Bluethroat

The bluethroat is part of the Old World flycatcher family. It breeds in wet birch wood or bushy swamp in Europe and across the Palearctic (across Europe and Asia north of the foothills of the Himalayas and North Africa) and western Alaska. It winters in the Iberian Peninsula, the northern half of Africa and southern Asia, including the Indian subcontinent. It is often called a chat. I saw this female bluethroat in Keoladeo NP in India.

It is plain brown above, except for the tail that has black outer corners and red basal side patches. It has a white supercilium and males have a throat pattern with a glossy blue throat bordered with a narrow black band and a broad red band below that. There is often a central spot, either red or white, in the middle of the blue throat. There are either seven (Shirihai) or eleven (IOC) subspecies that differ in the extent and intensity of the blue on the throat in the males and whether the blue has a central spot, or not, and if it does, the color of the spot. The nominate subspecies Luscinia svecica svecica, the one I saw in Keoladeo NP in India, is known as the red-spotted bluethroat and breeds in the subarctic shrub tundra from Scandinavia east to western Alaska and winters in southern Asia in India, Pakistan and the Middle East. The throat is blue with a red spot.
