BRITISH BIRDS' NESTS. 323 



occupies less space, and her back is tiuged with 

 olive. 



Situation and Localitij. — Similar in all respects 

 to those of the Pied Wagtail. 



Materials. — -The same as are employed by the 

 bird just named. 



Eggs. — Five to seven, of a wider colour variation 

 than those of the Pied Wagtail, according to Mr. 

 Dixon. The ground colour varies from pure white 

 to bluish-white, speckled all over with different 

 shades of grey and brown ; sometimes a few hair- 

 like lines occur at the larger end. The markings 

 vary, both in regard to size and distribution, and 

 there can hardly be any safe means of identification 

 apart from the difference in the parent birds. Size 

 about "8 by "6 in. 



Time. — April, May, and June. 



Remarls. — Migratory, but little is known as to 

 its comings and goings. Although a common bird 

 on the Continent, only a few well-authenticated 

 instances of its breeding in the British Isles are 

 on record, and those in the southern counties of 

 England. It is, however, thought that it may 

 often have been overlooked from the fact that its 

 general appearance and eggs are so similar to those 

 of the Pied Wagtail, to aU except the practical 

 and experienced ornithologist. Notes : call, cliiz-zit. 

 Local and other names : Gre}^ and White Wagtail. 

 Said to sit pretty closely. The male differs from 

 that of the Pied Wagtail in being grey on its 

 upper-parts below the nape instead of black, but 

 the females of the two species only differ in 

 that of the White Wagtail being "pearl-grey or 

 very light ash-grey tinged with olive," and that 

 of the Pied Wagtail being "lead-grey mottled 

 with darker feathers " on those parts.
