Caiques exhibit a unique behavior known as 'surfing', where the bird will vigorously rub its face, wings and chest against any nearby soft item (e.g. carpets, towels, cushions, crumpled paper, curtains or human hair) whilst using its beak to pull itself along. During this, the bird will display jerky movements and may roll over several times. This behavior is thought to be a cleaning or bathing motion. In the wild, Caiques use wet leaves instead of carpets or towels. They are very happy at that moment.
