Yes Vik, these birds are tremendously difficult to stalk. This rather poor shot was taken from a fair distance and then I set about trying to get closer. We played "now you see me now you don't" games for quite a while including a lengthy Mexican stand-off where both I and the bird (behind vegetation) stood stock still looking at each other for ages. However, I blinked first and he was gone.
It's obvious the bird's wariness was more than a match for my sneakiness as this is still my only shot. Ah well some other time.
By the way Vik, love the rainbow effect in your shot.
