   #3 Grackle vs Crow - String pulling
   Only 1 grackle spontaneously pulled a string, while many crows spontaneously pulled strings (though, at the individual level, crows did not attend to the functional differences among the strings).
   Score 1:4

   However, in a later experiment using a puzzlebox, most grackles pulled a string, which was one of four methods of accessing the food (https://doi.org/10.24072/pcjournal.284)
