Red-and-blue Lory

Identificazione

The red-and-blue lory is roughly 12 inches (30 cm) in length, including the tail. The species is sexually monomorphic, i.e. sexes are visually alike.<p>The beak is short, sharply curved, and bright orange. The feathers nearest the cere (the area nearest the nostrils) are bright red. The crown of the head is intense purple. The back of the head is red, and the nape of the neck is intense violet. An indigo-violet stripe runs diagonally from the cere corner to the nape of the neck. The bird's plumage is mostly bright red. The rump and lower belly are a slightly deeper red. The breast has a broad band of deep blue. Extending the color from the nape, the bird's back is a deep violet purple. Wing and tail flight feathers - rectrices and remiges - are between red and red-violet. The wing covert feathers are black and red with black tips. The leg feathers are bluish-purple. The feet are medium gray, and the claws are black. The cere is very dark gray, and the irises of the eyes are dark brown.<p>The red-and-blue lory's voice consists of short, harsh chattering screeches. Their flight is said to be quick and straight.

Tassonomia

There are two subspecies recognized, of which one is extinct:<p>E. h. histrio is thought to have become extinct due to deforestation. The subspecies E. h. challengeri, formerly thought to have existed on Miangas or Nenusa, was also previously thought to have been driven to extinction, with the populations on the Talaud Islands belonging to the subspecies E. h. talautensis. However, the purported range of challengeri has never been established and is thus thought to be erroneous, so it was synonymized with E. h. talautensis by the International Ornithological Congress in 2022, thus "reviving" challengeri as an extant subspecies.

Areale e habitat

The red-and-blue lory is now confined to the Talaud Islands off northern Sulawesi, Indonesia, where almost all individuals appear to inhabit a single island (Karakelang). Further populations, some apparently introduced, disappeared during the 20th century from Sangihe, Siau and Tagulandang. The population is thought to be in rapid decline.<p>The birds inhabit forests from sea level to about 1,500 meters above sea level. The population is only sustainable or viable on Karakelang, and their population on that island is fragmented into approximately four locations. This restricted range makes them very vulnerable to potential extinction.
