[Illustration: ROCK PIPIT’S NEST AND EGGS.] Its nest is situated under old matted tufts of grass, overhanging pieces of rock, and in crevices, and is made of small pieces of dry seaweed, dead grass of various kinds, and a few horsehairs. Seaweed is not always present in the structure, and horsehair frequently absent when the bird is breeding on small islands where it is not procurable. The eggs number from four to five, and have a grey ground colour slightly tinged with green or reddish-brown, closely spotted with dull greyish- and reddish-brown. They are occasionally marked on the larger end with one or two dark brown lines, and are larger than those of the other two members of the family breeding in our islands. [Illustration: seascape sunrise/sunset] =THE GARDEN WARBLER.= [Illustration: cluster of flowers] This species is about six inches in length, and on its upper parts of a light brown colour tinged with olive. Its under parts are brownish-white, darkest on the throat, chest, and sides. The absence of black or rusty brown on the top of the head always readily distinguishes it from the male or female Blackcap, and the colour of its throat and breast from either of the Whitethroats breeding in this country. The Garden Warbler arrives in Britain about the end of April or commencement of May, and takes its departure for Africa in September and October. It breeds sparingly in nearly all suitable parts of England except Cornwall, in Wales, in the South of Scotland, and occasionally in Ireland. It generally builds its nest at some little height from the ground in thorn, briar, bramble, gooseberry, and other bushes growing in woods, clumps of trees in the proximity of streams, orchards, shrubberies, gardens, and hedgerows. Sometimes the structure, which is made of straws, blades of dead grass, and rootlets, lined with horsehair, is hung amongst nettles like that of a Whitethroat, or placed low down in long grass, mixed with taller wild plants. The eggs, numbering four or five, rarely six, vary in ground colour from white to greenish-white or yellowish-stone-grey, are spotted, blotched, and clouded with underlying markings of ash-grey and buffish-brown. Some specimens are marbled with brown, and it is often a difficult matter to distinguish others from those laid by the Blackcap. [Illustration: GARDEN WARBLER ON NEST.]
