adult, but also from each other. I bave seen an immature example of a uniform chocolate-brown, and c ’ c ‘ LCL . : ; a : : 3 others in a costume of mingled buff and brown. The bird evidently becomes whiter as it advances in age ; some have delicate grey heads, and flanks beautifully barred with dark brown, while older birds have strongly blotched mananes over the whole of the under surface. The fine pair from which my figures were faker: eRe kindly lent fa me for the purpose by John Rocke, Esq. They were trapped near that gentle- man’s seat, Clungunford Hall, Shropshire, early in June 1865. | Sir William Jardine stated in his address to the Members of the Berwickshire Naturalists’ Club, in September 1836, that “The district around Twizell, in Northumberland, phe to be very ata to this species ; for within a few years several specimens have been Prog e both - the adult and the nena ture plumage. One of them was observed to rise from the site of a wasps’ nest which it had been attempting to excavate, and to a certain extent had accomplished the operation. The size of the hole which had been made showed that a much greater power could be employed, and that the bird possessed organs much better fitted to remove the obstacles which generally conceal its prey than a superficial examination of the feet A few hours afterwards the task was found to be entirely completed, the and legs would seem to warrant. A steel trap, baited with the comb, secured the comb torn out and cleared of the immature young. aggressor in the course of the next day, when he returned to review the scene of his previous havoc ; and dissection proved that at this time mammalia or birds formed no part of its food.” Mr. Thompson states that the stomach of an example killed in Ireland contained a few of the larvee and some fragments of perfect coleopterous insects, several whitish-coloured hairy caterpillars, the pupa of a species of butterfly, and also of the six-spot Burnet moth. One examined by White of Selborne contained limbs of frogs and many grey shelless snails. In Mr. Stevenson’s ‘ Birds of Norfolk’ it is stated that the stomach of an example killed at Holkham, and of a female taken at Saxmundham, was well filled with young wasps ; in a third, killed near Lowestoft, were found the remains of Blackbirds’ eggs, and in the throat of a fourth several small fragments of the eggs of the Song-Thrusb. Mr. Yarrell was told that one kept in confinement killed and ate rats as well as birds of considerable size. It will therefore be seen that, although wasps and their larvee form part of its food, its diet is so much varied that it may almost be regarded as omnivorous. Buffon says that in winter, when fat, it is itself very good eating. In bis remarks upon two small birds in full plumage, shot at Northrepps, near Cromer, on the 25th of Aueust, 1857, Mr. Gurney says, ‘* About 9 o’clock this morning I was riding along a broad green drive which runs through a wood in this place, when a Honey-Buzzard rose from the grass and alighted on a tree at the edge of the wood. I shortly after sent my gamekeeper in pursuit of it, and he succeeded in shooting it near the spot where I saw it. Hearing afterwards that it had been seen flying in company with a second specimen, he returned to the drive and succeeded in shooting that also, very nearly at the same spot where he had procured the first specimen, being guided in his search by loud whistling cries which the bird was making, probably as a call-note to the one which had been previously shot. About two hours later my son, who was passing through the drive, saw a third specimen rise from the ground and alight on a tree, in a similar manner and nearly in the same place as the first. The gamekeeper was again sent in pursuit ; but when he succeeded in getting a view of this bird, it had risen so high in the air that it was out of shot, and continued flying at a great height, in an inland direction, till it disappeared. Both specimens that were procured were in full adult dress, and possessed the beautiful grey tinge on the head which always distin- guishes the adult examples of this bird. On dissection both of these specimens proved to be male birds. Their stomachs contained the remains of wasps and wasp-grubs.” The vest, which is of a very large size, is placed in the forks of trees, often of the beech ; it is shallow in form, and built of sticks, of considerable size, intermingled with twigs with their leaves on, and is lined with leaves and wool. The eggs, which are generally deposited in June, are of a bright orange-brown, largely blotched, sometimes in the middle, at others principally at the larger end, with two shades of rich chestnut- brown ; their average length is about two inches, by one inch and three-quarters in breadth. The principal figure in the accompanying Plate represents an adult male, of the natural size, with a nest of the Tree-Wasp; the reduced hgures in the distance, an adult female and two immature birds.
