Rare
Under 5% of wildlife watchers report a Thick-billed Vireo sighting in Miami on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 245th most-seen of the 325 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 Thick-billed Vireo in Miami on a given day, so our monthly data shows no clear season.
Only Miami, in our data
Miami is the only city on Wallace's Line with enough records to rate Thick-billed Vireo sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Thick-billed Vireo is recorded against all the birds logged in Miami (56 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.
