Is nearly related to B. ferox and bears much the same relation to that species as B. vulgaris does to B. desertorum.
In habits also it resembles that species, and is generally to be met with in the open country. It breeds commonly in south┬Čeastern Siberia, in Dauria on the steppes near the Onon river, and in the vicinity of Argoun, the nest being placed on a rock. The eggs 2 to 4 in number are usually deposited in May and vary, from white very sparingly marked, to bluish white or white with a faint reddish tinge richly spotted and blotched with reddish brown, and in size average 2.44 by 1.92.
