I don't think you can 'translate' animal languages.

There is nothing to translate, basically.

We can get a good grip of the meaning of their sounds though, if we spend some time listening, but there is no deeper meaning hidden that we can not access.

Experiment on dolphins showed they can explain each other what trick to perform. Can't find the exact experiment but trainer showed the trick to one dolphin and rewarded the pair only when the other dolphin perormed the same trick
