The DVD contains no different video beyond the three movies on youtube.
What I liked: better picture quality; an "extra" short feature on the now extinct Glaucous Macaw; the purchase supports the World Parrot trust efforts to help African Greys in their environment.

What I did not like: the "tag line:" "...a day in the life of Africa's grey parrot" implied I would see more of the activities of daily life in the natural environment.
But it was mostly about the life around one clearing, and the activities of those who capture the greys. So I did not get to see as much natural activity as I wanted to see.

If you see the 3 videos on youtube, you have seen this, just not as nice or convenient as on the DVD.
I'm still glad I made the purchase as the non-profit profit goes to a good cause.
