摘要：

The decoding process of distress calls uses many parameters. In our experiment we establish that amplitude modulation was not taken into consideration by the birds in the experiment, even if other parameters were altered. The decoding process that discards amplitude modulation appears well adapted to transmission at long range because amplitude modulation is always subject to degradation.
