I also observed a Fasciated Antshrike (Cymbilaimus lineatus) prey on a nest at the mainland site.
The antshrike nest was 2 m from the edge of the vegetation and 2 m above ground.
The return intervals of parents to the nest were not unusually long as Slaty Antshrike parents provision young only a few times per hour.
The antshrike nest (with 2 nestlings) was far from any edge and 1 m in height above ground.
The antshrike nest (with 2 eggs) was on the edge of a small gap and 1.
I was nearby at 1400 hrs when I heard the Slaty Antshrike alarm call.
This is the first observation of a Fasciated Antshrike as a nest predator.
Predators at antshrike nests did not spend more than 2 min at a nest.
The Slaty Antshrike pair vocalized during and after the predation event by the toucan, and adults were aggressive in their nest defense with the Fasciated Antshrike.
