312 [March, 



Trichas agilts, Wilson. 



Not uncommon. I shot a pair on the 29th of May ; they had mated, and were 

 about to nest. 



Trichas Philadelphia, Wilson. 



Rarely seen. Shot one May 10, 1851. 



*"Vermivora pennsylvanica, Svjain. 

 A few nest in this section. Rare. 



Vermivora chrysoptera, Ijinn. 



Not uncommon for a few days in May. Go north. 



Vermivora rubricapilla,' Wilson. 



Common for two weeks in May on their passage north : they return in Octo- 

 ber, at which time the male is without the chestnut crown. 



*Vermivora celata, Say. 



Not an uncommon species. Frequent the most secluded swamps, where they 

 nest. 



Vermivora peregrin a, Wilson. 



Some seasons, about the middle of May, this plain bird is met Math in great 

 abundance V This was particularly the case May 14, 15 and 16, 1849, when I 

 could have procured any desired number ; they literally thronged on the tops of 

 the bush oaks in an adjoining grove. For the last two years I have not pro- 

 cured a single specimen. 



*Mniotilta VARIA, Yieill. 

 Common. 



Mniotilta borealis, Nuttt? 



I have met with specimens that answered to Nuttall's description, yet I am 

 inclined to consider it a variety of the preceding. 



In order to give some idea of the abundance and great variety of the warblers 

 which visit us, I append a list shot in the forenoon of May 5th, 1852, by Rev. 

 A. C. Barry and myself: 



6 Sylvicola americana, 



1 Sylvicola aestiva, 

 4 " canadensis, 



1 *' petechia, 



4 " maritima, 



1 Setophagia canadensis, 



2 Vermivora rubricapilla, 



2 Trichas marylandica, 



3 Mniotilta varia, 



47. 



All, except three, males in unusually fine plumage, the females not having yet 

 arrived. 



We could Jiave obtained many more of most of the species, had it been 

 desirable. 



Troglodytes ;edon, Yieill. 



Common. First appearance 15th of April. 



Troglodytes hyemalis, Vieill. 

 Common. Nest in abundance on the shores of Lake Superior. 



Troglodytes brevirostris, Nutt. 



A few nest in the vicinity of Racine. Not abundant. 



Troglodytes palustris, Wilson. 

 Abundant on all our reedy flats.
