Distribution

Region

Mariana Islands

Typical Environment

Historically restricted to lowland wetlands, marshy edges, and dense riparian thickets on Guam. It favored stands of reeds, tall grasses, and secondary growth near freshwater. Birds foraged within tangled vegetation and along stream margins, occasionally venturing into adjacent shrublands. After the mid-20th century, records dwindled rapidly as suitable habitat fragmented and predators proliferated.

Useful to know

Also called the Guam reed-warbler, this species was confined to Guam and is now extinct. It inhabited dense reedbeds and thickets near freshwater, where it delivered a rich, melodious song that inspired its common name. Likely drivers of its extinction include habitat loss and predation from introduced species, especially the brown tree snake.

Behaviour

Temperament

solitary and territorial

Flight Pattern

short rapid wingbeats, usually low over vegetation

Social Behavior

Typically maintained territories in dense cover and was seldom seen in large groups. It nested low in reeds or shrubs, building a cup-shaped nest supported by stems. Pairs were likely monogamous during the breeding season, with both adults feeding the young.

Migratory Pattern

Resident

Song Description

A rich, varied warble with liquid notes, whistles, and trills, delivered from concealed perches or low song posts. The song was persistent during the breeding season and carried well over wetlands.

Nihoa finch

The Nīhoa finch is one of the two endemic bird species of the tiny Hawaiian island of Nīhoa, the other being the Nīhoa millerbird. The island's population is 1000–3000 birds. The Nīhoa finch was added to the Endangered Species List by the U.S. Fish and Wildlife Service on March 11, 1967. An attempt to protect the species against extinction was made by starting a colony on French Frigate Shoals, another leeward island. This would ensure its continued existence in case the Nīhoa population was wiped out. This attempt, however, failed. Nīhoa is part of a group of islands that make up the Hawaiian Islands National Wildlife Refuge which provides protected land for the Nīhoa finch to roam on.

Nilgiri blue robin

The Nilgiri blue robin, also known as Nilgiri shortwing, white-bellied shortwing, Nilgiri sholakili or rufous-bellied shortwing is a species of passerine bird in the family Muscicapidae endemic to the Shola forests of the higher hills of southern India, mainly north of the Palghat Gap. This small bird is found on the forest floor and undergrowth of dense forest patches sheltered in the valleys of montane grassland, a restricted and threatened habitat.

Nilgiri flowerpecker

The Nilgiri flowerpecker 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 in India. 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.

Nilgiri flycatcher

The Nilgiri flycatcher is an Old World flycatcher with a very restricted range in the hills of southern India. It was formerly referred to as the Nilgiri verditer flycatcher because of its similarity to the verditer flycatcher, a winter migrant to the Nilgiris, which, however, has distinct dark lores and a lighter shade of blue. There are two small white patches at the base of the tail. It is found mainly in the higher altitude shola forests of the Western Ghats and the Nilgiris.

Nilgiri laughingthrush

The Nilgiri laughingthrush is a species of laughingthrush endemic to the high elevation areas of the Nilgiris and adjoining hill ranges in Peninsular India. The mostly rufous underparts, olive brown upperparts, a prominent white eyebrow and a black throat make it unmistakable. It is easily detected by its loud series of nasal call notes and can be hard to spot when it is hidden away inside a patch of dense vegetation. The species has a confusing taxonomic history, leading to a range of names. In the past the species was considered to have two subspecies, the nominate form in the Nilgiris and jerdoni with a grey upper breast and found in the Brahmagiris of Coorg and Banasura range of Wayanad. They are omnivorous, feeding on a range of insects, berries and nectar.
