Possible
About 30% of wildlife watchers report a White-collared Swift sighting in Amboró National Park on a given day, based on 130 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 51st most-seen of the 273 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September and October
In those months about 40% of wildlife watchers report a White-collared Swift in Amboró National Park on a given day, against about 10% in January, April–May and August, the lowest months. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-collared Swift sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 64 parks where we can rate White-collared Swift sightings, Amboró National Park ranks 5th at about 30%, level with the leaders once rounded. The best odds are in Serra dos Órgãos National Park (Brazil, about 30%), Serra da Canastra National Park (Brazil, about 30%) and Pico Bonito National Park (Honduras, about 30%).
GBIF citizen-science records
It is estimated from how often the White-collared Swift is recorded against all the birds logged in Amboró National Park (130 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.
