Amber Mountain rock thrush

The Amber Mountain rock thrush (Monticola sharpei erythronotus) is a songbird in the family Muscicapidae, formerly placed in the Turdidae together with the other chats. It is now usually considered a subspecies of the forest rock thrush.

Distribution

The Amber Mountain rock thrush is endemic to Madagascar where it occurs only on the Amber Mountain massif in the north of the island.[1]

Description

This is a small forest-dwelling thrush, growing to a length of about 16 cm (6.3 in).[2] Males have blue hoods, chestnut upperparts, bright orange tail with brown central feathers and orange underparts. Females are mostly brown with an orange wash on the underparts and lack the blue hood. Males are distinguished from other rock-thrushes by the dark rufous back, while the females have bright orange tails and lack white streaking on the breast.[3]

Habitat and ecology

It inhabits mid-altitude and montane humid, evergreen forest from 800 to 1,300 m (2,600 to 4,300 ft), and forages inconspicuously in the understorey and on the ground, sometimes sallying to take aerial prey. The species nests in tree hollows or in crevices under overhangs.[1][2]

Conservation status

The Amber Mountain rock thrush is listed by the International Union for Conservation of Nature and Natural Resources as Endangered because it has a very small range and its forest habitat is declining in both area and quality. The population is small and believed to be declining, albeit slowly. The total population of this species is estimated to number less than 5,000 individuals, which occur in a single block of forest in the Amber Mountain National Park. It may be declining, although so far there has been relatively low levels of habitat loss in the area of its occurrence.[1]

Taxonomic notes

The Amber Mountain rock thrush has been regarded as a separate species but this view is in doubt. It had been split from the forest rock thrush because of a variety of morphological differences and in spite of an absence of genetic distinctiveness. As the forest rock thrush and Benson's rock thrush have been lumped into Monticola sharpei this taxon has followed suit.[1]

gollark: Actually, I think billing the v-script creator would work fine.
gollark: You could say "v-scripts"/"t-scripts" or something, if you MUST shorten it.
gollark: Or, well, they can except they lose a minimum of 1KST there *or* I have to add tons of irritating code for fractional billing and interfacing with everything with that and it probably breaks in horrible ways.
gollark: SC and krist itself don't have companies, meaningfully.
gollark: If you had, I don't know, a service which takes krist and sends it back to you a day later for whatever unfathomable purpose, then if someone wants to just feed that 5KST, they can't due to the fee.
