For much of the morning they were feeding on lerps and mostly hidden behind leaves. However, there is a pool of water in the fork of one of the trees and they all decided it was time for a drink at around the same time but there was always one who was claiming the watering hole for themself and chasing any other birds away (not always the same bird). There could be up to four or five birds loitering for their turn at the watering hole. Once they all had their fill it was all quiet at the fork of the tree but they then seemed energised and there was a lot of activity of them flying around from tree to tree, and much more visible among the leaves.
