Rare
Under 5% of wildlife watchers report a Laughing Gull sighting in Chicago on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 284th most-seen of the 314 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Laughing Gull in Chicago on a given day, so our monthly data shows no clear season.
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.
23rd of 24
Of the 24 cities where we can rate Laughing Gull sightings, Chicago ranks 23rd at under 5%. The best odds are in Havana (Cuba, about 40%), Panama City (Panama, about 30%) and New York City (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Laughing Gull is recorded against all the birds logged in Chicago (18 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.
