   #4 Grackle vs Corvid - Flexibility measured as reversal learning
   Reversal learning speeds (average # of trials):
   Great-tailed grackles = 74
   Pinyon jays = 155
   Clark’s nutcrackers = 143
   California scrub jays = 191
   Score 2:4

   I compared the grackle data with studies on other species who used similar methods and passing criteria. See 4th paragraph of the Discussion in this grackle article for all references: https://dx.doi.org/10.24072/pcjournal.320

     #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)
