The spot-billed ducks were scraping algae on the concrete and filtering only the algae in their mouths. As they did so, water was pouring out of both sides of its bill. Birds of the duck family have a clever mechanism. You can see the mechanism in the swan. Visit the next site. ⇒ http://wakatsuk.blog68.fc2.com/blog-entry-94.html
In general, bird chicks stay in the nest and are fed by their parents. Chicken chicks and ducklings, on the other hand, forage for their own food shortly after they hatch. These parent birds do not feed their chicks. In the case of the spot-billed duck, there are 12 chicks at a time, and it would be impossible for the mother to feed them.
The author encountered the following scene on a day of heavy rain. Due to heavy rain, the Ooyagi River was risen. The spot-billed chicks were hungry because they had less food to feed. There was a mulberry tree by their side, and their mom was full, eating mulberries, but the chicks were able to pick up a mulberry but could not eat it. A chick did not eat after picking the fruit with the beak and poking it smaller. Mom repeatedly came near the mulberry tree. Probably because a lot of mulberry fell. We are confirmed that there is an exception, although the spot-billed chicks are said to eat the same foods as their parents. Taken on June 6, 2019.
