XOTES OX BIRDS OF MINNESOTA. 115 



35. Certhia familiaris. Xot very common; breeds in the tamarack 

 swamps. A nest found May 9th, contained six eggs on which the bird 

 had just begun to set. They were white with a very faint tinge of 

 buff, and sprinlvled with small spots of reddish brown, which are 

 most numerous towards the larger end. 



36. Troglodytes Seivickii. Common ; breeds. I found a nest with 

 seven young just hatched, on the 3d of July. The song of this bird 

 is very similar to that of the House Wren, while in its habits it re- 

 sembles the Winter Wren. 



37. T. cedon. Possibly the preceding species was mistaken for this. 

 The diflferent Wrens are so similar in color and general appearance 

 that it is very difhcult to distinguish them except by close examina- 

 tion. 



38. T.hyemalis. Not common; breeds. 



39. T. palustris. Abundant; breeds. If not tliis species, one that 

 agrees very closely with it in notes, habits and general appearance. 



40. T. stellaris. Abundant; breeds. 



41. Parus atricapiUus. Abundant. 



' 42. Begnliis satrapus. Uncommon; does not breed. 



43. B. calendulus. Uncommon ; does not breed. 



44. Sialia sialis. Abundant. The Bluebird breeds in great numbers 

 in the interminable pine barrens and tamarack windfalls that extend 

 over the greater portion of the northern half of Minnesota. 



45. Orpheus i-nfus. Common. 



46. Turdus miyratorms. Eather common. It frequents the pine 

 barrens, where it finds ample facilities for nesting. It avoids the 

 tamarack regions. 



47. T. mustelinus. Common. The cool, damp woods adjoining the 

 tamarack marshes, are a favorite resort of this and other species of 

 Thrushes. 



48. T. Wilsonii. Common ; breeds. 



49. T. Swainsonii. Rather rare. Does not breed. 



50. T. solitarius. Common. Does not breed. 



51. Saiurus aurocapillus. Common. 



52. Anihus Ludovicianus. Common, appearing by the first of Sep- 

 tember. 



53. Alauda aJpcstris. Common. 



54. Plectrophanes Lapponicus. Abundant. The Lapland Longspur 

 arrives about the middle of September, and remains until December, 

 when it moves further south, its place being supplied by the Snow 

 Bunting. During the depths of winter and early spring it is very 

 niimerous in Southern Iowa, where the Snow Bunting is compara- 

 tively rare. The Longspur remains until tlie middle of May, and very 

 probably breeds within the State.
