These Australian Cockatoos Learned to Operate Drinking Fountains With Their Feet to Quench Their Thirst

  • Researchers led by Barbara Klump observed sulfur-crested cockatoos in Western Sydney operating public drinking fountains in a study published in Biology Letters in 2025.
  • The behavior, studied over 44 days with 525 recorded attempts, emerged from the birds' adaptation to urban environments and required coordinated actions to activate the fountains.
  • The cockatoos used their beaks and feet to twist handles, waiting in lines and taking turns, demonstrating varying skill levels and social coordination at the fountain.
  • The birds were successful in activating the fountain in 41% to 46% of attempts, with co-author Lucy Aplin noting that the task involves a highly intricate sequence of precise motor skills rather than sheer strength.
  • This behavior suggests urban-adapted local tradition among cockatoos and raises considerations for species habitat needs and urban biodiversity as these birds prefer cleaner fountain water over natural sources.
