Stridulated soft
song by singing insects
The soft vocalizations of many of these animals,
including birds and mammals, have proven to be extremely difficult to collect
data on due to difficulty in hearing and recording such songs in the wild, the
lack of production of these sounds in captivity, and the difficulty in
standardizing measurements of the amplitude produced by free-moving animals.
For instance, some species of moths produce extremely quiet ultrasonic
courtship songs without also producing a high-amplitude song, and field
crickets sing courtship songs that
contain both relatively loud and quiet elements within the same song.
