In the skies above, crows are quietly running one of the most complex social networks in the animal kingdom. These birds don’t just recognize human faces — they remember them, hold grudges, and pass those grudges down through generations. A famous experiment from the University of Washington revealed just how deep this goes: researchers wearing specific masks captured crows, then released them. Years later, crows still attacked anyone wearing those masks. But more astonishingly, young crows who weren’t even born during the original event joined the mob. Why? Because they learned from their parents. Crows teach. They strategize. They remember. Mess with one, and you might earn the wrath of an entire family tree.
