Black-headed (Chestnut) Munias live in pairs or small flocks when breeding and large social groups outside of the breeding season; they gather in rushes and tall grasses to roost in flocks. Breeding birds and recent fledglings roost in nests. Non-breeding birds may mingle with Spotted Munias. Feeds primarily on the ground and from seeding grasses. Considered a pest on rice paddy fields.
