观察细节
Foraging on wall and in bushes and small trees, did not observe any particular motion of wings or tail but I was not looking for those things. Pale warbler with grayish upperparts, white underparts, pale supercilium that extended beyond eye, dark legs, square-tipped tail, and entirely pale lower mandible. Was not sure what it was, as square-tipped tail and entirely pale lower mandible seemed to rule out Blyth’s Reed, Booted, and Syke’s Warblers. However, received feedback from another individual who identified it as a Booted because of the following: “It has a more Phylloscopine appearance with the small bill, rounded head, moderate pp and tail versus Sykes's which has an altogether more Acrocephaline look, particularly about the head and bill. Plumagewise, note the supercilium is rather broad above and beyond the eye where it ends squarely and abrubtly. This individual has a rather poorly defined eyestripe, as are the darker centres to the tertials, likely due to bleaching. Bill pattern is variable in Booted so the absence of a dark tip, though not typical, is within range.”
