Black Bulbul (紅嘴黑鵯) Day 1: laying

Since the bulbul (紅嘴黑鵯) determinded to have their nest on the narrow rim, I decided to make a birdhouse for them. It took me five hours to have that done and I planned to put it up there the next morning.
I was too late! In the morning of the next day, the bird was in the nest laying her egg!
