No. 49. Archibuteo Hemiptilopus, BLYTH.
THE BROWN EAGLE BUZZARD.
Nothing appears to be known in regard to the nidification of this species, of which only three or four specimens are, I believe, in existence.
Dr. Jerdon's description and dimensions are taken from Mr. Blyth's notice, in the J. A. S. Mr. Blyth had only seen a single specimen, so that, as in most species of Buzzards, we may expect to meet with other examples, in very different stages of Plumage. The dimensions given, are those of this single specimen, " probably," says Mr. Blyth, " a fine female," and the males will consequently, if this was a female, prove considerably smaller.
In regard to the breeding of the nearly allied European species, A. Lagopus, the only notice I have met with, is the following, in Yarrell's British Birds. " According to M. Temminck, this bird generally builds on high trees, and lays three or four eggs. A coloured figure of the egg will be found in the first part of Dr. Thieneman's work on the Eggs of the Birds of Europe, tab. III, fig. 2 : this representation is two inches two lines in Length, by one inch eight lines in breadth, of a pale brownish white, blotched over the larger end with darker brown."
Of the nearly allied A. Ferrugineus, Captain Blackiston records finding nests in April and July, between the north and south branches of the Saskatchewan river in the interior of British North America. One nest, he says, which contained four eggs, placed in an Aspen tree, some twenty feet from the ground, was composed of sticks, lined with Buffaloe wool, and measured 2 1/2 feet across ; another nest contained five eggs, and was situated in a tree, only ten feet above a lake, a third nest contained two eggs." The eggs, he says, are of a white colour, plain, or more or less blotched with reddish brown.
Mr. Blyth considers our Indian species to be a mere straggler from the Mongolian Region, but it does not seem to have been procured either in Northern China, or in any part of Siberia, or the Amoor land, by Radde, Middendorf, Pallas, &c.
* In the Ibis, for 1868, he gives the " iris bright clear yellow with a black outer circle.
