Not disputing this, but hanging around and waiting isn't the same as performing tasks for the same.

Again cats are harder to train than dogs, and that's with treat enticement too. Yet they will certainly make a face when given lesser food.

Also, keep an eye out for one crow watching for you to appear with treats. Once you do, he'll call the rest of the tribe.

I noticed a ypunger crow doing this. Unclear if it was assigned the task as a junior, or did so for street cred.

Adults were busy at this time of year showing juveniles how to find food and such.
