Double-toothed Kite is a big cause of misidentification.


South America: from the Guianas south to eastern Bolivia, Paraguay, southern Brazil and northern Argentina.


This is a monotypic species1.


Primary lowland rain forests.



The diet consists mostly of insects, particularly cicadas, small birds and lizards.


This seems to be a migrant breeding in austral summer in Atlantic Forest of Brazil as well as in eastern Bolivia (cerrado areas) and vacating the southernmost part of this range in austral winter which is spent in Amazonian areas.
