We have this small pair of birds nesting 3 meters from our gas stove. Very interesting to follow so closely.
The closest I can come to an identification is some type of Bulbul.
The male and female looks the same.
The only "singing" I have heard sounded like drrrdrrrdrrrdrrr.
Bulbuls can be tough to identify - especially the 'drab' brown ones! But you have a nice close, clear image here that makes it easier. Those subtle streaks on the cheek give it away as you have suggested - it's definitely Streak-eared Bulbul.
