Ciri fisik

Bulu

Adults have a striking pure white head, nape, and throat, sharply demarcated from the rich chestnut-brown plumage of the back, wings, and underparts. The rump and uppertail coverts are also chestnut-brown, while the tail is dark brown to blackish. The flanks may show faint barring in some individuals.

Bentuk paruh

Conical, stout, and silvery-grey to bluish-grey, adapted for cracking seeds.

Warna mata

Ciri pembeda

The entirely white head contrasting with the dark brown body is the most distinctive field mark. Its small size and typical munia shape (stout bill, short tail) are also characteristic.

Penampilan muda

Juveniles are duller overall, lacking the crisp white head of adults. Their head and underparts are a pale buffy-brown, gradually transitioning to the richer brown of the back and wings. The bill is typically darker, often blackish, and less stout than adults. They acquire adult plumage after their first molt.

Perubahan musiman

No significant seasonal plumage changes. Plumage remains consistent throughout the year.

Dimorfisme seksual

Males and females are monomorphic, appearing identical in plumage. There are no reliable external features to distinguish sexes.

Habitat dan persebaran

Bioma

Tropical and subtropical grasslands, wetlands, agricultural lands.

Persebaran geografis

Native to Southeast Asia, including Malaysia, Indonesia (Sumatra, Java, Borneo, Sulawesi), Singapore, Thailand, Vietnam, Cambodia, Laos, and the Philippines. Introduced to some other regions.

Rentang ketinggian

Typically found from sea level up to approximately 1,500 meters (4,900 feet).

Lingkungan yang disukai

Prefers open country, especially rice paddies, reed beds, tall grass, marshes, and cultivated areas. Also found in gardens and suburban areas where suitable food sources are available.

Perilaku

Waktu aktivitas

Diurnal, most active during the morning and late afternoon.

Kebiasaan makan

Primarily granivorous, feeding on a wide variety of grass seeds, with a strong preference for rice grains, especially during the ripening season. They forage on the ground or cling to seed heads. They often feed in large, cohesive flocks.

Perilaku sosial

Highly gregarious, usually found in flocks ranging from a few individuals to several hundreds, especially outside the breeding season. They roost communally in dense vegetation.

Pola terbang

Flight is typically undulating and direct, often in tight flocks. They are agile fliers, especially when maneuvering through dense vegetation.

Pola migrasi

Resident species throughout its range, with no significant migratory movements. Local movements may occur in response to food availability.

Teritorialitas

Generally not highly territorial, especially when foraging. Breeding pairs may defend a small area around their nest, but flocking behavior remains prominent.

Reproduksi

Musim kawin

Varies geographically, but generally coincides with the rainy season or periods of abundant food, often between April and October in many parts of its range.

Kebiasaan bersarang

Nests are typically globular or dome-shaped structures, loosely woven from grass blades, reeds, and other plant fibers. They are usually placed low in dense vegetation, such as tall grasses, reeds, sugarcane, or small bushes, often near water. Both parents participate in nest building.

Jumlah telur

Typically 4-7 eggs, occasionally up to 10.

Deskripsi telur

Eggs are pure white, smooth, and oval-shaped. Approximately 16-18 mm in length and 11-13 mm in width.

Masa inkubasi

Approximately 13-14 days, incubated by both parents.

Masa terbang

Chicks fledge (leave the nest) around 18-21 days after hatching. They remain dependent on parents for a short period after fledging.

Perawatan orang tua

Both male and female parents share incubation duties and feed the nestlings. They continue to feed the fledglings for some time after they leave the nest.

Tips lapangan

1. Look for Flocks. White-headed Munias are rarely solitary. Scan open areas for groups of small, brown birds, especially near water or cultivated fields.
2. Listen for Calls. Their soft 'chip' or 'tsip' contact calls are often the first indication of their presence, especially when they are foraging in dense vegetation.
3. Observe Feeding Behavior. They often feed on the ground or cling to grass stems to extract seeds. Look for movement in tall grasses or on the ground in open fields.
4. Timing. Best observed during the cooler parts of the day, early morning and late afternoon, when they are most active.
