398 NOTES ON THE 



Tbey have a simple note which is almost constantly repeated 

 in a subdued tone, which sounds somewhat like keet. I am 

 informed that quite a number of local collectors have obtained 

 the species form time to time. Dr. Hvoslef reports them pre- 

 sent at Lanesboro, June 1st, 1882.

 slightly tinged with ash on the crown, sides of the head ash,

GEOTftLYPIS PHILADELPHIA (Wilson). (679.) 



MOURNING WARBLER. 



This is another species of the tardy genus Geothlypis, that 

 has been identified, but whose habits have remained quite 

 obscure. I obtained a single individual in typical plumage, on 

 the first day of June, 1869, very nearly within the city limits. 

 Since then I have met occasionally migrants in autumn, and 

 have a few reports from competent correspondents. Dr. Hvos- 

 lef obtained one in high plumage on the 25th of May, 1884. 

 Several local collectors claim to have obtained specimens sev- 

 eral years earlier. Mr. Washburn searched but did not find it 

 where Coues found it previously, "breeding abundantly along 

 the Red river." Their early southern movement may explain its 

 absence at the time the former was in that locality. Mr. Trippe 

 had, somewhat earlier, found it breeding prolifically inMinnesota, 

 but failed to find the nest. He "repeatedly saw the old birds 

 feeding the young in the latter part of June and early in July, " 

 which makes its local breeding assured. He further says: — 

 "They are similar in their habits to the Maryland Yellow- 

 throat, but are not so exclusively devoted to thickets and un- 

 derbrush, frequently ascending to the tops of the tamaracks, 

 for which they show a great jDredilection. " It is to be hoped 

 that more facts regarding its local history may ere long be 

 obtained. Coues says: — "The nest is rather slight, but a neat
