The double-toothed kite (Harpagus bidentatus) is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found from central Mexico through Central America into much of northern and eastern South America.

GBIF citizen-science records
It is estimated from how often the Double-toothed Kite is recorded against all the birds logged in Brownsberg Nature Park (36 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.
