The first trial in which the rook Connelly is required to raise the water level by a varying amount. In this trial, seven stones are needed to raise the water level and worm to the reachable height. Connelly flies to the testing platform and investigates the apparatus before the stones are added. Connelly adds seven stones before successfully acquiring the worm. He then leaves the testing platform. See the paper by Bird and Emery in Current Biology 19(16): https://www.cell.com/current-biology/fulltext/S0960-9822%2809%2901455-9
