The nest was already empty when I had a look yesterday. I had forgotten all about the nestlings after replacing the fallen nest onto a well hidden group of branches of the water apple tree.
Most probably all of them had flown away by now. Their mother had done a wonderful job raising them.
Two weeks ago I saw them gaping in anticipation of being fed. Their nest had fallen, most probably by a sudden gust of wind, by the drain.
Their mother was frantically flying and making noise in the mango tree nearby.
It looked like the mother returned to her chicks despite of my interference. What a wonderful mom!
They were the busy Philippines Glossy Starlings. Together with the yellow vented bulbuls, they inhabit our house compound. They share our trees - the mango, the water apple and the palm trees.
