nankeen or rufous?

["Tom and Mandy Wilson" <>]

Laurie is right - to our modern eyes, the night heron is more obviously 
rufous above than nankeen below, but as to obscurity, I strongly suspect 
that when the "nankeen" birds were first described, nankeen was not an 
obscure term as it was a material in common use in the 18th & 19th 
centuries.  Obviously, time have moved on and nankeen is obscure to us. 
(Using the MD Definition - the bird should be "chestnut-brown night heron"!)
(Perhaps I didn't understand the other question - aren't both male and 
female rufous whistlers rufous, the other dominant colour being grey, and 
there's already a grey whistler?)
