As a migrant this species occurs in southwestern Maine

 its occurrence near Portland as the second week of May for a

 while the average date of arrival at Bangor is nearer May 

 fifteenth. Occasional individuals remain near Bangor excep-

 many miles from being the center of the State, the Olive-backed

 numbers, but occurring in nearly equal numbers with the
