美國華盛頓州的雀鳥正受沙門氏菌－一種鳥類的致命疾病－所威脅。當地魚類及野生動物部呼籲市民收起後院的雀鳥餵食器至四月，讓雀鳥保持社交距離，避免因聚集而傳播疾病。

Salmonellosis is a fatal bird disease and is killing birds in Washington state. The Washington Department of Fish and Wildlife is asking people to take down their backyard bird feeders until April to avoid birds to gather and spread the disease.
