We were going down the Brunei River on an eco-tour when we spotted huge flocks of white birds skimming across the water. They leave each morning and return to roost at night.
The Brunei economy is driven by oil, which they have in abundance offshore. Here is a close-up of one of the large offshore oil rigs. You would not want to hit one!
Water villages often have electricity, running water, telephones and all the other comforts of land. Only about a third has sewage lines; the rest simply discharge into the river. This seems to be environmentally benign; the problem is they also throw their non-biodegradable garbage into the river.
This shot, taken near the Royal Brunei yacht Club shows an interesting contrast between the traditional water village lifestyle and modern homes on the hilltop above.
