The montane nightjar (Caprimulgus poliocephalus), mountain nightjar or Abyssinian nightjar, is a species of nightjar in the family Caprimulgidae. It is native to upland regions of Central and Eastern Africa where it is a locally common species.
The Montane nightjar was originally described by the German naturalist Eduard Rüppell in 1840. He used the current binomial name Caprimulgus poliocephalus. The subspecies C. p. ruwenzorii was formerly sometimes treated as a separate species, the Ruwenzori nightjar. Although a molecular genetic study of these four nightjars has not been published, the results of the detailed measurement of museum specimens suggests that they should be considered as conspecific.
The montane nightjar is a rather dark nightjar growing to a length of about 23 cm (9.1 in). It has somewhat tawny, blackish or chocolate brown... Wikipedia →

No species of the same family or order lives in Nairobi, so these are its closest relatives here: other birds.
With luck
About 10% of wildlife watchers report an Abyssinian Nightjar sighting in Nairobi on a given day, based on 155 verified sightings from GBIF citizen-science data. It is the 92nd most-seen of the 234 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June–October and December–January
In those months about 10% of wildlife watchers report an Abyssinian Nightjar in Nairobi on a given day, against under 5% in February–May and November, the lowest months.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Abyssinian Nightjar sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 2 cities where we can rate Abyssinian Nightjar sightings, Nairobi has the highest daily chance: about 10%. Next come Addis Ababa (Ethiopia, under 5%).
GBIF citizen-science records
It is estimated from how often the Abyssinian Nightjar is recorded against all the birds logged in Nairobi (155 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.
