MOURNING WARBLER 



Mississippi. It is a rare migrant in Louisiana, but is fairly common in 

 migration in Texas, and has been noted in eastern Kansas (Topeka, 

 Neosho Falls), eastern Nebraska (Omaha, Neligh), and eastern North 

 Dakota (Cando). 



Its distribution in the United States is, therefore, fan-shaped. 

 Touching the Gulf of Mexico along the coast of Louisiana and Texas, 

 a distance of six hundred miles, the lines of migration extend north to 

 Manitoba and northeast along the west side of the Alleghenies to New 

 Brunswick, Nova Scotia and the Magdalen Islands. The east and 

 west extension of the breeding ground is nearly two thousand miles. 



Winter Range. — Nicaragua to Ecuador. 



Spring Migration. — The Mourning Warbler is one of the latest 

 of the family to arrive from its winter home in Central and South 

 America. It probably reaches the United States late in April or the 

 first week in May.
