Isabelline Wheatear Oenanthe isabellina breeds from southeast Europe to China (Xinjiang, Qinghai, Gansu, and western Inner Mongolia to northern Shaanxi). Strongly migratory, wintering from west Africa to Thailand. HABITAT & BEHAVIOR Breeds in deserts and semi-deserts and on sparsely vegetated mountain steppes, to 3500 m (11,480 ft.). Runs on ground after prey; also pounces from perch. ID & COMPARISON Monotypic; sexes similar. Plainly colored; mainly sandy-brown above and buffish-white below. Resembles non-breeding and especially first-winter Northern Wheatear Oenanthe oenanthe, but slightly larger and has longer wings and legs and shorter tail, thus more upright stance. Supercilium whiter before eye, not behind, as in first-winter Northern. Ear coverts always yellowish-brown; never shows black bandit’s mask (male Northern) or even a hint of a mask (female Northern). Black loral line fainter in female, absent in first-winter. Shows more white on tail than Northern, and black tail band is broader and black vertical bar shorter, resulting in a more stunted inverted T. Black alula often creates marked contrast with sandy-brown wings and is a useful way to separate from first-winter Northern. BARE PARTS Bill, feet black. VOICE During male’s fluttering display flight utters distinctive song consisting of whistles, chack notes, and mimicry of other passerines. — Craig Brelsford
