Bwindi’s Birds — Why the Forest Is One of Africa’s Birding Destinations
Bwindi Impenetrable National Park’s bird list of approximately 350 species is one of the most remarkable avian tallies of any protected area in East Africa — not because 350 species is exceptional by African forest standards, but because of the composition of that list: more than 23 species that are restricted in their range to the Albertine Rift (the great escarpment zone running from Uganda’s Rwenzori through Rwanda and Burundi to the eastern DRC), including several species that are found essentially only in Bwindi within Uganda. The Albertine Rift endemic concentration at Bwindi makes it the single most important site in Uganda for accessing the endemic bird zone that is the defining ornithological character of the Great Rift Valley’s western escarpment.
The Albertine Rift Endemics — The Key Species
The African green broadbill (Pseudocalyptomena graueri) is Bwindi’s most sought-after bird — a brilliant emerald-green forest floor species of such restricted range and specific habitat requirement that Bwindi and the adjacent Bwindi-Sarambwe corridor represent its most reliable access point in Uganda. The species feeds on berries in the forest understory at the mid-altitude forest where the Buhoma and Ruhija sectors overlap, and its relatively confident behaviour (for an endemic that is regularly persecuted by collectors in areas outside Uganda’s protection) makes patient morning observation in the right habitat reliably rewarding.
Shelley’s crimsonwing (Cryptospiza shelleyi), the Bwindi warbler (Bradypterus lopezi, until recently considered a subspecies of the African scrub warbler), the handsome francolin, the dwarf honeyguide, the black-faced apalis, the Grauer’s broadbill, and the Ruwenzori apalis are among the species that make the Ruhija sector of Bwindi the most productive single site for Albertine Rift endemics in Uganda. A dawn birding walk from the Ruhija ranger post with a specialist guide can produce twelve to fifteen Albertine Rift endemics in a single morning session.
Forest Floor Specialists
Bwindi’s forest floor bird community — the species that feed and move in the leaf litter and low vegetation layer rather than in the canopy — includes several that are easier to observe in Bwindi than at most other Uganda forest sites: the African pitta (a spectacular but elusive species present between October and April as an intra-African migrant), the forest robin, and the various thrushes and ground-flycatchers that move through the litter layer during the quiet mid-morning hours. The forest floor is best accessed via the longer forest trails (the Muzabajiro Loop and the Waterfall Trail at Buhoma, the Muyanga River Trail at Ruhija) rather than the main approach tracks that the gorilla trekking groups use.
Combining Gorilla Trekking and Birding at Bwindi
The gorilla trekking morning occupies the prime morning birding window — the first four to six hours after dawn that produce the most active forest bird activity. Visitors who want both gorilla trekking and serious Bwindi birding therefore need either multiple Bwindi days (the gorilla trek day and at least one pure birding day) or the willingness to accept that the gorilla trek morning’s birding is opportunistic rather than structured. On the return walk from a gorilla encounter, with the group’s attention shifted from family-finding to landscape observation, the birding quality can be excellent — the same route walked differently, with a birding guide, is often a very productive morning’s bird list even as a secondary activity after the gorilla morning.
