The uppertail is same but without streaks. The flight feathers are brownish with off-white tips of the outer webs of primaries. The tail feathers excepting central are dark-brownish with white terminal spots; central tail feathers are narrow grey-brownish ended. The throat is off-white. There are two black broad patches on the craw-sides. The breast, belly and flanks are whitish-grey. The breast is with dark mottles. It is very resembles the Calandra Lark and is distinguished by the lack of the white terminal band on the wing and white outer tail feathers. The black patches on the craw-sides are usually less than on Calandra Lark; the breast often without mottles. Then the underwings are dark but not as black as on Calandra Lark.

The Bimaculated Lark breeds and occurs on migration in the southern half of Kazakhstan, in north to the upper valley of Emba, Dzhezkazgan, Norther Trans-Balkhash area, Ayaguz river valley, southern part of Zaysan depression (where one juvenile recorded on 28 July 2001). Summer records on 18 June 1975 are known from Kurgaldzhino.
The Bimaculated Lark is common, in places numerous or rare, breeding migrant. Inhabits crushed clay stone deserts with poor vegetation, stony slopes with low grass, wormwood/grass and wormwood/fescue steppes on plains and in foothills up to 1700-2000m. During migration shows a preference for stubble fields and tracks. Appears from end of February to early March, most migrating in March in flocks of several dozens. Migration finishes late March to early April. Breeds in separate pairs, not far apart. Nest is built on the ground in a shallow scrape under a grass shelter and is made from dry grass and rootlets. Clutches of 3-6, more often of 4-5 eggs, is laid from mid April to late June. Both parents feed juveniles, which fledge late May to early July. Repeated breeding after nest loss probably occurs. Autumn migration begins in late August, most birds departing between the second half of September and mid October; the last flocks generally recorded late October to early November.
