NESTING-SERIES_OF BRITISH BIRDS. 141 
nest in the mountain-ranges of Central Europe. In England it breeds 
principally in the northern counties, and in Scotland it is a resident 
throughout the year wherever woods and thickets of brushwood are 
found. 
The nest, which is a beautiful little structure, is usually placed in a 
sheltered position in a low tree or bush and contains from four to six 
eggs. In the south of England the breeding-season commences in 
April, but in the north it is often a month later. Two broods are 
frequently reared in the season.

No. 13. TWITE. (Linota flavirostris. ) 
The Mountain-Linnet, as this species is often called, is a resident in 
the British Islands, breeding on the wild moorlands from the Midlands 
northward, and is especially numerous on the islands off the coast of 
Scotland. It is also common on the mountains of Ireland. During 
the winter months it leaves the higher ground and is then to be met 
with in flocks near the sea-coast, except in the south-west of England 
and Wales. The nest made of dry twigs and roots, lined with wool, 
hair, and feathers, is usually placed among heather or in a low bush, 
and often on the ground among grass or other herbage. From four to 
six eggs, of a pale greenish-blue blotched with reddish-brown, are laid 
towards the end of May.

No. 14. HOUSE-SPARROW. (Passer domesticus.) 
There are few localities in the British Isles in which the Sparrow 
has not attached itself to the habitation of man, appearing and rapidly 
increasing wherever the land is brought under cultivation. Though a 
harmless and pleasant companion to dwellers in towns, it becomes, 
owing to its numbers, a serious pest in the country, where it does an 
infinite amount of mischief at all seasons. It is not particular as to a 
site for its nest, which is placed in almost any suitable situation on 
buildings or in trees in their vicinity. When building in trees and 
adopting its natural mode of nidification, it constructs a large domed 
nest of any dry stuff, well lined with feathers, and with an entrance in 
the side. It frequently takes possession of the nest of both the House-
