those observed in England: here it usually avoids the dwellmg of man; there it would appear to be eee necessary to point out the differences which exist in this bird and the Common Sparrow. In the first place, it is a smaller bird, neater in contour and broader in its markings ; in the next, the sexes are alike in colour ; and thirdly, there is scarcely any difference between the plumage of ‘oe and winter, the bird being as nearly alike at both seasons as may be, except in the colour of the bill, which during the breeding-time is of a nearly uniform black, while in winter it is yellow a the base. In ue gregarious and other habits it very closely resembles the Common Sparrow: but on this part of the bird’s economy I had better perhaps quote Mr. Yarrell’s account :— ‘It is generally described as frequenting trees, and building in the holes of decayed pollards ; but that this is not its universal habit I learn from the Rev. James F. Dimock and his brother, George Dimock of Uppingham, in Rutlandshire, who informs me that ‘This bird frequently builds in the thatch of a barn, in company with the House-Sparrow, not, however, entering the thatch from the inside of the building like them, but by holes in the outside. Five or six instances of this sort occurred in one building; and one or two pairs built about the farm-house. To be certain as to the species, some old birds were watched, shot when quitting their holes, and the eggs taken. They also built in the deserted nests of Magpies and Crows, in which they formed domed nests, like the Common Sparrow when it builds among the branches of trees; and one pair built in a hole that had been occupied by a Green Woodpecker. These different modes of building occurred in a country abounding with pollards, ash- and willow-trees. Mr. Hoy informs me that he has observed on the Continent that this species often builds in holes of the tiling of houses and in stacks of wood-faggots ; and Vieillot says that in France they occasion- ally build in old walls not many feet above the ground. The nest is formed of hay, and lined with feathers. The eggs are four or five in number, of a dull white, speckled all over with ash-brown; the length 83 lines by 6 lines in breadth.’ Mr. Hewitson states
