Franklin's gull (Leucophaeus pipixcan) is a small (length 12.6–14.2 in, 32–36 cm) gull. The genus name Leucophaeus is from Ancient Greek leukos, "white", and phaios, "dusky". The specific pipixcan is a Nahuatl name for a type of gull. The English common name was given to commemorate the arctic explorer Sir John Franklin, who led an expedition in 1825 on which the type was collected.
It breeds in central provinces of Canada and adjacent states of the northern United States. It is a migratory bird, wintering in Argentina, the Caribbean, Chile, and Peru. The summer adult's body is white and its back and wings are much darker grey than all other gulls of similar size except the larger laughing gull. The wings have black tips with an adjacent white band. The bill and legs are red. The black hood of the breeding adult is mostly lost in winter.
Young birds are similar to the adult but have less developed hoods and lack the white wing band. They take three years to reach maturity. Measurements: Length: 12.6–14.2 in (32–36 cm) Weight: 8.1–10.6 oz (230–300 g) Wingspan: 33.5–37.4 in (85–95 cm) Although the bird is uncommon on the coasts of North America,... Wikipedia →

Rare
Under 5% of wildlife watchers report a Franklin's Gull sighting in Acadia National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 230th most-seen of the 243 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 Franklin's Gull in Acadia National Park 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 Franklin's 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 parks where we can rate Franklin's Gull sightings, Acadia National Park ranks 23rd at under 5%. The best odds are in Elk Island National Park (Canada, about 50%), Riding Mountain National Park (Canada, about 30%) and Isla del Coco National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Franklin's Gull is recorded against all the birds logged in Acadia National Park (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.
