G. PHILADELPHIA: MOURNING WARBLER. 167 



land for every collector there to be glad to make its 

 personal acquaintance. It is only known to occur 

 there as a migrant in spring and fall, chiefly May 

 and September; and it is rather a late arrival, in 

 the rear of most of the Warblers. The case is dif- 

 ferent in the Canadian Fauna, where the bird breeds, 

 and quite plentifully in some localities in Vermont, 

 New Hampshire, and Maine. Mr. Maynard, for 

 instance, found it common at Umbagog in June. 

 Still it is locally distributed even in its native Fauna ; 

 Mr. N. C. Browne mentions the taking of speci- 

 mens at Portland as an event of unusual occurrence. 

 I should not 'be surprised to hear of its occasional 

 nesting in Massachusetts. The general habits of the 

 bird are those of the Maryland Yellow-throat ; but it 

 does not hug the shrubbery so closely, at least in 

 the mating season, when the male may be observed 

 in the tops of the trees in mixed woodland, where the 

 undergrowth is convenient for hiding, singing a bright 

 hearty song. At such times the female is very secre- 

 tive, being seldom observed. The nest and eggs, of 

 which little is yet known, are said to resemble closely 

 those of the Maryland Yellow-throat. The Mourning 

 Warbler, like a few other species not less characteristic 

 of the Eastern Province of North America, is neverthe- 

 less not so common a bird in any of the Atlantic States 

 as in the interior of the country. It is one of the most 

 abundant Warblers in summer in Minnesota and Da- 

 kota, along the Red River of the North, where the 

 great woods are vocal with its refrain in June. This 

 consists of five or six notes, simply warbled, with a 

 rising inflection of the voice on the first three, and then 

 a cadence.
