Moorland Chat
Pinarochroa sordida
A small, drab, dumpy, long-legged, short-tailed chat of high-elevation habitats. The tail has a black-and-white “T” pattern that is conspicuous in flight. Found mostly at high elevations in montane grassland, in moorland, and on rocky slopes. Perches conspicuously on low perches and forages by hopping across the ground. Tail pattern is similar to a wheatear’s, but Moorland Chat is smaller and shorter-tailed. Somewhat similar to other drab brownish chats, but found in different habitats, and also distinguished by the tail pattern. Gives quiet chirps, ticks, and scratchy calls.

The moorland chat was formally described in 1837 by the German naturalist Eduard Rüppell from a specimen collected in the Simien Mountains of northern Ethiopia. Rüppell coined the binomial name Saxicola sordica.<p>The chat was discovered on Mount Elgon on the Uganda-Kenya border by Frederick Jackson. The English geographer Halford Mackinder brought back the same bird from Mount Kenya in 1899. He presented a paper on the first ascent to the Royal Geographical Society in 1900. The scientific results of his expedition were discussed in detail afterwards.<p>A very curious little bird was found by Mr Jackson on Mount Elgon at a height of 11,000 feet, and I remember saying to Mr. Mackinder that he was bound to find the same sort of little chat on Mount Kenya, at a height of 11,000 feet. This he did, and it was the same species as the Mount Elgon bird, an ordinary-looking little brown chat, with a good deal of white in the tail.<p>The moorland chat was usually placed in the genus Cercomela, but molecular phylogenetic studies published in 2010 and 2012 found that the species was not closely related to birds in Cercomela or to birds in the closely related genus Oenanthe. The moorland chat was therefore assigned to its own monotypic genus Pinarochroa which had been introduced by the Swedish zoologist Carl Jakob Sundevall in 1872. The genus name Pinarochroa is derived from the Greek word pinaros meaning "dirty" and khroos, khroas meaning "coloured". The specific epithet sordida is from the Latin sordidus meaning "shabby" or "dirty".<p>Four subspecies are recognised:

Pechora Pipit
Anthus gustavi
Small, graceful ground-dwelling songbird of open areas with patches of low shrubby cover. Strongly streaked overall with a warm brown back and creamy underparts. Noticeably smaller than Richard's and Paddyfield Pipits, slenderer in appearance than American and Red-throated. Bold black-and-white streaks on back distinguish Pechora from other species. Song is an almost insect-like hard buzzing trill with harsher nasal elements. Call is a hard “tsik.”
White-edged Oriole
Icterus graceannae
Bright orange-and-black bird found in dry forest in western Ecuador and northwestern Peru. The only other oriole in its range is Yellow-tailed Oriole; White-edged lacks yellow on the underside of the tail, has more extensive white in the wing, and is usually (but not always) a deeper orange color. Juveniles are duller and less orange. Forages conspicuously in the trees, and even visits feeders in some areas.
Tanimbar Monarch
Carterornis castus
A striking black-and-white songbird with diagnostic bold white markings on the black face and a broad white panel in the black wings. Outer tail feathers white, and underparts white except for black throat. Female shows more extensive white facial markings and a rose flush to breast. Singles or pairs can be found high in forests of the lowlands and foothills, regularly joining mixed-species flocks. Unique within range in Tanimbar Islands. Song is a stuttering, rising “w’w’witcheuwit.” Also gives a shorter “witcheu” and characteristic monarch rasping calls, “grrrt-grrrt.”
