Trinidad: White-headed Marsh Tyrant

The White-headed Marsh Tyrant, Arundinicola leucocephala, is a small but attractive flycatcher found on Trinidad, but not seen in Tobago or Central America. You can see from the photos why some call it the "Nun". It ranges into South America from Venezuela and Columbia south to Brazil, Bolivia and northern Argentina.


These 5" birds live in or near freshwater marshy areas and hunt from exposed perches, feeding mainly on insects. The male seen here is black, with a white head, whereas the female is dark brown above, and and white underneath. They apparently are heavily parasitized by the Shiny Cowbird.
