Atleast your smart enough to change the subject line to fit what your talking about.

I myself still do not agree with them being clumped into one, no matter how many times you beat me over the head and force me to look at skulls. I see a difference in alot of things they do, how they act, how they look, grow, etc. in my eyes they will always be different. Just as different as prasinus to beccari.

I would never look or have a whitethroat and call it a blackthroat or vise versa. I would instead keep blackthroats as a sub species, a branch off the same tree but not the same branch. Thats the difference you seem to look at the tree and see many branches but yet go back to seeing the tree, and not each branch seperatly.

Now if you show me a whtiethroat of same size, color, shape, growth, etc. and another that only slightly differs such as the sienna whitethroat was it, now to me that is still very much a whitethroat.
