You might have noticed a crow cawing repeatedly at you sometimes. This is not a random event. A past experience with you likely influences the behavior of that crow. However, we cannot say that every crow remembers every single human face. Science confirms that some crows might not remember all faces, but they definitely remember the ones they find dangerous.
So, pay attention if a crow caws loudly in front of your house next time. Think if it recognizes you or if it is telling the other crows about you.
