Have you ever been to Izunuma lake in Miyagi? It is the lake where swan and ostrich fly over once a year.  Recently, we as a family went there and the scenery of bird crowding was excellent. This is officially registered as the migrant bird place. Local people feed bread and used tea leaves. Around mid-February, those birds fly away from Izunuma lake. Maybe because of global warming, fly away time is earlier than usual. From last broadcast, birds are got twisted by fishing needle and the string. I felt fishing people should keep the manner to protect the nature.
