Southern Red Bishop

The Southern Red Bishop is a small, sparrow-sized member of the weaver family widespread across sub-Saharan Africa, closely tied to marshes, reedbeds, and rank grassland near water. Its common name comes from the striking transformation the breeding male undergoes.

In breeding plumage, the male is unmistakable: brilliant scarlet-red covering the crown, face-surround, back, and rump, contrasting with a black face, throat, and belly. Outside the breeding season, males molt into a cryptic sparrow-like brown, heavily streaked plumage similar to the female, which is dull brown and streaky year-round.

The species is highly polygynous, with dominant males holding reedbed territories where several females may nest.

Key field marks

• Breeding male: scarlet-red crown, mantle, and rump with a contrasting black face, throat, and belly
• Non-breeding male and female: streaky brown, sparrow-like, with a stout conical bill
• Short, rounded wings and a fairly short tail
• Often seen flying low and fast over reedbeds during the breeding season

Similar species

• Yellow-crowned Bishop shows golden-yellow rather than red on the crown and rump in breeding male plumage.
• Fire-fronted (Zanzibar) Bishop and other red-plumaged bishops have more restricted ranges and subtly different patterns of black on the face.
• Female and non-breeding males of all bishop species are very similar and best separated by range, bill shape, and associating breeding males nearby.

Range

Widespread across sub-Saharan Africa, from Senegal east to Ethiopia and south through East and southern Africa to South Africa.

Habitat

Favors wetlands, marshes, reedbeds, rank grass along rivers and dams, and adjacent grassland or agricultural fields, especially during the non-breeding season when it forms large foraging flocks.

Movements

Mostly resident, though some local and seasonal movements occur in response to water availability and food supply, with birds sometimes forming large nomadic flocks outside the breeding season.

Behavior

Highly gregarious outside the breeding season, forming large mixed flocks with other seed-eating birds. During breeding, males become territorial and aggressively defend clusters of nest sites within a reedbed colony.

Voice

Gives sharp chirping and buzzing notes, along with a wheezy, chattering song often delivered during display flights over the breeding territory.

Feeding

Feeds mainly on grass and other seeds, taken from the ground or directly from seedheads, and also eats insects, especially when raising young.

Nesting and breeding

The male weaves several oval, woven nests of grass and reed strips attached to reed stems within his territory, then displays to attract females, who choose a nest and line it themselves. The species is polygynous, with a successful male mating with multiple females across the breeding season, each raising a brood independently.
