The little tern (Sternula albifrons) is a small seabird of the family Laridae. It is widely distributed breeding on the coasts and inland waterways of Europe, Asia, north and west Africa, and eastern Australia. It winters in the subtropical and tropical oceans as far south as South Africa and Australia.
The little tern was formally described in a sales catalogue by the German naturalist Peter Simon Pallas in 1764 under the binomial name Sterna albifrons. The type locality is Holland in the Netherlands. The species was moved to the genus Sternula when the genus Sterna was restricted to the larger typical terns. The genus name Sternula is a diminutive of Sterna, 'tern', while the specific name albifrons is from Latin albus, 'white', and frons, 'forehead'.

Rare
Under 5% of wildlife watchers report a Little Tern sighting in Tangkoko Nature Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 138 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.
September
In that month about 10% of wildlife watchers report a Little Tern in Tangkoko Nature Reserve on a given day, against under 5% in October to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Little Tern sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 24
Of the 24 parks where we can rate Little Tern sightings, Tangkoko Nature Reserve ranks 18th at under 5%. The best odds are in Bali Barat National Park (Indonesia, about 30%), Sundarbans National Park (India, about 20%) and Yala National Park (Sri Lanka, about 20%).
GBIF citizen-science records
It is estimated from how often the Little Tern is recorded against all the birds logged in Tangkoko Nature Reserve (9 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.
