Greathornbills are one of the most common hornbill in india ,huge size and flight like a king called it's great hornbill. During my last southeast himalayan tour in bengal I visit jayanti hills near alipurduar westbengal. I found a huge number of different birds and mammals and macro elements. Great hornbill was one of them. Actually I was visit that place for this prticular bird. More or less 4-5 types of different hornbill was their. If anyone interested to visit their I will be their for you.
