A crow's math skills include geometry
Briefly

A recent study reveals that crows possess the ability to identify geometric regularity, a skill previously thought exclusive to humans. Conducted by cognitive neurobiologist Andreas Nieder, this research demonstrates that crows can distinguish between four-sided shapes based on geometric properties. Using computer games, crows displayed remarkable cognitive skills, suggesting they may have an inherent understanding of geometry. Nieder notes this could just be the beginning of exploring geometric intuition in various species beyond humans, hinting at a broader cognitive capability in animals.
Claiming that it is specific to us humans, that only humans can detect geometric regularity, is now falsified, because we have at least the crow.
I would never dare to say that this is the only species; it's just now opening this field of investigation.
For instance, five moons and one flower...When the crows pecked on the flower shape, they got a snack.
The crows' counting ability rivals that of toddlers. These crows are very tame, so they like to work with us.
