having the sexes different in colour, both male and female 

 having the tail for the most part chestnut. 



Two species of Blue-throat are recognised, one with a red 

 spot (C. suecica] and one with a white spot (C. cyaneculd]. 

 The latter is not nearly so wide-spread as the former bird, and 

 only occurs in Central Europe, scarcely reaching as far east 

 as Russia, but visiting Northern Africa and Palestine in winter, 

 recurring in Gilgit, and wintering sparingly in India.
