Knowledge itself is really not much unless it's applied. Corvids apply their knowledge/intelligence. I'm sure some is innate and some is learned. My children do the same. My youngest son was brainy from day one. There is nothing he cannot solve given the time. My older son is very intelligent as well, but his mind is different. He's more physical in nature and lends his mind to physical pursuits like how to drive a ball farther, stance, wrestling moves, etc. They learn and apply knowledge differently. I'm sure there are corvids for whom cracking nuts themselves is great fun/skill shown, whereas there are some who will use a passing car tire to do the work for them. Some people enjoy working on their own cars while others see it as useless and infuriating. Both types can do the work, one sees it better as simply paying for it. I appeal to Robert Heinlein here. Specialization is for insects. People should be able to do many things well. It just makes you stronger. I remember once in the Corps when we were deploying. A young Marine was laying out all of his gear for inspection, required and permissible personal stuff he believed would aid him. The Gunny walked over and said, "Dude, you are going to kill yourself humping all of this extra crap. You don't need any of it. The more you know, the less you have to carry."
