The translators were predominantly literary types, such as poets, without much input from scientific types who might have recommended some wording having more physical connotations, or linguistic scholars who could point out the details of scientific terminology.  For example, "owph" is translated as "fowl" rather than the linguistically and scientifically correct "winged creature."
