Instrumental sound

The owl's beak is one of the instrumental sounds

Under an instrumental sound is understood in the Ornithology an utterance that is not through the vocal tract of the bird is generated. Sometimes the sounds are generated with the help of non-body objects, for example when ducks beat their wings on the surface of water.

These include, among other things

• the clatter of bills of some storks ,
• the beak of many birds, but especially owls ,
• the percussion sounds (e.g. the drumming) of the woodpeckers ,
• certain wing noises such as the clapping of the winged pigeon or many goat milkers , the whistling flight noise of the sounding pigeon, the clattering of the wing rattle of the tree rattle lark ( Mirafra ruficinnamomea ) or the burring of wings of many chicken such as chukar , hazel or red grouse and finally
• Feather noises such as the 'bleating' of the common snipe , or the rattling of wings from some cave breeders, especially woodpeckers.
