A new scientific study has revealed that crows, long known for their intelligence, are capable of holding grudges against humans and other animals for years. The research highlights just how observant, socially aware, and emotionally complex these birds truly are.
Not Just Scavengers
Often dismissed as mere scavengers, crows are proving to be much more sophisticated. The study found that crows can remember faces, recognise individuals who pose a threat, and communicate this information to other crows within their community. This ability allows them to form social bonds — as well as long-lasting grudges — that influence their interactions over time.
Memory That Lasts Years
According to researchers, crows can retain negative experiences for several years, avoiding people or predators they perceive as dangerous. In some cases, they even pass on this knowledge to younger generations, effectively creating a “cultural memory” that persists within crow populations.
Why It Matters
These findings shed light on avian intelligence, challenging the notion that complex memory and social awareness are limited to mammals. Crows join the ranks of animals such as elephants and dolphins, which are known for their emotional depth and strong memory.
The study not only deepens scientific understanding of bird cognition but also raises questions about the ethical treatment of animals that display such advanced intelligence.
A Reminder From Nature
Crows’ ability to hold grudges serves as a reminder that the natural world is far more nuanced than often assumed. These black-feathered birds are not just part of the background of daily life — they are watchful, calculating, and capable of remembering how they have been treated for years.
