A sulphur-crested cockatoo named Snowball (hatched in 1996) became well-known in 2008 for what?

Question

Canfranc, in the Pyrenees on the border between Spain and France, became especially well-known for activities during World War II. What was it?

Answer 1

Dancing
Research in 2008 and follow-up research in 2019 concluded that it was genuine dance, a spontaneous and untrained response to the beat where the dancer matches motion to music. The 2019 research then identified creative and new moves, and further behaviour which they assessed as definitely dance. Genuine dance is extremely rare in the animal world, being almost exclusively seen in humans.
