The spoon-billed sandpiper, one of the world‟s most critically  endangered bird species, has fewer than 150 pairs globally. In each spring  and autumn, around 100 pairs appear in the Xiaoyangkou area, earning it  the title of “Hometown of the Spoon-billed Sandpiper”. The spoon-billed sandpiper primarily feeds on insects, insect larvae,  crustaceans, and other small invertebrates. They are often seen foraging  alone in shallow waters along the shore or in soft muddy areas. When  walking, they keep their heads lowered and continuously probe their beaks  into the water or mud, which allows them to search for food while moving.
