Species Description
The Yellow-rumped Munia (*Lonchura flaviprymna*), also known as the Yellow-rumped Mannikin, is a small native finch of northern Australia. Found mainly in the eastern Kimberley region and north-west Northern Territory, this species is adapted to grasslands, wetlands, and moist savannas, where it is often seen in dense stands of tall grasses near swamps and lakes. Despite its subtle colouring compared to other Australian finches, its pale hood and yellow rump make it a distinctive and attractive bird in its preferred habitats.
Fun Facts
Yellow-rumped Munias sometimes form mixed flocks and even hybridize with Chestnut-breasted Munias in overlapping ranges.
1. Pale fawn-white hood contrasting with rufous-brown back and wings
2. Bright yellow rump and golden uppertail-coverts
3. Robust silvery-grey bill and relatively large feet for climbing grass stems
Yellow-rumped Munias breed during the wet season (January–April), building covered, oval nests with side entrances hidden low in tall grass or reeds. Both parents share incubation and care for the young. Their diet is dominated by grass seeds, especially half-ripe seed heads, but also includes sprouted seeds and green plant material. They are highly dependent on the availability of seeding grasses and can be locally common in suitable habitat, but their populations are vulnerable to habitat changes and can fluctuate dramatically.
Yellow-rumped Munias inhabit grasslands, reedbeds, and the edges of swamps and lakes across the Kimberley, Northern Territory, and into north-central Queensland. They prefer areas with tall, dense grasses, especially near water, but can also be found in irrigated agricultural areas such as rice fields. These birds are highly nomadic, moving in response to rainfall and food availability, and are often seen in small, social flocks. During the dry season, they may venture into gardens and more open habitats
