The Indian nightjar (Caprimulgus asiaticus) is a small nightjar which is a resident breeder in open lands across South Asia and Southeast Asia. Like most nightjars it is crepuscular and is best detected from its characteristic calls at dawn and dusk that have been likened to a stone skipping on a frozen lake - a series of clicks that become shorter and more rapid. They are sometimes spotted on roads when their eyes gleam red in the spotlight of a vehicle. There is considerable plumage variation across its range and can be hard to differentiate from other nightjars in the region especially in the field.

Rare
Under 5% of wildlife watchers report an Indian Nightjar sighting in Thrissur on a given day, based on 44 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 217 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report an Indian Nightjar in Thrissur on a given day, against under 5% in March to January, the lowest months. That is one of Thrissur's driest months, with about 20 mm of rain against 440 mm in June.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Indian Nightjar sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 16 cities where we can rate Indian Nightjar sightings, Thrissur ranks 7th at under 5%, level with the leaders once rounded. The best odds are in Solapur (India, under 5%), Chhatrapati Sambhajinagar (India, under 5%) and Raipur (India, under 5%).
Same genus: Caprimulgus
The closest relatives of the Indian Nightjar that you can see in Thrissur (genus Caprimulgus, Old World Nightjars) are Jerdon's Nightjar (about 20%) and Savanna Nightjar (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Indian Nightjar is recorded against all the birds logged in Thrissur (44 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.
