Why do magpies attack each other?

Magpies often attack each other primarily due to territorial disputes, especially during the breeding season when they defend their nests from intruders. They may also engage in aggressive behavior to establish dominance or compete for resources such as food. Additionally, magpies are known to exhibit mobbing behavior, where they collectively attack a perceived threat, which can sometimes be directed at other magpies. This behavior is instinctual and helps maintain their social structure and reproductive success.
