Found the sollution. Tips below (spoilers):
1 - Find the full map picture (book page + cut part).
2 - The parrot gives the full path to navigate the map (also, the map has north and south inverted - see compass on the side). Draw the full path on the map.
3 - The number in each vessel is their volume (how much water you can put inside).
4 - Follow the path on the map to make instructions. Each pair means to put the volume of 1st into the 2nd. Water icon means to totaly fill the vessel. Write down the amount of water inside each vessel in the end.
5 - Inside the well, click the amount of water inside each vessel, in the order that appears on the wall.
