> You're right about taxonomic descriptions. It's rare that we see much discussion of behavior in them because taxonomists > rarely have anything but preserved specimens . and is very difficult, even today, to preserve behaviour in a museum. Many botanical taxonomist don't discuss the colors of flowers because colors fade out in preserved specimens. But I can recall just now that Helmutt Sick, writing on Parrots, was discussing that the Queen of Bavaria's (Aratinga guarouba) should be returned to the genus Guaruba because his voice was very different from the other members of Aratinga. And that Pionus maximiliani could be easily recognised at distance from the other Pionus by its charcteristic wing-beats.
