Motacilla dukhunensis, Sykes.
591bis. :- Butler, Guzerat; Stray Feathers, Vol. III, p. 489 ; Deccan, Stray Feathers, Vol. IX, p. 410.
SYKES' GREY AND BLACK WAGTAIL.
Length, 7.5 to 8; wing, 3.6 to 3.7; tail, 4.5 to 4.75 ; bill at front, 0.75.
Bill black ; irides brown ; legs black.
Mr. Hume points out, Stray Feathers, Vol. I, p. 30, that" the only ready and unfailing diagnosis of the two species," i.e, personata and dukhunensis, " is that, in both sexes, and at all seasons, the ear-coverts and whole aural region are in personata black, blackish or dark-grey; in dukhunensis, pure white or greyish or sordid-white." This marked difference, coupled with the conspicuously greater amount of white on the wings of personata, as compared with those of dukhunensis, ought to render the separation of any specimens of the two species comparatively easy.
This Wagtail is common during the cold season in both the Deccan and Guzerat. It also occurs at Neemuch in Rajputana.
