The white-chinned swift (Cypseloides cryptus) is a species of swift in the family Apodidae. It is found from Mexico south through most Central America countries into South America as far south as Peru and east as far as Suriname.
The white-chinned swift is monotypic. Some authors consider it and the white-fronted swift (Cypseloides storeri) to form a superspecies. Others consider it more closely related to the sooty swift (C. fumigatus) and Rothschild's swift (C. rothschildi) or that all three of them are a single species.
The white-chinned swift is about 15 cm (5.9 in) long and weighs about 35 g (1.2 oz). The sexes are alike. They have a dark brown crown and cheeks, a short white streak above the eye, a white chin, and a dark brown throat. Their back and rump are blackish brown and the wings and tail slightly darker. Their undersides are paler than the back and rump and the underside of the wing is paler than the upper side.
The white-chinned swift is widely but very patchily distributed. It has been confirmed to nest only in Costa Rica and at one location in northern Brazil. There are sight records in... Wikipedia →

Rare
Under 5% of wildlife watchers report a White-chinned Swift sighting in San José on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 309th most-seen of the 379 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 White-chinned Swift in San José on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-chinned Swift sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only San José, in our data
San José is the only city on Wallace's Line with enough records to rate White-chinned Swift sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-chinned Swift is recorded against all the birds logged in San José (12 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.
