Each call says something about the deepest molecular biology of the animal, as well as how and with what on the earth the organism has interacted throughout its individual life. From the textures and fibres in the birds' throats to the colour of their plumage, from their food preferences to their mating rituals, from their hunting and social interaction to their experiences of loss, each call somehow encapsulates those realities and all unnamed others which is that bird. If only this kind of information were not highly coupled and so multidimensional, we might be able to tease out more of these life experiences from the individual bird. Yet, it remains nearly impossible, like so much in life, to resolve such issues, if only at a probability, thus shrouding the whole reality in the mystery. Thus, our power is left dry and our desire to know is essentially stifled by a beautiful bird. We can only know in part.
