Jaeger, Pomarine (Local Rarety)
-Stercorarius pomarinus (Temminck)
The most robust of the jaegers with decidedly heavier and longer bill and usually longer wing. Adults are distinguishable by the tips of the elongated central tail feathers, which are blunt and are usually twisted so that they are nearly or quite vertical. There are two colour phases. Adults (light phase): top of head black. Wings and tail sooty greyish-brown. Primaries whitish at bases with whitish shafts. Throat, neck and breast white, the sides of the neck suffused with golden yellow and usually there is a more or less complete band of dusky mixed with white across the breast and more or less dusky marking on sides. Posterior abdomen and tail coverts greyish brown. Adults in dark phase are uniform greyish-brown above and below, but with whitish areas on wings in light phase.
