Shelley’s Crimsonwing Uganda: The Bwindi Finch Rare Species

Shelley’s crimsonwing occurs throughout Bwindi but is most reliably found in specific habitat. Altitude preference: the species prefers mid-to-high altitudes in Bwindi from approximately 1,800-2,800m; the Ruhija sector at higher elevation is generally the most productive site. Ruhija: the highest and most birder-visited sector of Bwindi; the forest here has bamboo, Hagenia, and dense understorey; crimsonwing pairs and small groups are most often found along forest streams and in dense thicket edges. Buhoma: the main visitor entry point for gorilla trekking; lower altitude; crimsonwing is less common here but present; the trail to the waterfall passes through appropriate habitat. Strategy: a dedicated birding morning with a Bwindi birding guide at Ruhija; move slowly through understorey; listen for the soft, liquid call; the bird feeds on grass seeds and tiny insects near the ground and moves in pairs or small groups of 3-5.

Bwindi holds an extraordinary concentration of Albertine Rift endemics. African green broadbill (Pseudocalyptomena graueri): one of Africa’s rarest birds; found only in Bwindi and adjacent DRC; vivid green; sits quietly in mid-canopy; top target species. Grauer’s warbler: endemic to Bwindi and eastern DRC; dense bamboo; very hard to see. Handsome francolin: endemic to the Albertine Rift; forest floor; often heard before seen. Strange weaver: Albertine Rift endemic; forest interior; Bwindi is the most accessible site. Archer’s robin-chat: montane forest; Ruhija area; distinctive call. Kivu ground thrush: endemic; dense forest floor; very secretive. Banded prinia: Albertine Rift; forest edges. Regal sunbird: Albertine Rift endemic; high altitude; brilliant iridescent plumage. Total endemics: Bwindi holds more than 23 Albertine Rift endemic species making it the most important single birding site in East Africa for regional endemics.

The Vulnerable classification reflects a small, fragmented range and specific habitat needs. Range: the total global range covers Bwindi and Mgahinga in Uganda, the Rwenzoris, the Virunga volcanoes and Kahuzi-Biega in DRC, and parts of Rwanda’s Nyungwe Forest; this is a very small total area. Population: the total population is not precisely known; estimated in the low thousands; the DRC population is potentially the largest but DRC forest has suffered severe habitat loss and human pressure. Habitat specificity: the species requires dense, wet montane forest understorey with specific grass and seed species in its diet; degraded forest does not support it. Uganda protection: within Uganda, Bwindi’s formal park status and buffer zone management provides good protection; the population at Bwindi is thought to be stable.

Birding in Bwindi requires an entry permit from Uganda Wildlife Authority but not a gorilla permit. Birding permit: the standard non-gorilla Bwindi entry permit costs USD 40-50 per person per day as of 2027; this covers trail access for birding and forest walks. Gorilla permit: USD 800 per person per trek; needed only if you want to track gorillas; birding visits can be done without this. Birding guide: engaging a specialist Bwindi birding guide is strongly recommended; the forest is dense and species are cryptic; guides who know where individual pairs of crimsonwing or African green broadbill are currently located dramatically improve the sighting rate. Best season for birding: Bwindi birding is good year-round; March-May and September-November when migrants are present and resident birds are breeding are considered peak; the dry season (June-September) is also productive and more comfortable.

Shelley’s crimsonwing is a seed and insect specialist of the forest floor and understorey. Feeding: the crimsonwing feeds primarily on small grass seeds and tiny arthropods; it moves through dense understorey vegetation close to the ground; it gleans insects from leaf surfaces and bark. Pair behaviour: Shelley’s crimsonwing typically moves in monogamous pairs or small family groups; the pair maintains contact with soft contact calls as they move through dense vegetation. Cryptic when alarmed: when disturbed the bird freezes in dense vegetation or flies quickly into deeper cover; patience and slow movement are essential for good views. Morning activity: most active in the early morning from 6am to 10am; the crimsonwing feeds actively at this time before retiring to rest in the heat of the day. Nesting: breeding recorded in Bwindi; the nest is a neat oval structure of grass; exact nesting sites are rarely observed given the secretive nature.
