Crows can hold grudges for up to 17 years, scientists say

 Crows possess remarkable intelligence and can remember specific human faces. These birds hold grudges for many years after negative encounters. Experts have conducted experiments demonstrating this long-term memory. Attacks often occur during nesting season when parents defend their young. Building trust with crows can lead to positive and peaceful interactions. Crows possess remarkable intelligence and can remember specific human faces.
