Also when lid got stuck in the snow (at the end of the second good slide) crow could peck it for as long as he liked. If he wanted to get something out of the lid he would continue to do it not fly again to the top.

I think the pecking only purpose is to make the lid slide down. Apart from that pecking is the same for him as the touch is for us. We tend to move our hands and fingers a lot to improve our sense of touch when we operate an object.

He flies to the top because he needs something hard under the lid, not the soft snow.

After two thirds of the video the crow figures out that by having one leg on the "ground" the jar won't slide down when he picks and pulls at it, then spending the last third of the video in this position.
