I usually see this kind of birds flying around at around 5 to 7 a.m. in the morning. Then, they would disappear during noon and appear again at around 1 or 2 p.m. in the afternoon.
All seen during during jungle trek portion of Green Discovery kayaking and trekking tour. The tour runs through a section of protected primary rainforest still used by villagers with some areas cultivated for growing rice. Weather was humid and sunny during the day with some rain at night. Seen during night walk through rice patties and other areas around village.
