🐦⬛It's not cruelty, it's survival🐦⬛
The bird world during springtime is surprisingly intense. Many species become territorial and aggressive when raising young. In our cities the crow is one of the larger, louder birds we notice this behaviour in.
Every Spring people start noticing crows becoming loud, aggressive, and protective toward other birds - and sometimes even toward people. Their behaviour can look cruel and unprovoked, but what we are seeing is the parenting and survival instincts of crows in action.
During breeding season crows are defending nests, eggs and their vulnerable young chicks. Many birds pose a threat to those nests and crows respond by chasing intruders away, mobbing predators and fiercely protecting their territory.
People are often especially upset when they see crows raiding other birds’ nests, taking eggs and chicks. As harsh as it seems to us, this is natural behaviour. Crows are opportunistic omnivores, which means they eat whatever food is available - insects, carrion, seeds, scraps, eggs, and sometimes the nestlings of other birds. During breeding season, crows need huge amounts of energy and protein to raise their own young.
Crows do not kill for enjoyment. In the same way that hawks hunt, foxes raid nests, and gulls steal chicks, crows do what they need to do to survive and care for their young.
This is no different to behaviour that can be seen in many David Attenborough documentaries where animals are observed in the wild - although it can be harsh to witness, they are natural behaviours for these wild urban birds.
At the same time, while many people believe Nature should never be interfered with, compassion is also natural. Humans are part of Nature too, and the instinct to help an injured, vulnerable, or suffering animal is not wrong. There are times when intervention can genuinely save a life - whether that means moving a bird out of danger, contacting a wildlife rescue, or helping an exhausted animal reach safety.
Crows are incredibly intelligent and social birds. They communicate with each other, remember threats, and work together to keep their young safe.
So if you see crows acting aggressively at this time of year, please remember, they are being protective parents doing everything they can to help their family survive.
