17.2 X 12.2 mm. (dwarfs). As will be seen the variations in size and 

 shape are very great, but on the average the eggs are slightly larger than 

 those of the Blue headed form. Average weight (13 eggs) 110 mg. Six 

 full eggs weigh 2.111 g. (Foster).

Breeding Range: Europe generally, excepting the British Isles, 



N. Scandinavia and Russia, the Iberian, Italian and Balkan peninsulas and 



S. Russia, where it is replaced by other forms. 



British A few iustauces of the breeding of this race in Great Britain are 



on record, usually near the coast. Hancock mentions four nests in the 



Tyne valley, near Gateshead in 1869 — 70 {Cat. Birds NortJmmherland and 



Durham, p. 60); it has also been recently recorded as breeding in Sussex, 



near Winchelsea, in 1901 and 1903 {Zool. 1901, p. 389'; 1903, p. 420), and 



subsequently in other localities (N. F. Ticehurst). It may possibly have 



also bred in Suffolk and Kent.*
