Records from Gambela,
western Ethiopia
by Claire Spottiswoode and Michael Mills, from Bulletin of the African
Bird Club, volume 7.2, September 2000.
The lowlands of Illubador Province in extreme western Ethiopia have a
fauna and flora, landscape and culture quite distinct from the rest of
the country. Despite easy access to the region, with daily buses and thrice-weekly
flights covering the 500 km between Addis Ababa and Gambela (the second
town of Illubador), it has received surprisingly little ornithological
attention. The only published descriptions of the area's birds appear
to be the recent Ethiopian Important Bird Areas (IBA) directory[5] and
a list of records from the 1970s [3]. These intriguing accounts lured
us to spend 7-12 December 1999 birding around Gambela (08°15'N 34°35'E;
560 m). Despite the lack of a vehicle, we were able to explore the woodland
and river in the immediate vicinity (c10 km radius) of the town reasonably
thoroughly on foot and by bicycle, and recorded several species apparently
new to the region.
Gambela town straddles the Baro River, a reputedly navigable tributary
of the Nile. Close to the town, riparian vegetation has been cleared almost
in its entirety for subsistence agriculture. However, on leaving the town
by bus, we noted considerable untouched riverine forest c40 km to the
east, where the road to Metu rejoins the Baro. In the vicinity of Gambela
town, the Baro flood plain appears relatively narrow, extending no more
than 300 m from the northern bank of the river. During our visit, some
areas were flooded and held reasonable numbers of birds despite disturbance
from grazing cattle.
Vast areas of apparently largely intact dry deciduous woodland cloak the
plains surrounding Gambela. This habitat is varied by occasional rocky
hillocks, scattered termite mounds (supporting thickets) and grassy depressions.
The c1,000 mill annual rainfall occurs principally from May to October,
and our visit thus fell within the dry season. We encountered numerous
large bush fires, fuelled by the 2m-tall understorey grass swathe. These
fires are started by local people and have been previously thought not
to be damaging[1]. A five million ha area to the south and west of Gambela
has been proposed as a conservation area, Gambela National Park [5].

Woodland
Pygmy Sunbird Hedydipna platura appears to have been
hitherto regarded as a vagrant to Ethiopia [7], with no breeding yet recorded
and, in Sudan, occurs only considerably further south and west [4]. We
discovered it to be one of the commonest sunbirds and observed two pairs
nest-building.
Two raptors considered very scarce in Ethiopia were noted: Levant Sparrowhawk
Accipiter brevipes was seen twice in dry woodland c5
km south of the town, and a single Lizard Buzzard Kaupifalco monogrammicus
in moister woodland adjacent to the river.
The woodland also held a number of other species that are local in Ethiopia
and many of which are more characteristically West African. Commonly encountered
species were Little Green Bee-eater Merops orientalis,
Green Wood-hoopoe Phoeniculus purpureus, Green-backed
Eremomela Eremomela pusilla, Foxy Cisticola Cisticola
troglodytes, Yellow-bellied Hyliota Hyliota flavigaster,
Chestnut-crowned Sparrow-weaver Plocepasser superciliosus,
Black-headed Gonolek Laniarius erythrogaster, Black-faced
Firefinch Lagonosticta larvata and Brown-rumped Bunting
Emberiza affinis. Seen once each were Black-billed Wood
Dove Turtur abyssinicus, Swallow-tailed Bee-eater Merops
hirundineus, Brown Babbler Turdoides plebejus,
Gambaga Flycatcher Muscicapa gambagae and Black-rumped
Waxbill Estrilda troglodytes.
