227. Acredula caucasica

227. SUBSP. ACREDULA CAUCASICA.
Acredula caucasica (Lorenz.) Beitr. Orn. Nords. Kauk. p. 60 Nachtrag. (1887) ; Dresser, ix. p. 113, pl. 655, fig. 2.
Ad. (Kuban). Crown white, forehead marked with reddish brown, supercilium reddish brown above, blackish brown below ; back pale slaty grey, darker on the upper part ; upper tail-coverts grey faintly tinged with rose ; wings blackish, secondaries margined with white ; tail black, all but the central feathers margined and tipped with white, the outermost almost entirely white ; under parts white faintly marked with grey on the sides of the breast ; bill and feet blackish ; iris brown. Culmen 0.3, wing 2.5, tail 3.35. tarsus 0.64 inch.
Hab. The Caucasus where it is resident and not uncommon.
In habits it assimilates closely with its allies, and though its nest and eggs are unknown, they will doubtless be found to resemble those of A. caudata. Acredula dorsalis Madarasz, of which I examined the type in Buda-Pest, is not separable from the present sub-species, but Acredula senex Madarasz, from the north Caucasus differs in having the head white and the back paler and greyer. Culmen 0.25, wing 2.35, tail 3.1, tarsus 0.55 inch.
