The savanna nightjar (Caprimulgus affinis), also known as allied nightjar or Franklin's nightjar, is a species of nightjar found in South and Southeast Asia. The IUCN Red List has assessed the species to be of least concern because it has a large range and its population trend is stable. As other nightjars, this nocturnal bird is characterised by its large eyes, gaping mouth and excellent camouflage. It can be distinguished from similar south Asian nightjar species, like the chirruping nightjar, by its unique vocalisations.
The savanna nightjar belongs to the diverse family Caprimulgidae along with 89 other species, 39 of which share the genus Caprimulgus. Wikipedia →

With luck
About 10% of wildlife watchers report a Savanna Nightjar sighting in Surabaya on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 23rd most-seen of the 27 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.
May and July–October
In those months about 10% of wildlife watchers report a Savanna Nightjar in Surabaya on a given day, against under 5% in November to March, the lowest months. Those are among Surabaya's driest months, with about 50 mm of rain a month against 330 mm in January. April and June have too few records to rate.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Savanna Nightjar sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 20
Of the 20 cities where we can rate Savanna Nightjar sightings, Surabaya ranks 9th at about 10%. The best odds are in Makassar (Indonesia, about 20%), Padang (Indonesia, about 10%) and Denpasar (Indonesia, about 10%).
GBIF citizen-science records
It is estimated from how often the Savanna Nightjar is recorded against all the birds logged in Surabaya (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.
