The pearl kite (Gampsonyx swainsonii) is a very small raptor found in open savanna habitat adjacent to deciduous woodland in Central and South America. It is the only member of the genus Gampsonyx. The scientific name commemorates the English naturalist William Swainson.
The type specimen was collected from Brazil by English naturalist William Swainson, and described by Nicholas Aylward Vigors in 1825. Vigors noted the similarity to both hawks and falcons, but placed Gampsonyx within the "Accipitrine subfamily" because it lacks the notched beak of the falcons. He also noted its striking resemblance to the coloration of the falconets.
Later, the pearl kite was classified with the falcons. For example, Peters placed it with the forest falcons in subfamily Polyhieracinae. In the mid-20th century it was found to be related to Elanus based on morphology and its molt schedule.
This tiny kite breeds from Panama, Colombia and Venezuela south to Bolivia and northern Argentina, with an isolated sedentary population in Nicaragua. It is expanding its range and was proved to breed on Trinidad in 1970. It was first reported in Costa Rica... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pearl Kite sighting in Santa Rosa National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 208th most-seen of the 233 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.
April
In that month about 10% of wildlife watchers report a Pearl Kite in Santa Rosa National Park on a given day, against under 5% in May to March, the lowest months. That is one of Santa Rosa National Park's driest months, with about 35 mm of rain against 450 mm in October.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Pearl Kite 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 8 parks where we can rate Pearl Kite sightings, Santa Rosa National Park ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Tayrona National Natural Park (Colombia, under 5%), Henri Pittier National Park (Venezuela, under 5%) and Parque Natural Metropolitano (Panama, under 5%).

GBIF citizen-science records
It is estimated from how often the Pearl Kite is recorded against all the birds logged in Santa Rosa National Park (8 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.
