Cockatoos teach each other tool-making tricks

Goffin cockatoos have shown an impressive ability to learn from one another how to use and even how to make tools.
A team of researchers has discovered that the birds emulate tool-making tricks when they are demonstrated to them by another bird.
In this clip, the "innovator" bird, named Figaro, demonstrates to another caged bird how to make and use a food retrieving stick.
In the second scene, the bird that has seen the demonstration emulates Figaro's skills.
