The laughing gull was long placed in the genus Larus until its present placement in Leucophaeus.
The laughing gull was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Larus atricilla.

Rare
Under 5% of wildlife watchers report a Laughing Gull sighting in Caroni Swamp on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 128th most-seen of the 169 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.
February–March and October
In those months about 10% of wildlife watchers report a Laughing Gull in Caroni Swamp on a given day, against under 5% in April–September and November–January, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Laughing Gull sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
35th of 44
Of the 44 parks where we can rate Laughing Gull sightings, Caroni Swamp ranks 35th at under 5%. The best odds are in Padre Island National Seashore (United States, about 90%), Ría Lagartos Biosphere Reserve (Mexico, about 90%) and Celestún Biosphere Reserve (Mexico, about 70%). All parks ranked.
Same family: Laridae
The closest relatives of the Laughing Gull that you can see in Caroni Swamp (family Laridae, Gulls, Terns, and Skimmers) are Large-billed Tern (about 10%) and Black Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Laughing Gull is recorded against all the birds logged in Caroni Swamp (27 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.
