Fan-tailed Widowbird: The Bouncing Black Display Bird of East Africa’s Grasslands
The fan-tailed widowbird is a common and conspicuous bird of East Africa’s open grassland, flooded fields, and marshy grassland zones. The breeding male is jet black with a vivid red and white shoulder patch. He performs a slow, bouncing display flight low over his territory that makes him one of the most visible grassland birds in the region during the breeding season.
Unlike several other widowbird species with dramatically elongated tails, the fan-tailed widowbird carries a relatively short, broad tail that is fanned during the display flight to show its full width. The combination of the black plumage, the coloured shoulder patches, and the distinctive bouncing flight makes the displaying male unmistakable in any open grassland environment where it occurs.
Identification
The breeding male fan-tailed widowbird is completely black with a red shoulder patch bordered by white. The tail is short and broad compared to most widowbird species. The bill is pale blue-grey and relatively heavy for the bird’s size. The black plumage in direct sunlight shows a slight iridescent sheen on the wings and back.
The non-breeding male moults out of black plumage into a streaked brown pattern similar to the female. The shoulder patch remains visible but is duller and less defined. Non-breeding males are considerably more difficult to identify than the conspicuous black breeding birds.
The female is a streaked brown bird with a pale supercilium. She nests in the grassland and is cryptically coloured to avoid detection at the nest. The pale supercilium and the heavier bill distinguish her from the very similar non-breeding male and from the females of other brown grassland birds sharing her habitat.
Display Behaviour
The male’s display flight is one of East Africa’s grassland’s most characteristic visual experiences during the breeding season. He rises from a grass stem, fans his tail to show its full width, fluffs his shoulder patches, and bounces slowly across his territory in an exaggerated up-and-down flight path at 2 to 5 metres above the grass.
The bouncing rhythm is slow and deliberate. The male rises and falls rhythmically as he traverses his territory perimeter. He calls simultaneously with a series of harsh, buzzing notes that carry across the open grassland and announce his territorial occupation to neighbouring males.
The territory size varies with population density. In areas with high male density, territories are small and the boundaries are aggressively defended. In sparser populations, territories are larger and males spend more time in display flight. A single male may mate with multiple females nesting within his territory during one breeding season.
Habitat and Distribution
Fan-tailed widowbirds inhabit open grassland, seasonally flooded grassland, moist cultivation edges, and the edges of papyrus and reedbed wetlands. The species requires both dense grassland for nesting and some open bare or short-grass areas for ground foraging.
The species is common across a wide band of East Africa from Uganda southward through Kenya and Tanzania wherever suitable grassland habitat exists. Uganda’s open grassland areas in Queen Elizabeth National Park, Kenya’s Rift Valley grasslands, and Tanzania’s highland grasslands above 1,500 metres all carry fan-tailed widowbird populations.
The species is particularly abundant in the Lake Victoria basin’s seasonally flooded grassland areas where the combination of tall nesting grass and flooded foraging substrate provides ideal habitat. Ugandan grassland areas near the lake shore carry the highest densities in East Africa.
Plan Your Birding Safari
Fan-tailed widowbird sightings require open grassland destinations and the right season. The species is most conspicuous during the breeding season when males are in full black plumage and performing their display flights. This typically coincides with the long and short rains in East Africa between March to June and October to December.
Uganda’s open grassland areas and Kenya’s Rift Valley grasslands provide the most reliable fan-tailed widowbird encounters within established safari circuits.
