sentences:  Gerd Heinrich noted the local name "soisa", meaning drum, and described the call as being a subdued drumming "purre – purre – purre – purre – purre" which sometimes ends in a loud shrill scream.The bird also produced a dull hum similar to the voice of the banded pig ("Sus scrofa vittatus") and reminiscent of the call of the snoring rail ("Aramidopsis plateni").Calling is most frequent in the early morning or late evening, and a human tapping a sago stem with a machete may elicit a response from the bird.
