Why do magpies attack bumblebees?

Magpies attack bumblebees primarily due to their instinctual behavior as opportunistic feeders. These birds are attracted to the protein-rich contents of bumblebees, which serve as a food source, especially during the breeding season when they need extra nutrition for their chicks. Additionally, magpies may perceive bumblebees as easy targets due to their relatively slow flight and tendency to stay near flowers.
