Cephalophus callipygus
In 3 days ~60% in a week ~90%
Peters' duiker (Cephalophus callipygus) is a small antelope found in Gabon, Equatorial Guinea, southern Cameroon, and northern Republic of the Congo. Peters' duikers typically weigh about 40 lb (18 kg), and are about 20 in (50 cm) at the shoulder. They have grey-brown coats, and live in dense undergrowth in mountain rainforests. Peters's duikers are a diurnal species, with peak activity between dawn and dusk.
The total population is estimated at 380,000 individuals, with a declining trend. Habitat loss and poaching are considered the main drivers of this decline, particularly poaching through snare traps targeting the animal for bushmeat. This is despite protective measures in some national parks. Wikipedia →

Possible
About 30% of wildlife watchers report a Peters' Duiker sighting in Odzala-Kokoua National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 32 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
November
In that month about 60% of wildlife watchers report a Peters' Duiker in Odzala-Kokoua National Park on a given day, against under 5% in January–February and April–August, the lowest months. That is one of Odzala-Kokoua National Park's wettest months, with about 190 mm of rain against 50 mm in January.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Peters' Duiker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Odzala-Kokoua National Park, in our data
Odzala-Kokoua National Park is the only park on Wallace's Line with enough records to rate Peters' Duiker sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Cephalophus
The closest relatives of the Peters' Duiker that you can see in Odzala-Kokoua National Park (genus Cephalophus, Forest Duikers) are Black Fronted Duiker (about 30%), Light-backed Duiker (about 20%) and Bay Duiker (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Peters' Duiker is recorded against all the mammals logged in Odzala-Kokoua National Park (13 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
