Still hankering for the Emerald dove

I've been trying to capture better images of the Common Emerald Dove in the Bukit but have failed quite miserably so far.  It's a resident of the Bukit and has stunned many with its emerald colour, or green colour, as many walkers described it.  It's also seen very infrequently tough at Taman Rimba Kiara.
The best I've got recently was this when it flew down, for mere seconds, just metres away to fly off when it realised how close I was.  Sigh, another missed great photo opp for me!
