Its a hornbill.
A single hornbill can cause a kind of havoc in your BH.
A BH owner sms his concerns and I told him not to harm the bird.
If it is single the hornbill bird must be a male.
He is out in the open to search for food since his spouse is locked inside a nest somewhere near his BH.
"Hornbills use an interesting nesting pattern. They build nests in holes, mostly natural cavities, hollow areas, in trees or rock crevices. However, unlike most other birds, all hornbills, except a few, seal the cavity entrance, leaving only a slit through which the female, and later her young, receive food from the male. The male brings mud to the female who use it, along with her saliva, to seal the opening. If mud is not available, the female will substitute her own feces, solid waste. Egg size and number, and incubation period, the time needed to sit and hatch the eggs, depends on female body size."
Try not to harm to the male bird.
If you kill this beautiful creature his spouse and baby locked somewhere in their nest will be dead.
