NOTES ON BIRDS OF MINNESOTA. 117 



71. Loxia curvirostra. Very abundant; breeds. I never saw it out 

 of the pineries. 



72. Coccoborus Ludovicianus. Rather common. 



73. Pyranga rubra. Common. 



74. Dolichonyx oryzivorus. Not common. 



75. Molothrus pecoris. Rare. 



76. Agelaeus xanthocephalus. Seen rarely, and only in spring. 



77. A. phceniceus. Not very common. 



78. Icterus Baltimorensis. Rather common. Its favorite haunts are 

 among the tall Norway pines. Arrives about the middle of May. 



79. Quiscalus versicolor. Abundant; breeds. 



80. Q. ferrugineus. Very abundant as far west as the Red River, 

 lit disappears about the middle of May, and returns in September. 



81. Sturnella neglecta. Common on all the prairies. Whether this 

 bird is really distinct from S. Ludovicianus. seems to be rather doubt- 

 ful. The notes of the Western Lark are certainly widely different 

 from the Eastern; and this difference appears to be the main distin- 

 guishing point between them. In Southern Iowa both varieties are 

 to be found; and a series of careful observations satisfied me, that, 

 while 8. neglecta rarely utters the ordinary whistle of S. Ludoviciana, 

 the latter, in turn, though inhabiting the same fields with the former, 

 never gives utterance to its peculiar, warble. Here, the S. neglecta 

 alone is to be found, and I have never heard it whistle in the manner 

 of the Eastern bird. 



82. Corvus Americamts. Common." None remain during winter. 

 In Southern Iowa it is quite common at that time. 



83. Garrulus cristatus. Common. Resident. 



84. Cr. Canadensis. Common; breeds. In summer it haunts the 

 dense gloomy tamarack and spruce swamps, where it breeds. Al- 

 though it is so abundant, I could not find its nest ; but I have rea- 

 son to believe it builds in the tops of the thickest spruce and fir trees. 



85. Lamus borealis. Common in spring and fall. 



86. Vireo solitarius. Not very common; breeds. 



87. V. Novceboracensis. Not common. 



88. V. olivaceus. Uncommon. 



89. V.flavifrons? Rare. 



90. V. gilvus? Possibly V. Philadelphicus. Not common. 



91. Bombycilla Carolinensis. Abundant. 



92. Sitta Carolinensis. Abundant; breeds. 



93. S. Canadensis. Abundant. Less so, in summer, but many re- 

 main to breed. 



94. Trochilus colubris. Rather common. 



95. Alcedo alcyon. Abundant. 



96. Picus pileatus. Not common.
