Vernacular names. The same as for the last bird.
Description. Similar to C. s. suecica but with the throat paler and the red spot large and rusty-red; the upper parts are a trifle paler than in the typical form.
Colours of soft parts and Measurements as in the last bird.
Females taken by Osmaston breeding in Ladakh show a great deal of blue on the throat.
Distribution. According to Hartert this form breeds in West Turkestan to East Trans-Caspia and to the Southern Urals, wandering as far as North-West India etc. in Winter. The birds from the Altai and Eastern Turkestan he separates as discessa (Mad.), said to be a slightly smaller and still paler form. From the material available in the British Museum I cannot distinguish between these forms and birds killed in India in Winter range from the smallest and palest to specimens equal to the darkest Western European specimens.
In India this Blue-throat is found practically all over India and Ceylon.
Nidification. Ludlow (Journ. B. N. H. S. xxvii, p. 143) writes that he obtained a nest with four eggs of this Blue-throat at Mulbek in Ladak with four eggs measuring 19.75-20.25 x 14.75-15.0 mm. At Bhet Kharta, a day's march distant, he found two nests of the Eastern White-spotted Blue-throat. More recently Osmaston has found both species breeding together in the same country.
Habits. Those of the preceding race.
