| The identity of this bird is not certain since it does not fully match any known taxon. Juvenile bush warblers are relatively little known.
Peter Kennerley comments as follows:
At a guess, I'd say it is a juvenile from the Spotted Bush Warbler complex.
It shows emarginations on p3-5, which is characteristic of the Himalayan
forms in this group. The emargination on p5 eliminates the Siberian
breeding, but otherwise similar, Baikal Bush Warbler in which the
emarginations are restricted to p3-4. All Himalayan Cettia would show an emargination on p6 and some also on p7.
The date, yellowish wash to the throat and centre of the belly are typical of a juvenile, as are the slight gape flange the overall 'fluffy' appearance of the body plumage, and the fresh, unworn primaries and rectrices.
The short tail and faint pale tips to the undertail coverts point to
something from the Spotted Bush Warbler complex, and the location points to the taxon kashmirensis, which Alström et al. (2008) suggest is specifically
distinct from Bradypterus thoracicus.
Having said this I haven't seen any of the Himalayan forms in juvenile
plumage so I could be completely wrong here. |
