Golden Bellied Flyeater - heard but not seen

Go for a morning walk (yeah ... I know it is tough to let of that soft pillow... but do try!) and you will invariably hear a rather happy sounding bird whistling to itself. I have heard this bird for ages, and now I finally know who it is.
The recordings and video on the net do not exactly coincide with what I have been hearing daily (perhaps different birds, different tunes?!) , but this gay sounding bird is definitely the Golden bellied flyeater. I sure hope to see you some day... but till then... in a sad attempt to imitate James Bond, the golden bellied flyeater remains ...

...Heard, not seen

Meanwhile, I will keep myself happy looking at this photo by Jun Osano (Maia bird calls it one of the 10 most common urban birds - she means in Manila, of course)
