Observing a bird

Yesterday afternoon, I was so excited to observe the behavior of a bird. I was aiming at a distance of about 5 or 6 meters. It was perched on a tree branch falling leaves. It is Sooty-headed bulbul, in Sumatra, the bird known as: kutilang, and Acehnese called it: brujuk gapeuh. At the time of our childhood, we often sing a song. Here's roughly that lyric:

In the treetops of Jeumpa
bulbuls reads
whistling all day
with not bored
nodded while singing

While leaping
its beak always open
shook its head
overlooking the blue sky
sign, it loves to sing
