Basic knowledge about crows.

Introducing basic knowledge about the habits and breeding season of crows that inhabit Japan!

The crows of the genus Corvus found in Japan are two species: the Carrion Crow and the Hooded Crow, both of which are resident birds. Originally, they lived in forests and agricultural areas, but with the advancement of urbanization, they have expanded their distribution into urban areas, establishing an image as city birds. Their wingspan is 50 to 60 cm. They are omnivorous and their behavior of rummaging through garbage dumps has become a problem. The breeding season is from spring to summer, and they are monogamous, cooperating in raising their young. They build nests by weaving small branches in trees, but they also nest on utility poles, signs, and towers, skillfully using materials like wire and plastic that are readily available. During the nesting period, they become very territorial and may exhibit aggressive behavior towards humans or animals that approach carelessly. They are very intelligent birds, capable of discerning traps and have excellent memory. Those that have had experiences of being targeted by stones or guns will flee at the mere sight of someone picking up a stone or aiming an umbrella like a rifle.
