It is said to breed in the North of England, but although I have met with the bird in great flocks, both in Yorkshire and Westmorland, during the autumn, I never discovered its nest upon the Fells. I have found it breeding on several Highland mountains, but as already stated, most numerously in the Outer Hebrides. How abundant it actually is in the Western Isles may be gathered from the fact that I have found no fewer than seven nests in the course of a zig-zag walk of a mile or so from the house of one friend to that of another. As an indication of the wide variety of sites chosen by the Mountain Linnet--as the bird is sometimes called--for its little home, I will mention the places in which I discovered the above-named nests. Two were in holes in a dry stone wall, the one containing eggs, figured in our illustration, at the top of a stone wall and sheltered by a piece of overhanging turf, which had been placed there to increase the height of the fence; one in a tuft of heather growing close to a half-buried rock; one in a furze bush where a Common Linnet’s nest might have been expected; another in a stunted gooseberry bush; and the last in an ivy geranium growing inside a small greenhouse, to which the birds gained entrance through a broken pane in the roof. On more than one occasion I have found a nest, containing eggs or young ones, under an overhanging tuft of grass growing from a crevice of rock on the small piece of North Uist Coast shown in the tailpiece to this article. [Illustration: TWITE ON NEST IN HONEYSUCKLE TIED AGAINST A STORM-SWEPT HEBRIDEAN GARDEN WALL.] A Twite’s nest sometimes takes a long time to build. I remember one that occupied a whole fortnight from foundation laying to completion. It is made of fibrous roots, dead grasses, and moss, with an inner lining of feathers, fur, or hair. The eggs number five or six, of a light bluish-green or bluish-white ground colour, marked with reddish-brown and dark brown spots and streaks.

On its upper parts it is olive-green tinged with yellow, except in the case of its wings and tail, which are dusky. The chin, cheeks, throat, and breast are yellow, and under parts white. A line of bright yellow runs from the base of the bill over the eye. The bird may be distinguished from its relative, the Willow Wren, by its larger size, broader yellow band over the eye, greener upper parts, and whiter abdomen, also by its longer wings. Its nest is also a safe guide to correct identification, as will be shown presently. The female is similar to the male in her appearance. [Illustration: WOOD WREN’S NEST AND EGGS.]
