Rare
Under 5% of wildlife watchers report a Chestnut-collared Swift sighting in Tayrona National Natural Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 240th most-seen of the 285 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 Chestnut-collared Swift in Tayrona National Natural Park on a given day, so our monthly data shows no clear season.

Of the 31 parks where we can rate Chestnut-collared Swift sightings, Tayrona National Natural Park ranks 26th at under 5%. The best odds are in El Triunfo (Mexico, about 10%), Podocarpus National Park (Ecuador, about 10%) and Henri Pittier National Park (Venezuela, under 5%).
GBIF citizen-science records
It is estimated from how often the Chestnut-collared Swift is recorded against all the birds logged in Tayrona National Natural 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.
