The pennant-winged nightjar (Caprimulgus vexillarius) is a species of nightjar that occurs from Nigeria to northern South Africa. It is an intra-African migrant and displays remarkable sexual dimorphism in the breeding season.
Their preferred habitat south of the equator is plateau woodlands, especially Miombo, where they are partial to stony or boulder-strewn hillsides. They are observed as bi-annual and social passage migrants along the Kenyan Rift Valley and Lake Victoria regions, and spend the non-breeding season in subtropical savanna from Nigeria to Sudan.
The male of the species is characteristic in having a broad white band over the otherwise black primaries. In addition the males acquire a striking 2nd primary feather during the breeding season. These pennant feathers grow to greater lengths in successive years, up to twice the body length. They are dropped or broken off quickly upon completion of breeding. With the distal (9th) and proximal (1st - 3rd) primaries being longest, the wings of male birds are distinctly angular.
Foraging birds emerge in the late afternoon or directly after sunset for crepuscular feeding and... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pennant-winged Nightjar sighting in Lake Mburo National Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 233rd most-seen of the 362 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April, July and October
In those months about 10% of wildlife watchers report a Pennant-winged Nightjar in Lake Mburo National Park on a given day, against under 5% in May–June, August–September and November–March, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Pennant-winged 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.
Among the best
Of the 12 parks where we can rate Pennant-winged Nightjar sightings, Lake Mburo National Park ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Mana Pools National Park (Zimbabwe, under 5%), Murchison Falls National Park (Uganda, under 5%) and Kafue National Park (Zambia, under 5%).
Same genus: Caprimulgus
The closest relatives of the Pennant-winged Nightjar that you can see in Lake Mburo National Park (genus Caprimulgus, Old World Nightjars) are Fiery-necked Nightjar (about 10%), Freckled Nightjar (about 10%) and Square-tailed Nightjar (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pennant-winged Nightjar is recorded against all the birds logged in Lake Mburo National Park (38 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.
