Hello, everyone! With the arrival of spring, one of the sights that becomes more common in cities across Japan is the procession of spot-billed ducks and their ducklings. Led by the mother duck, the adorable sight of the ducklings walking in a line is truly endearing! But why do spot-billed ducks “move” in the spring? Let’s delve into this mystery.
The spot-billed duck is a species of duck that lives in various parts of Asia, including Japan, and unlike other migratory birds, it resides in Japan throughout the year. Males measure 60cm in length, and females 50cm. Both male and female spot-billed ducks are blackish-brown, with white faces marked by black lines, black bills with yellow tips, and orange legs.
Being omnivorous, the spot-billed duck feeds on small fish, insects, and aquatic plants, which leads us to one of the reasons for their “move”! Spring marks the breeding season for these ducks. Females make nests in grassy or bamboo areas near water bodies and lay their eggs. Once the ducklings are capable of walking, the parent leads them to safer locations abundant in food. This guidance is facilitated by a phenomenon known as “imprinting,” where the ducklings firmly recognize their parent and follow closely. Fascinating, isn’t it?
This “move” not only ensures the ducklings can find food but also serves as a strategy to protect them from predators! Hence, the ducks may move several times until the ducklings become independent, changing locations to stay safe.
However, this journey is not without its dangers. Crossing roads requires caution to avoid cars, and predators such as crows and cats pose threats. While there are times humans can offer assistance, the spot-billed duck family primarily relies on their own strength to overcome challenges.
The spot-billed duck’s migration can sometimes necessitate police intervention, highlighting the wisdom and courage needed to survive. The next time you see a procession of spot-billed ducks, consider supporting their grand adventure. Their journey is not just adorable but a story of survival wisdom and courage. Until next time, see you again!
