It's the oriental pied hornbills.
I was that Chek Jawa with my photography friends at about 9am plus.
The hornbills were very active today as compared to my other visits to Chek Jawa.
We heard them as we were walking in to Chek Jawa.
Accompanying the sound of the hornbills was a woodpecker pecking at a tree branch right above our shooting location.
I didn't get a picture of it thought. It was covered by some tree ferns.
I saw them flying around at the start of the boardwalk and again at the coconut tree at House No. 1.
Later in the afternoon, I saw another pair at the butterfly hill, not far from the HSBC volunteer's house.

I think that hornbills are great birds.
