The Mocking Bird in Gallia County. 
Four years ago, the first Mocking Bird, Mimus polyglottus, 
was seen at Rio Grande. Its^nest was not found. This year at 
least five nests were found within the village and the birds seem 
quite numerous through the country. Heavy winds overturned 
three nests and the young ones perished in spite of human efforts 
to replace and strengthen the nests.
