GeoCxRAphicae Distribution — Migration Range. — Kast- 

 ern North America, occasionally straggling westward, even to the 

 Pacific coast. 



Breeding Range. — In summer essentially confined to the 

 Canadian fauna, and, though breeding southward in the mountains 

 in straggling numbers, its chief breeding grounds are from the north- 

 ern United States northeastward. 



Winter Range. — Stragglers winter from Cape Elizabeth, 

 Maine, southward along the coast, but the species chiefly winters 

 from southern New England and the Ohio valley southward to the 

 West Indies and through Mexico to Panama. 



At the approach of warm weather the Myrtle Warblers enter 

 the State from their southern winter homes. Though a few indi- 

 viduals have been recorded as wintering near Portland at Cape Eliz- 

 abeth (Cf. Brownson, Journal Me. Orn. Soc, March, 1905, pp. 

 27-28), this may be attributed to peculiar local conditions. The 

 first individuals usually arrive in southern Maine about April 15th 

 to April 22nd, and the usual time of appearance of the species at 

 Bangor is about April 22nd to April 30th. The first individuals 

 reach extreme northern Maine about May ist. Common throughout 

 the State during the migration, the individuals gradually diminish 

 in numbers until by the tenth of May practically none are to be 

 found in southern Maine, and, leaving a fair proportion of their 

 numbers to nest in northern, eastern and western Maine within 

 Canadian faunal limits, the tide of migration passes beyond our 

 boundary. 



The scattered flocks pass on, leaving here and there a pair of 

 mated birds, in many instances individuals being found frequenting 

 the very same localities from year to year under conditions which
