A wild owl will feel threatened and undermined by a human in the event that they come excessively close and show certain forceful practices. The two most basic are puffing themselves out to seem greater and boisterously snapping their beaks.
Most owls, even the little ones, won't delay to attack on the off chance that it has smaller ones to secure.
In the event that it's a single owl, and you're simply strolling past, it will more often than not remain still wherever it is. Be that as it may, it will watch out for you.
Since owl parents consider looking into their homes in case of awful conduct and in addition a danger, remain well far from any homes in the trees and juvenile owlets on the ground. The parents will attack all of a sudden and you won't hear them coming.
