觀察細節
This afternoon I got to observe a pair of these common birds, as they sat on the tamarind tree branch, outside our house. Both birds were perched next to one another, preening themselves busily. In fact in the thirty minutes that I watched the pair, they were preening for over 90% of the time. They kept moving and shifting their positions most of the time. In the course of their movement, they kept crossing each other. They were seen "billing" and perhaps the male bird was feeding the female some regurgitated food? On three occasions, they were seen copulating, the female sitting in a submissive posture, awaiting the male bird to mount. Once it was brief and perhaps no copulation actually took place. On the other two occasions there was cloaccal contact and the male tried to balance himself by fluttering its wings. Twice they briefly flew out with loud flapping sounds only to return within a couple of minutes and shifted to a different branch. The birds were quite tolerant of my presence as I observed and photographed them.
