Kuala Selangor - Great Egret

its been a while since I pay attention to egret. However today apart from this individual there is another one with confusing marking. I'm rather convince it is a great but the whole leg is PINKISH. Most great are all black. I was wandering why. If anyone have any idea do let me know.

Here is a picture of a Great Egret(not the weird individual mention)
