Seems to me you have what I call a gawu bird, but the real name is here. Sadly two are now near my house as well. Wife can shut them up with a slingshot.
Nature’s Alarm Clock A.k.a That F$%#ing Annoying Bird.
That is the Asian Koel. If you don’t live in Asia it won’t mean much to you. If you do then you will probably have heard these birds which are especially vocal during mating season. And right now it’s the time of year for Koh Chang’s horny Asian Koel population to make their voice heard.
It’s all very nice being woken up by the sound of bird calls when they are of the cute, tweeting variety. But, it’s an entirely different matter when you have a loud, repetitive ‘Koo-Ooooo’ at 4am in the morning. It wouldn’t be so bad if the range of these birds calls was limited to a small area, but it isn’t. You can hear them from a kilometer away. ( They are members of the Cuckoo family ) I’ve heard them in the city centre in Bangkok – above traffic noise.
So, you can imagine if you are in quiet surroundings and a lovesick male suddenly pipes up from a tree outside your room, or from a tree 100 metres away, you won’t be getting much sleep. Fortunately, the mating season is only a couple of months long – on Koh Chang from mid-December to February. "IamKohChang"
