Not a language model, but there was this classifier mapping pig squeals to contextual information about the animal [1].

For human language models there are obvious practical uses and we can intuitively evaluate the quality of the models. For animal communication you need to use other biological variables, like valence in the pig communication example.

I do remember one where they generated artificial frog mating calls and were able to generate artificial ones that were exceptionally attractive to female frogs, but that was from a while back, and I can’t find the link.
