Explanation:

The Hornbill Festival is a celebration held every year from 1 to 10 December, in Nagaland, Northeast India. It is also called the 'Festival of Festivals'.
The state of Nagaland is home to several tribes, which have their own distinct festivals. More than 60% of the population of Nagaland depends on agriculture and therefore most of their festivals revolve around agriculture. The Nagas consider their festivals sacred, so participation in these festivals is essential. To encourage inter-tribal interaction and to promote cultural heritage of Nagaland, the Government of Nagaland organizes the Hornbill Festival every year in the first week of December. The first festival was held in 2000. The festival is named after the Indian hornbill, the large and colourful forest bird which is displayed in the folklore of most of the state's tribes.
