly distinctive, lacking white wing patches on underwing and long central tail feathers. However, juveniles can be similar to larger Parasitic Jaeger. Juvenile Long-tailed Jaeger is usually gray-toned (Parasitic is browner), with strongly barred tail coverts and a pale head. Sometimes visible are contrasting white shafts of the two outermost primary feathers of the upperwing.
