Sulphur Crested Cockatoo's biting off leaves or small branchlets and then pulling leaves through their beak, it what looks like a licking of the aphid and their secretions. Feeding occurs over many days, by up to ten Cockatoos with much pruning of leaves. Crimson Rosella also observed doing the same but not as regularly
Also saw today 4 June 2025, Eastern Rosellas using similar method of feeding on aphids and their excrement and also Noisy Miners using different feeding technique of picking off individual aphids.
