Gurney's Sugarbird

Gurney's sugarbird (Promerops gurneyi) is a medium-sized passerine endemic to the mid- and high-altitude grassland velds in southern Africa. It belongs to the family Promeropidae, which contains one genus, Promerops, and two species. Gurney's sugarbird feeds on nectar from Protea bushes as well as on small insects. This bird is characterized by its long, graduated tail and decurved beak. Gurney's sugarbird has a long, decurved bill characteristic of nectarivores. It has a chestnut-coloured forehead, along with a faint white eyestripe and white mustachial stripe. A white throat stands out against the russet breast. This species of sugarbird has a dark grey back, and a conspicuous bright yellow rump makes this bird easy to spot. The tail is long and graduated, ranging from 11 to 19.3 cm in length. Females are smaller than males, with shorter bills and tail feathers. Males also have triangular-shaped bulge on the sixth primary feather, used in mating displays. Immature individuals are duller than adults and have a greenish tinge to both their breast and yellow rump. Further, their secondary feathers are edged with a brownish colour.
