It seems that there are certain critters that are deemed worthy of emulation (Beatles (yes, I know how to spell the critter), Eagles, etc.) But what about other such bugs, birds, or such? Green Night Herons are really intelligent-seeming birds, but as far as I know, no one has grabbed that for a name. Funnel-web spiders are among the most fearsome of venomous arachnids, Stoats are pretty ferocious little predators, Fisher Cats too, but much larger. What makes an Eagle an appropriate name-source, but a Nighthawk not so much? (Actually, that one, with all the associations regarding the eagle, I sort of get, but...) Whippoorwills?
