At this time of year, the tide level is low in the Sea of ​​Japan, so white wagtails are searching for food on the rocks that are exposed to the sea surface. Yesterday's tide level was a maximum of 17cm and a minimum of -5cm, with a width of only about 22cm. It's surprising how small it is compared to the Pacific Ocean.
今の時期の日本海は潮位が低いのでハクセキレイが海面に出た岩の上でエサ探ししています。昨日の潮位は最高17cm最低-5cmで幅がおよそ22cmしかないです。太平洋と比べたら小さくてビックリですよね。
