Crow Puzzle Introduction

Using my dog's puzzle. I've been slowly introducing the crows to cups and other things that they have to move to get the treat underneath. Of course even the blue cones here were never a challenge for them until now, as they simply had to poke or tug on them to make them tip over. Now that I'm setting them inside the puzzle, the crows have to actually lift the cones out. Whisper here went for the easy pieces first before attempting the more challenging part, which he gets visibly frustrated over and even walks away. I know he would have gotten it eventually, but it was my own patience that ran out first so I made it easier for him.

The puzzle gets more complicated, with sliders and other holes that force them to solve it in a kind of order. I have yet to use these but it won't be long before they're more comfortable with this strange new object to be ready for that.
