Explore some of Sierra Leone's most interesting natural history locations with us. This sample itinerary is designed to introduce keen nature enthusiasts to the fascinating and still poorly-understood but highly threatened Upper Guinea forest ecoystem.
These forests have been far less visited by tourists than other evergreen forests in Africa, so present nature enthusiasts with an
opportunity to experience something fresh, with forest-dependent species being the focus of the trip. Given the nature of the Upper Guinea forest wildlife and the rudimentary infrastructure at key locations, this is certainly a trip for travel gourmets, rather than gourmands. (As online tour reports serve to indicate, looking for both mammals and birds in Sierra Leone is hard work, but, with the right guiding and organisation in place, people inevitably return satisfied and enthusiastic).
While Gola Rainforest NP and Tiwai Island are certainly (very) far from what can be called 'luxurious', the sites protect some of the last remaining West African rainforests, inhabited by a slew of fascinating mammals, including the likes of Western chimpanzee, Western red and King colobus monkeys and Diana guenon, as well as tiny Royal antelope, Water chevrotain and the bizarre Hammer-headed bat. There's also the near-mythical Pygmy hippo; the Red river hog and some smaller oddities like Bosman's potto and Lord Derby's anomalure. As these rainforests still receive very few ecotourists to help sustain the responsible tourism initiatives under way, you can be sure that your visit really does make a valuable contribution towards protecting these forests.
Primates:
A highlight of Sierra Leone's mammal fauna is its diverse primates. This itinerary - which can be tailored to suit individual interests - will enable you the chance to seek various range-restricted and sometimes Endangered species, such as Diana and Lesser spot-nosed guenons; Upper Guinea colobus (Western red colobus), Sooty mangabey, Campbell's mona monkey and also, King, Western pied and Olive colobus monkeys. The opportunity to seek Western red colobus is especially noteworthy, considering that the Red colobus monkeys (genus Piliocolobus) constitute Africa's most endangered group of primates. Night walks may reveal Thomas' and Demidoff's galagos and West African potto are seen just as regularly, especially on Tiwai.
Ungulates:
Very lucky visitors may glimpse some Duikers (forest-dwelling antelopes, of which the Zebra, Brook's, Maxwell's, Yellow-backed and mega rare Jentink's duiker occur, mostly in Gola) and the tiny, nocturnal Water chevrotain and equally diminutive Royal antelope, which is the smallest of all the world's antelopes. Bear in mind though that all the antelopes have been heavily persecuted for bushmeat so are skittish and scarce. They are best sought during night walks with experienced guides - hard core mammal watchers would do well to bring a thermal scope to assist in locating wildlife.
Rodents and Bats:
A variety of interesting rodents and bats occur in Sierra Leone. Keep a lookout for Gambian; Green, Striped ground and Red-legged sun squirrels. You may also see the very interesting (and quite spectacular) Lord Derby's anomalure (scaly-tailed squirrell), a nocturnal, gliding squirrel which has been recorded in Tiwai close to the accommodation.
Bats present include Straw-coloured and the utterly bizarre (and conspicuously noisy) Hammerhead Fruit bats; Noack's roundleaf bat and Horseshoe bat.
Other mammals:
While at Tiwai island, you might see a Congo clawless otters and perhaps even signs of the ultra elusive Pygmy hippo. While visitors have seen the Pygmy hippos, this is extremely rare, with perhaps a 1% success rate. A bit more likely to be glimpsed are Red river hog and the Common (long-nosed) cusimanse, a curious and social, diurnal mongoose. We must reiterate once more that equatorial West African evergreen forest wildlife is mostly very shy and elusive due to hunting; population densities are low and the dense foliage makes observations more challenging.
Birdlife galore:
Keen birders coming to Sierra Leone are in for a treat: the country isn't very different in size to Scotland, yet more than 640 bird species have been recorded. The most sought-after megatick is of course the White-necked picathartes (rockfowl), for which several nesting caves
are known in Gola. (It can also be sought in the hills near Freetown). 14 of the 15 range-restricted Upper Guinea forest specials can be pursued in Sierra Leone, along with other rarities like Turati's boubou, Emerald starling and the very rare Gola malimbe. (Birders keen to try for Emerald starling and other species present in drier habitats can contact us to tailor itineraries).
Keep a lookout also for the likes of Forbe's plover; Rufous fishing owls, Long-tailed and Standard-winged nightjars; Yellow-casqued, Piping and Brown-cheeked hornbills, White-throated and Black bee-eaters, Shining blue and Blue-breasted kingfishers Yellow-crowned gonolek; Sabine's puffback; iridicsent Splendid, Johanna's and Buff-throated sunbirds and many more feathered gems.
Reptiles and fish:
While work on the reptile, amphibian and fish inventories is ongoing, some 67 reptiles, 35 amphibians and 99 fish species have been recorded
in the country. Among the reptiles, interesting species include Dwarf crocodiles (mangrove habitat) and Slender-snouted crocs along forest
streams. There are some poisonous snakes about, such as Gaboon vipers which have been recorded from time to time in Tiwai. Turtle and Sherbro Islands are known nesting sites for Green and Leatherback turtles.
Other sites in the itinerary:
The itinerary also includes a visit to the very well -run Tacugama Chimpanzee sanctuary and for the marine element, a stay at the Banana Islands makes for a very pleasant and relaxed end to a busy trip.
