   #2 Grackle vs Crow - Stick tool use
   Grackles didn't spontaneously use a stick to obtain food from a hole, while crows did.
   Score 1:3

   This isn't surprising bc New Caledonian crows make & use tools in the wild, while grackles do not. However, after this article came out, someone in Texas said they see grackles using sticks to pull dead bugs out from the base of the car’s windshield. Mb pop diffs in grackle tool use?

   #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)
