Mie Js ie Gurney assures me that it is an example of the species to which the above names have been
assigned by the various authors mentioned, that of desertorum having the precedence. The countries

frequented by it are Algeria, Mogador, European Turkey, the mouths of the Volga, Syria, India, and Ceylon.

Mr. Gurney considers that there is no specific difference between this bird and that which is named in
collections Buteo cirtensis. He came to this conclusion after examining specimens from Mogador, Tangiers,
Erzeroum, and the mouths of the Volga. It is included by Schlegel in his «Fauna Japonica ;’ so that it has

a very wide range.

‘The appearance of this bird when alive,” says Mr. Gurney, ‘is less heavy and more elegant than that of
B. vulgaris. My living specimen, which was dull-brown when I bought it, has moulted into a rich rufous
plumage; and one that was alive in the Zoological Gardens a few years since, underwent a similar change.”
According to M. Favier, it nests among the rocks, and the male takes its turn in sitting. The egg has a
strong resemblance to that of the Black Kite, but is a little more pointed, and the ground-colour a cream-

white, that of the former having a greenish tinge.

Mr. Gurney states that ‘the cere, tarsi, and feet of this Buzzard are lemon-yellow ; the irides are
sometimes light-hazel, and at others yellow, probably assuming the latter colour as the bird advances in
age ; a similar variation, however, which exists in the irides of the Common Buzzard is not always referable

to age, as I have ascertained by experience.”
9. Bureo LINEATUS.

Red-shouldered Buzzard.

It becomes necessary to notice this species, a single example having been shot at Kingussie, in
Aberdeenshire, on the 26th of February, 1863. It is now in the collection of Mr. Newcombe, of Feltwell
Hall, Brandon, Norfolk. As this is a strictly North-American species, I do not consider it necessary to
figure it; but such of my readers as may desire to know its history can refer to the writings of Wilson,

Audubon, and other authors on American birds.
