Black-and-white Munia (Lonchura bicolor)
Funny that I should encounter these couple of B&W Munias as Francis Yap aka "Houdini" / "Escapee King" had just shot and posted these escapee birds from Africa just the previous day... seems whenever he finds a new escapee species they then pop up immediately at many other places !!! :)
Postnote: Re-processed this pic cos my earlier WB and Post Processing (PP) was off and the black had a slight lilac tinge.. hope this re-processed pic is now more correct and accurate to the bird's actual colours..
