Suimanga de Penacho Rojo

Identificación

The scarlet-tufted sunbird is a large sunbird. Adult males have long tails, up to about 20 centimetres (7.9 in) in length, and scarlet pectoral tufts up to about 10 millimetres (0.39 in) wide. These tufts can be seen in flight and when the wings are rearranged, but not in perched birds. The head is black and the upper parts are metallic green, appearing almost black from a distance. The rump is bluish and the wings and tail black, the latter having elongated central feathers. The underparts are iridescent green, fading to bluish-violet on the upper belly and black on the lower belly. The female has brownish-grey upper parts, brownish-black wings and a dark brown tail. The underparts are whitish with dark mottling. The pectoral tufts are smaller than those of the male and may be rather more orangey-red. The juvenile is similar to the adult female but lacks the pectoral tufts.

Distribución y hábitat

The scarlet-tufted sunbird is found at very high altitudes in the Afroalpine Rwenzori-Virunga montane moorlands and East African montane moorlands, though also found at lower altitudes. Its normal range is on several disjunct areas of montane forest and moorland between 3,000 and 4,500 m (9,843 and 14,764 ft) in altitude, which encompasses a number of zones of vegetation. It is especially associated with giant lobelia, feeding on the nectar and insects on the plants, and using the tall flowerheads as song-posts. At lower altitudes it feeds on Protea and other plants.
