Is non-verbal conceptualization in animals an unspoken language?

Animal behavior often involves identification/interaction with different objects, and other living things. Is this unspoken differentiation ability language?

Can an internal dialogue exist without a conventional language?

For instance, we see birds that choose some things to eat, and some to use as nesting materials. Despite the absence of words as we know them, can these actions be carried out without “precursor noun” information in their minds?

Likewise, if a bird is startled it takes flight, and thinks of the concept of the action of flight, a sort of “precursor verb”. I offer birds can differentiate between actions and nouns, naturally, and that this is a type of language.
