Crocodile Talk |
Crocodilians are the most vocal of all reptiles, and calls vary widely depending on species, age, size and sex. Context is also very important, and some species can communicate over 20 different kinds of messages through sound alone. But just what are they saying? |
Learn to speak croc in under 5 minutes! First select the species you prefer, then choose a call type. Click on either or to download the sounds. Click on this colourful icon in the "Learn More" column, and you'll be able to "see" that particular crocodile sound! These are called "spectrograms" and they show the change in frequency over time. With each spectrogram is a description of the sound, what the animal does when it produces it, and a "translation" into English! More spectrograms are being added all the time. All sounds are MONO. In most cases, the 8-bit samples are almost as good as the 16-bit versions, although the upper frequency of some calls is lost in 22 KHz playback. 16-bit is for fast connections, perfectionists or very patient people! All files are in .WAV format - this is the standard PC file format, but Mac owners should be able to convert it automaticaly with their browser. Bandwidth of microphone used: 100 Hz - 20,000 Hz. This is fine for most juvenile calls, but the very low frequencies and of course infra-sonic frequencies used by bellowing adults are lost. All sounds digitally recorded on DAT. Spectrograms produced using SoundAlyze / BatSound by Pettersson Electronics. SPECIES LIST BIOLOGY DATABASE INTERNET LINKS |
