Yeah corvids have (at the very least) simple languages and dialects, and are known to pass knowledge of good vs bad humans across generations. My grandpa nursed a crow back to health when he was in his 20s, and decades later sitting on the same bench in his 80s, crows would still regularly land on his shoulder. No one else's. I assumed they just like looked at a person and made primitive happy or angry sounds, but apparently it's deeper than that

Elephants are maybe even cooler: vocalization's only a small part of their communication, and they mainly use combination of seismic vibrations from their feet & ultra-specific body language. Their amount of variation between body/trunk/ear posture is way more subtle, complicated, and intentional than anything humans do for body language. It may even be something like a sign language, with its own grammar and syntax. Their feet are also incredibly sensitive, picking up vibrations invisible to everyone else: so they make extremely precise vibration-creating movements to send specific, patterned messages to each other via the ground. They'll also do this with a much louder rumbling when they need to send info to a friend several miles away
