Mr. Salvin gives the following note on the peculiar sound 
that this bird makes when on the wing. He says :—“I well 
remember being startled by a strange sound when shooting in 
one of the ravines in the Volcan de Agua in Guatemala. Not 
at first perceiving whence it arose, I walked on, when the noise 
was again repeated. I then set about discovering the cause, 
and soon found that it was produced by a male Penelopina 
nigra which, when flying in a downward direction with out- 
stretched wings, gave forth a kind of crashing, rushing noise 
which I likened at the time to the falling of a tree,”
