Grauer’s broadbill is one of the rarest and most range-restricted birds in Africa. Found only in a narrow band of montane forest in the Albertine Rift — primarily in eastern Democratic Republic of Congo and marginally in Uganda — it is an extreme rarity and a top target for dedicated birdwatchers visiting Bwindi Impenetrable Forest. In Uganda, sightings are possible but require specialist guidance and significant effort in 2027.
This small, compact forest bird is classified as Vulnerable by the IUCN due to its tiny range and the continued pressure of deforestation on its montane forest habitat. Every sighting in Uganda is therefore both a personal birdwatching achievement and a reminder of the importance of protecting the Albertine Rift forests that Uganda shares with its neighbours.
Identification
Grauer’s broadbill is a small broadbill reaching about 14 centimetres. The male has a distinctive plumage pattern — dark blue-black upperparts, white underparts with a broad blue-black breast band, and a pale blue-green shoulder patch. The bill is broad and flat, characteristic of all broadbills. The female is similar but with a brownish tinge to the upperparts and a less distinct breast band.
The species is most closely related to other African broadbills but its dark and white colour scheme is distinctive within the family. It is most often encountered moving through the forest understorey in pairs or small family groups, often joining mixed-species foraging flocks. Calls are soft and high-pitched, making the species easy to overlook without active searching.
Distribution and Status in Uganda
In Uganda, Grauer’s broadbill reaches the eastern edge of its range in the montane forests of the Albertine Rift, particularly in Bwindi Impenetrable Forest. It is rare and localised even within Bwindi — specialist birding guides who have extensive knowledge of the forest know the areas where the species is most likely to be encountered, but sightings are never guaranteed.
The Ruhija sector of Bwindi, at the highest elevation, is the best area to search. The species prefers the dense, mossy interior of primary montane forest away from disturbed edges. Mixed-species flocks in the forest understorey are worth following carefully as Grauer’s broadbill regularly associates with these flocks.
Habitat and Ecology
Grauer’s broadbill occupies the understorey and middle levels of primary montane forest from approximately 1,600 to 2,500 metres elevation. It appears to prefer areas of dense, structurally complex forest with abundant moss and epiphytes. The species is sensitive to forest disturbance and appears to avoid secondary and degraded forest.
The diet consists of insects and other invertebrates caught by sallying from a perch — the typical broadbill hunting strategy. Little is known about its breeding biology, but nests have the characteristic broadbill structure — a suspended, woven pouch attached to a drooping branch or vine tip. The breeding season likely corresponds to the long rains in Uganda.
Conservation
The primary threat to Grauer’s broadbill is deforestation of montane forest in the Democratic Republic of Congo and adjacent countries. In Uganda the species benefits from the protection of Bwindi as a national park and World Heritage Site. However, its rarity even within protected areas suggests a naturally low population density that makes it inherently vulnerable.
The economic value of birdwatching tourism at Bwindi provides direct conservation incentive. Dedicated birders who visit specifically for Albertine Rift endemics like Grauer’s broadbill contribute financially to the case for maintaining Bwindi’s forest protection. The gorilla permit fees — $800 in 2027 — fund the Uganda Wildlife Authority’s overall conservation programme across all species.
Searching for Grauer’s Broadbill in 2027
If seeing Grauer’s broadbill is a priority for your 2027 Uganda visit, allocate at least two full days of specialist birding at Ruhija. Work with an experienced Bwindi bird guide who knows the species’ current territories. Start very early — before 6am — and follow mixed-species flocks through the forest understorey. The call is your most important tool for locating the species.
Contact us to arrange specialist birding at Bwindi’s Ruhija sector combined with your gorilla trekking permit. Our guides have deep knowledge of where to find Grauer’s broadbill and other extreme rarities in Uganda’s montane forests.
