White-breasted Waterhen

This video is the result of weeks of waiting and observing one single spot near a paddy field in Kurunegala. On the route I've chosen to walk between my workplace and home is a big shallow hole close to a rice field that gets filled by the rain in the rainy season. That's where I saw an opportunity to have a go at a  White-breasted Waterhen(Amaurornis phoenicurus), locally known as Korawakka . But it was no easy task. These birds will remain in the open as long as I leave them alone, but dash in to hiding if I so much as  just look at them. But today in the morning I got lucky with one. Having made a couple of videos, I moved on for work. Although it was pretty hot and humid when m,y work was over, I decided to walk home with out taking a bus, hoping I'd be lucky again. And this time there were two of them. I couldn't get the two together in the video though. Like some scientific information of this bird?
