MOURNING WARBLER 



The Mourning Warbler is one of the latest of the family to reach the 

 United States from its winter home in Central and South America. It is 

 not known in the Gulf States at ocean level east of Louisiana, nor in 

 Georgia and South Carolina outside of the mountains, and there are only a 

 few records south of Pennsylvania. It probably reaches the United States 

 late in April or the first week in May.
