About Pica bottanensis Delessert, 1840
The black-rumped magpie (Pica bottanensis Delessert, 1840) has a black-and-white plumage, distinguished from the closely related Oriental and Eurasian magpies by its namesake black rump, brighter plumage, stouter bill, and shorter tail. The species' wings and tail are black, iridescent, and faintly glossy, with a faint greenish-blue tint; its flanks and central underparts are white. Wing length for females measures 233โ250 mm (9.2โ9.8 in), while male wing length is 241โ259 mm (9.5โ10.2 in), and tail length measures 250 mm (9.8 in).
Black-rumped magpies range from central Bhutan to Qinghai, western Sichuan in west-central China, and eastern Tibet. They occupy farmland and other semi-open habitats including farming districts, parks, and gardens. They are uncommon at high altitudes, though individuals have been observed as high as 4,800 m (15,700 ft), with nests recorded at 4,400 m (14,400 ft).
