The Open­bill’s Pref­er­ence for Snails

China Scenic - - Wildlife -

The diet of Asian openbills is highly spec­i­fied—they have a strong pref­er­ence for snails, in­clud­ing the in­va­sive chan­neled ap­ple snail. Based on re­search data, a 15-day old nestling can eat 143 grams of snails in mere 24 hours, al­most equal­ing its own body weight. Asian openbills are sen­si­tive to snails and clams hid­ing in the mud. Wad­ing in the marshes and farm­lands, they search the muddy land with their odd-look­ing bills, just like a farmer plow­ing the fields.
