- White eyestripe

- Red patches on tail sides (all ages)

Distribution
Main breeding range is in the north and east of the Region, breeds through most of Norway, upland Sweden and north Finland and from Poland and the Baltic States east to the Urals, breeding south to northern Ukraine. Also breeds in very scattered pockets across Europe in Spain and west and central France east to Hungary with an isolated population in the Caucasus and north-east Turkey. Has bred in Britain, Switzerland, Italy and Romania.
A migrant over most of range leaving in August-September to winter around the Mediterranean in small numbers, more commonly in sub-Saharan Africa and the Middle East and returning in March-May. Passage birds occur throughout Europe including Britain where 50-150 occur in most years, mainly on the east coast and Shetland in particular with May and September the peak months.
Vagrants recorded Iceland and Faroes, Ireland and Greece.
Taxonomy
Subspecies
A number of races occur in the Western Palearctic some of which are separable in the field, differing in throat colour of breeding male. The nominate svecica has a blue throat with red central spot and broad black band beneath. Central European cyanecula has white throat spot (or, rarely, none at all), and darker upperparts and namnetum is similar but smaller. South Russian pallidigularis has pale chestnut bar or triangle on paler blue throat and narrower black band and Caucasian magna is similar but larger.
However, there is much individual variation and intergradation between races and isolated pockets of red-spotted birds within range of cyanecula.
There are 12 subspecies[1]
- L. s. svecica: Scandinavia across Siberia to western Alaska; winters North Africa, southern Asia
- L. s. namnetum: Western France
- L. s. cyanecula: Central Europe and Spain; winters to North Africa
- L. s. azuricollis: Northern Spain
- L. s. volgae: North-eastern Ukraine to middle Volga River
- L. s. magna: Caucasus area, eastern Turkey and Iran; winters to Sudan and Ethiopia
- L. s. luristanica: Armenia to south-western Iran; winters to Iraq and the Sudan
- L. s. pallidogularis: South-western Siberia to Turkmenistan, Altai Mountains and upper Yenisey
- L. s. tianschanica: Pamir Mountains and Tien Shan Mountains
- L. s.a abbotti: Western Pakistan and north-western India
- L. s. przewalskii: Inner Mongolia to western China (Qinghai) and southern Tibet
- L. s. kobdensis: Western China (Xinjiang)
