summer may have brought forth. Its motions are all effected very quietly; and so closely does the colouring of the bird assimilate to that of the leaves of the trees, that it would be aller impossible to detect it, were it not for its movement and the utterance of its pretty but subdued song, velba is oe on the wing as well as from some high tree. ‘‘ It consists,” says Mr. Macgillivray, “of a repetition of the syllable : Reet ten or more times, the first notes being prolonged, the rest gradually fallmg and becoming shorter. It may be heard at a distance of as much as six hundred yards or more, and is continued till the middle or end of July; after which time it begms to wane in strength, though repeated during fine weather till the last. It begins with the highest note, and gradually goes lower, dwelling on each several times; in all, five whole notes of music. It is wont also, particularly in the early summer months, to emit a small and rather shrill cheep. When warbling its sweet and melodious lay, the throat is somewhat swollen, and the whole body thrills with the effort.” (Morris’s Hist. Brit. Birds, vol. i. p. 243.) The nidification of the Willow-Wren takes place soon after its arrival; the nest is placed on the ground, and so artificially concealed that it is often most difficult of detection. In some instances I have known a covered passage through the grass of a foot in length, before the nest was reached. A nest with eggs taken near the Holt at Preston Hall, near Maidstone in Kent, on the 29th of May, 1858, was secreted among thick herbage on the shelf of a bank; it was of a partially domed form, outwardly constructed of moss, leaves, and dried stalks of grasses, and warmly lined with at least two hundred pheasant-feathers. Another nest, taken at Formosa, near Cookham in Buckinghamshire, was of a deep cup-shaped form, roughly built of moss, dried leaves, and very fine straws, and thickly and warmly lined with soft downy feathers. It contained six eggs of a dull pinky white, plentifully sprinkled with coarse blotches of light red ; when blown, the ground-colour became opaque. During the sojourn of the bird in this country, from April to September, two broods are reared. The young, on leaving the nest, assume the colouring of the adult ; the whole of the feathers, however, are more suffused with yellow, particularly those of the under surface; at this age, therefore, the bird bears a richer livery than when adult. Before leaving this country, a perfect moult takes place in the old birds; and the sexes closely assimilate both in tint and size; after the moult, they are more yellow than when they arrive in spring, but are not so uniform or so fine in colour as the young. All the upper surface yellowish olive ; wings and tail brown, margined with yellowish olive; over the eye a stripe of yellow; mark before and behind the eye brown; under surface white, suffused with yellow on the sides of the neck, breast, flanks, and under tail-coverts ; upper mandible light olive-brown ; under mandible flesh-colour ; irides brownish black ; legs and feet light brown; the under part of the tarsi and the soles of the feet inclining to flesh-colour. The figures represent a male and female of the size of life, on a species of willow gathered on the banks of the Thames in the month of April. ¥ G AC XC iC G mF. I rae Sel NE Rt RAT A ORT ra ———
