The Mocking Bird in G.\lli.\ 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.
