Observation details

11.16 Bird1 - Long-tailed Jaeger - All dark underwing coverts indicate an adult and the pale tarsus in adult is a diagnostic feature for Long-tailed. Pale tarus is visible in images like 'Bird1-ESp Skua 11.19.1.jpg', 'Bird1-_SAM7395_00065.jpg' etc. - Relatively small (compare with other 2 Parasitic Jaegers which were harassing it) - In those chasing images, also note relatively more slender wings. Check especially 'Bird1-Pale-Bodied-Bird-ESP Skua's 11.17.2.jpg' (Remember that angle can affect this, like in the topmost bird in the same image) - Greyer tones to upperparts, contrast it against the browner Parasitics - Stubby, dark beak (difficult to appreciate from the avaialable images) - Tail shape is typical of winter Long-tailed, visible in 'Bird1-ESP Skua's 11.19.2.jpg'
