Bioko Island
I spent a week on Bioko Island in January 2023.
The Caldera (Reserva Científica de la Caldera de San Carlos)
Western Tree Hyrax (Dendrohyrax dorsalis)
Four nights in Moraka Camp inside the reserve produced Drill, Pennant’s Red Colobus, Red-eared and Crowned Monkeys, Ogilby’s Duiker and four species of squirrel: African Giant, Red-legged Sun Squirrel, Green Squirrel and Red-cheeked Rope Squirrel.
Lord Derby’s Anomalure (Anomalurs derbianus)
After dark we saw Lord Derby’s and Beecroft’s Anomaures, Western Tree Hyraxes, Forest Giant Pouched Rat, Allen’s Hylomyscus and Cameroon Soft-furred Mouse.
Malabo
African Straw-coloured Fruit-bats (Eidolon helvum)
There were at least two fruit bat camps in the city in 2023.
Moraka
Angolan Fruit Bat (Myonycteris angolensis)
2 nights in 2023 in the mountain village of Moraka produced Angolan Fruit Bats, several Northern Needle-clawed Galagos and a Red-legged Sun Squirrel.
Pico Basilé National Park
Preuss’s Monkey (Allochrocebus preussi)
During my first morning here in 2023 – walking a trail – I saw nothing. Returning to walk along the road produced several Preuss’s Guenons, a Bioko Hybomys and a Bioko Forest Shrew.
