The grivet (Chlorocebus aethiops) is an Old World monkey with long white tufts of hair along the sides of its face. Some authorities consider this and all of the members of the genus Chlorocebus to be a single species, Cercopithecus aethiops. As here defined, the grivet is restricted to Ethiopia, Sudan, Djibouti, and Eritrea. In the southern part of its range, it comes into contact with the closely related vervet monkey (C. pygerythrus) and Bale Mountains vervet (C. djamdjamensis). Hybridization between them is possible, and may present a threat to the vulnerable Bale Mountains vervet. Unlike that species, the grivet is common and rated as least concern by the IUCN.
The grivet's facial skin, hands, and feet are black. The face has a white line above the eyes. It has long, white whiskers on the cheeks. The fur on the back has an olive color, while the front is white. The skin on the stomach has a blue tint. The fur has a bristly feel. The approximate head and body length for males is 49 cm (19 in) and 42.6 cm (16.8 in) for females. The length of the tail for males is about 30–50 cm (12–20 in). The body mass ranges from 3.4 to 8.0 kg (7.5 to 17.6 lb), with females... Wikipedia →

Possible
About 20% of wildlife watchers report a Grivet sighting in Addis Ababa on a given day, based on 6 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and December
In those months about 50% of wildlife watchers report a Grivet in Addis Ababa on a given day, against under 5% in January, March–April, June–September and November, the lowest months. Those are among Addis Ababa's driest months, with about 50 mm of rain a month against 250 mm in August.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Grivet sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Addis Ababa, in our data
Addis Ababa is the only city on Wallace's Line with enough records to rate Grivet sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Grivet is recorded against all the mammals logged in Addis Ababa (6 verified sightings), 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.
