Rare
Under 5% of wildlife watchers report a Seaside Sparrow sighting in Everglades National Park on a given day, based on 87 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 203rd most-seen of the 273 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Seaside Sparrow in Everglades National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Seaside Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Seaside Sparrow sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Seaside Sparrow is recorded against all the birds logged in Everglades National Park (87 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.
