Habits. According to Wickham this is a Bulbul of high elevations during the breeding season, when it is found from 6,000 feet upwards. In the non-breeding season it comes down to lower elevations between 8,000 and 4,000 feet, going about in small flocks. Their note is harsh but quite typical of the family.
