As a linguist, article like this also annoy me by the claims that "X [whales, dolphins, parrots, crows...] uses language." We have known since 1957 that there is a hierarchy of "grammars", with finite state "languages" being near the bottom, and transformational grammars at the top. Human languages are certainly at a minimum at the context free phrase structure grammar level. My point is that by using the word "language" loosely, almost anything (DNA codons, for example) can be considered to be a language. But few if any other animals can get past the finite state level--and perhaps none gets even that far.
And an article or book that uses the word "communicate" is even more annoying, since "communicate" seems to mean virtually anything.
