觀察細節

Gulls to the south started streaming north and we picked up an adult jaeger following behind. Dark capped with all black wings(top and bottom) and unmarked, pale yellow throat and belly. Observed harassing RBGU which it was slightly smaller or comparable in size. Later observed getting chased by an AHGU over wavetower, where the AHGU appeared much larger. Nice photos by Jude Szabo, Grant Stone and Mourad Jabra showing these features and lacking central tail feathers, explaining the missing tail streamers. Personal photo added.
