    #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?

    #5 Grackle vs Corvid - Motor inhibition on the detour task
    Grackles make the correct choice & detour to the side of a transparent tube to get food in 70.6% of the time, Eurasian jays 58.3%, & Western scrub jays 76.7%
    Score 3:5 (tie bc grackles are at high end of corvid range)

      Are the more behaviorally flexible great-tailed grackles also better at inhibition? See details at http://corinalogan.com/Preregistrations/g_inhibition.htmlT...

    EXTRA
    We found that grackles use self control using a go no-go test on a touchscreen computer. Yep, grackles can use computers! I don’t know of an experiment in corvids that is comparable to our self control experiment and I also don’t know of corvid tests that use computers

      Using touchscreen equipped operant chambers to study animal cognition. Benefits, limitations, and advice
      Operant chambers are small enclosures used to test animal behavior and cognition. While traditionally reliant on simple technologies for presenting stimuli (e.g., lights and sounds) and recording responses made to basic manipulanda (e.g., levers and buttons), an increasing number of researchers are beginning to use Touchscreen-equipped Operant Chambers (TOCs). These TOCs have obvious advantages, namely by allowing researchers to present a near infinite number of visual stimuli as well as increased flexibility in the types of responses that can be made and recorded. We trained wild-caught adult and juvenile great-tailed grackles (Quiscalus mexicanus) to complete experiments using a TOC. We learned much from these efforts, and outline the advantages and disadvantages of our protocols. Our training data are summarized to quantify the variables that might influence participation and success, and we discuss important modifications to facilitate animal engagement and participation in various tasks. Finally, we provide a “training guide” for creating experiments using PsychoPy, a free and open-source software that was incredibly useful during these endeavors. This article, therefore, should serve as a resource to those interested in switching to or maintaining a TOC, or who similarly wish to use a TOC to test the cognitive abilities of non-model species or wild-caught individuals.

    Hi @ct_bergstrom and @cobalt Thanks for inspiring a thread on grackle vs crow cognition! It turns out that the grackles are quite the contenders - sometimes their performance is the same as crows, sometimes worse, and sometimes better. Here are the details…

    #1 Grackle vs Crow -Aesops Fable water tube tests
    - Heavy vs light: most grackles & all crows preferred to drop functional heavy objects. Score 1:1
    - Wide vs narrow: no grackles had a tube preference, while most crows preferred to drop objects into the functional wide tube. Score: 1:2

      Behavioral flexibility and problem solving in an invasive bird
      Behavioral flexibility is considered an important trait for adapting to environmental change, but it is unclear what it is, how it works, and whether it is a problem solving ability. I investigated behavioral flexibility and problem solving experimentally in great-tailed grackles, an invasive bird species and thus a likely candidate for possessing behavioral flexibility. Grackles demonstrated behavioral flexibility in two contexts, the Aesop’s Fable paradigm and a color association test. Contrary to predictions, behavioral flexibility did not correlate across contexts. Four out of 6 grackles exhibited efficient problem solving abilities, but problem solving efficiency did not appear to be directly linked with behavioral flexibility. Problem solving speed also did not significantly correlate with reversal learning scores, indicating that faster learners were not the most flexible. These results reveal how little we know about behavioral flexibility, and provide an immense opportunity for future research to explore how individuals and species can use behavior to react to changing environments.

      Modifications to the Aesop's Fable Paradigm Change New Caledonian Crow Performances
      While humans are able to understand much about causality, it is unclear to what extent non-human animals can do the same. The Aesop's Fable paradigm requires an animal to drop stones into a water-filled tube to bring a floating food reward within reach. Rook, Eurasian jay, and New Caledonian crow performances are similar to those of children under seven years of age when solving this task. However, we know very little about the cognition underpinning these birds' performances. Here, we address several limitations of previous Aesop's Fable studies to gain insight into the causal cognition of New Caledonian crows. Our results provide the first evidence that any non-human animal can solve the U-tube task and can discriminate between water-filled tubes of different volumes. However, our results do not provide support for the hypothesis that these crows can infer the presence of a hidden causal mechanism. They also call into question previous object-discrimination performances. The methodologies outlined here should allow for more powerful comparisons between humans and other animal species and thus help us to determine which aspects of causal cognition are distinct to humans.

    #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)

    #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
