YELLOW-GREEN VIREO 



This Vireo has scant claim to a place in the fauna of the United States. It 

 occurs regularly in northern Mexico not far south of the United States boundary, 

 and extends thence through Central America to northern South America. 



Wanderers have been taken three times in the United States; at Fort Brown, 

 Texas, August 23, 1877; Riverside, California, September 29, 1887; Godbout, 

 Quebec, May 13, 1883. 



YELLOW-THROATED VIREO 



This Vireo winters south of the United States, and in spring those individuals 

 that are to nest on the Atlantic slope make the long flight across the Gulf of 

 Mexico to northern Florida and the Gulf States, avoiding the shorter and easier 

 flights by way of Cuba and southern Florida.
