Off the top of my head, elephants, dolphins, and perhaps squid could pass such a test. I’m not sure about corvids. They are highly teachable and excellent at manipulating their environment, but are limited at tool use.
Corvids are significantly better at tool use than the other animals you mentioned.
They’re able to figure out that they can drop pebbles into a half-filled container of water to raise the water level, and doing it enough will raise the water high enough for them to be able to drink it. They also regularly use sticks to picl food out of tight spaces.
Overall, corvids tend to be as smart at 3-5 year olds
I wonder if a corvid could pass a comparable test (one more compatible)?
