Distribution

Region

New Guinea

Typical Environment

Occurs across the northern and eastern lowlands of New Guinea, frequenting freshwater marshes, swamps, and lake margins. It favors dense reedbeds, tall grasses, and sedge-dominated wetlands, and readily uses rice paddies and seasonally flooded fields. Birds are often seen along slow rivers, oxbow lakes, and sago swamps. They perch low, moving between seed-laden stems and the ground to forage.

Useful to know

Also called the grand munia, this estrildid finch is endemic to New Guinea’s northern and eastern lowlands. Its oversized, powerful bill is adapted for cracking tough grass and sedge seeds. It often forms flocks in wetlands and rice fields and roosts communally in dense reeds. Although assessed as Least Concern, local wetland drainage can affect its habitat.

Behaviour

Temperament

social and active

Flight Pattern

short rapid wingbeats with undulating, bounding flight over reeds

Social Behavior

Typically found in small to medium flocks outside the breeding season, often mixing with other munias. Pairs nest in dense vegetation, constructing globular grass nests low in reeds or tall grasses. They may breed semi-colonially where suitable habitat is continuous. Communal roosting in reedbeds is common.

Migratory Pattern

Resident

Song Description

Soft, high-pitched twitters and trills with thin tsip calls used for contact in flocks. The song is modest and repetitive, delivered from a perch within reeds or grasses.

Greater adjutant

The greater adjutant is a member of the stork family, Ciconiidae. Its genus includes the lesser adjutant of Asia and the marabou stork of Africa. Once found widely across southern Asia and mainland southeast Asia, the greater adjutant is now restricted to a much smaller range with only three breeding populations; two in India, one in the north-eastern state of Assam and a smaller one around Bhagalpur; and another breeding population in Cambodia. They disperse widely after the breeding season. This large stork has a massive wedge-shaped bill, a bare head and a distinctive neck pouch. During the day, it soars in thermals along with vultures with whom it shares the habit of scavenging. They feed mainly on carrion and offal; however, they are opportunistic and will sometimes prey on vertebrates. The English name is derived from their stiff "military" gait when walking on the ground. Large numbers once lived in Asia, but they have declined to the point of endangerment. The total population in 2008 was estimated at around a thousand individuals. In the 19th century, they were especially common in the city of Calcutta, where they were referred to as the "Calcutta adjutant" and included in the coat of arms for the city. Known locally as hargila and considered to be unclean birds, they were largely left undisturbed but sometimes hunted for the use of their meat in folk medicine. Valued as scavengers, they were once depicted in the logo of the Calcutta Municipal Corporation.
