486 BARE BRITISH BIRDS 



reddish chesnut ; remainder of the under surface yellowish white ; tail chesnut for the basal 

 half, black for the terminal half. The adult female is paler, with the under parts buffy white, 

 with a blackish brown band across the chest. Some old females attain blue feathers on the 

 throat, [w. p. p. and T. w.] 



2. Distribution. This race of bluethroat breeds in Sweden, Lapland, North Russia, and 

 the tundra of West Siberia east to lat. 66 N. on the river Yenisei. It winters in North-east 

 Africa and occasionally in Western India, visiting Eastern Europe and Transcaspia on migration. 

 Has occurred once on the Isle of May, in September 1909. [F. c. R. j.] 



WHITESPOTTED-BLUETHROAT [Cyanecula svecica cyanecula (Wolf); Cyanecula wolfi 

 Brehm. French, fauvette gorge-bleue ; German, weiss-sterniges Blaukehlchen ; Italian, 

 pett'azzuro a macchia bianco], 



1. Description. Differs from the redspotted-bluethroat only in having the chesnut patch 

 on the throat replaced by one of silvery white, [w. p. p. and T. w.] 



2. Distribution. The breeding-grounds of this race are situated in Middle Europe, includ- 

 ing France, the Low Countries, Germany, the Russian Baltic Provinces to St. Petersburg, Poland, 

 and West Russia, Austro-Hungary, locally in Switzerland, and apparently in small numbers in 

 North Italy. In South Russia and Central Asia it is replaced by allied forms. The main 

 stream of migration passes through Western Europe (S. France, Italy, and the Iberian Peninsula) 

 to North-west Africa, but some birds also migrate to North-east Africa. Seven males have been 

 recorded from Great Britain (three Sussex, one Kent, one Yorks, and two from Fair Island).

NORTHERN-NIGHTINGALE [Luscinia lusdnia (Linnaeus). Thrush-nightingale. French, 

 rossignol progne ; German, Sprosser ; Italian, rusignolo inagyiore]. 



1. Description. Differs chiefly from the common-nightingale in having a short first 

 primary which does not reach to the end of the wing-coverts, whereas in the common- 

 nightingale it reaches a quarter of an inch [6 mm.]. The sexes are alike in size and 

 coloration. Length 6J in. [165 mm.]. It is, however, larger than the common species, 

 less rufous in colour, and has the sides of the throat and chest indistinctly and obscurely 

 spotted, [w. p. p. and T. w.] 



2. Distribution. Breeds from the southern half of Sweden, Southern Finland and Denmark 

 to the Baltic coasts of Germany and the eastern provinces of that country, Russia east to the 

 Urals and south to the Crimea and Caucasus, Galizia and Transylvania, also locally in Roumania. 

 In Asia its breeding range extends east to the Altai. Its winter quarters lie in East Africa, and it 

 has been recorded south to German East Africa and the Zambesi. Casual in Western Europe, and 

 has been recorded twice (or possibly three times) from Great Britain (Fair Island, 1911 ; Kent, 

 1904; and possibly Norfolk, 1845). [F. c. R. J.] 



THE WARBLERS 1 



[ORDER: Passeriformes. FAMILY: Turdidce. SUBFAMILY: Sylviince] 



[SiBERiAN-RuBYTHROAT [Luscinia calliope (Pallas)]. Is said to have been observed in 

 October 1900 in Kent, but the evidence is inconclusive. It breeds in Siberia and North-eastern 

 Asia, wintering in India, China, and the Philippines, and has occurred casually in S. France and 

 Italy as well as in Russia. [F. c. R. J.] ]
