7 cultured animals that share knowledge: Apes
They've found culture and learning in all the mammals they've studied. Intelligence is everywhere.
You left out two of the most cultured and smart birds on the planet! Crows and Ravens are highly sociable, intelligent and very cultured birds. They usually mate for life, both parents raise their young, use tools and have whole socities of birds (called murders). They can adapt to almost any situation, food and weather.They have their own language. I always thought them as pests until I rescued a baby that couldn't perch. He fell out of a tree upon hatching and had a gimpy leg) I had him for 14
years and was one of my favorite pets. They are perhaps one of the more sociable animals on the planet and don't get enough credit!
