Video by @bertiegregory. A pair of black-capped donacobius call to affirm their territory. Top bird nerd fact for the day- this type of singing is known as an antiphonal duet - a behaviour few birds are capable of where two individuals or groups sing alternately at speed with great precision! Unfortunately I wasn't recording sound! Filmed in the southern Pantanal, Brazil, on assignment for @stevewinterphoto, @ナショナルジオグラフィック and @natgeowild. Follow Steve and I (@bertiegregory) for news on our jaguar film coming soon!
