Rare
Under 5% of wildlife watchers report a Long-billed Starthroat sighting in Tayrona National Natural Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 285 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.

GBIF citizen-science records
It is estimated from how often the Long-billed Starthroat is recorded against all the birds logged in Tayrona National Natural Park (21 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.
