Nilgiri flowerpecker

The Nilgiri flowerpecker (''Dicaeum concolor'' in the wider sense) is a tiny bird in the flowerpecker family. Formerly a subspecies of what used to be termed as the plain flowerpecker although that name is now reserved for ''Dicaeum minullum''. Like others of the group, it feeds predominantly on nectar and fruits. They forage within the canopy of forests and are found distributed across South and Southeast Asia. They are non-migratory and the widespread distribution range includes several populations that are non-overlapping and morphologically distinct, some of which are recognized as full species. They are important pollinators and dispersers of mistletoes in forests.
==Description==
These birds are tiny (9 cm long) and there is no marked difference between the males and females. The nominate race is found in hill forests of the Western Ghats and Nilgiri hills of southern India. This population is separated widely from the other populations in Southeast Asia. This subspecies is pale brown on the upperside and the underside is whitish. The whitish brow in front of the eye is wider than in ''Dicaeum erythrorhynchos''. This subspecies has been raised to full species by Pamela Rasmussen. The subspecies found in northeastern India, extending into Myanmar, Laos and southern China is called ''olivaceum'' by earlier authors but is treated by Rasmussen as a separate species ''Dicaeum minullum'' (which includes the population ''minullum'' from Hainan Island and is now termed as the plain flowerpecker in the more restricted sense). This is very olive above and the black bill is finer and slightly curved. The population found in the Andaman Islands ''virescens'' is also considered a separate species ''Dicaeum virescens'' (the Andaman flowerpecker) in the newer treatment. This is bright olive-green on the upperside with dark speckling on the crown. The centre of the belly has a bright patch of pale yellow. Other populations include ''borneanum'' of Peninsular Malaysis, Sumatra and Borneo, ''uchidai'' of Taiwan and ''sollicitans'' from the islands of Java.
