Initially observed a juvenile jaeger flying southbound between the Deltaport and ferry jetty and attempted to pursue it by boat but were outpaced. Later relocated it on the south side of the ferry jetty near the breakwater where it circled a flock of gulls sitting on the water before continuing to the SSW. Identification made from examining our photographs which showed characteristics indicating Long-tailed Jaeger: - Only 2 white primary shafts; - The white primary flash on the underside is very small and appears indented/notched near p9; - There are no apparent buff tips on the dorsal side of primaries (like PAJA); - Undertail and uppertail coverts boldly and neatly barred (not wavy and irregular like PAJA); - Secondaries blacker and contrasting with rest of upperwing; - Overall cold greyish tone. - The blunt tips to the longish central rectrices are diagnostic for juv LTJA
