This little Warbler is usually rare in this State. The specimens in the Collection were 

 shot, May 20, in this neighborhood. It has been observed in Massachusetts, which appears 

 to be its highest northern range along the Atlantic coast. Audubon has noticed them in 

 Louisiana, but the history of its migration and of its incubation is yet unknown.
