This is pretty cool:

Some pet parents already use mobile games and apps to help keep their parrots occupied. But these apps are designed for human fingers, not digit-less birds. Researchers wondered what changes they could implement to make mobile games more parrot-friendly, so they recruited 20 pet birds and their human caregivers to help them find out. The birds represented a variety of species, including macaws, grey parrots, cockatoos and parakeets.
