OF NORTHERN ILLINOIS. 505 



M. palustris Bel., was very abundant October first, as were also M. Lincolnii Bel., Zonotrichia 

 albicollis Bon., and Z. leucophrys Sw. 



33. Euspiza americam Bon. Exceedingly abundant; the most numerous species of the 

 family. Found nesting in grass (nest a foot and a half from the ground), with fresh-laid 

 eggs, June 18. 



34. Hedymeles ludoviciana Cab. ( Guiraca ludoviciuna Sw.) Apparently common. 



35. Cyanospka cyanea Bd. Very common. Found its nests, with nearly fresh eggs, 

 June 24. 



36. Pipilo erythropMhalmus Vieill. Very common. Quite abundant as late as Oct. 12th 



Alaudid^:. 



37. Eremophila alpestris (E. cornuta Boie). One of the most common birds. Very numerous 

 along the roads, its favorite haunts. Apparently raises but one brood, and that very early 

 in the season. (See next list.) 



ICTERID.E. 



38. Dolichomjx oryzivora Sw. Not noticed as common. 



39. Mobthrus pecoris Sw. Much less common than in the Eastern States; in consequence, 

 doubtless, of the comparative scarcity of the smaller birds, its foster parents, as noted in the 

 preceding list. 



40. Agekeus phosmceus Vieill. Common. 



41. Slurnella magna Sw. Very abundant, and as tame as Sparrows. Roads are among 

 their favorite haunts, where, in company with Eremophtta cornida, they will often permit 

 vehicles, and even persons on foot, to pass within ten or a dozen yards of them. 



42. Icterus Baltimore Daud. Rather common, yet far from abundant. 



43. Icterus spurius Bon. Rather less common than the preceding. 



44. Qidscalus versicolor Vieill. Common. 



CoRvnxE. 



45. Cyanura crisiata Sw. Very abundant and half domestic. The presence of this species 

 in cultivated grounds, and its general familiarity, seem due as much to the scarcity of its 

 inveterate persecutors, the Robins, Kingbirds, and other smaller birds, who are so pain- 

 fully aware of its piratical practices, as to the kind treatment it receives from the farm- 

 ers, who not only do not molest it but are pleased with its presence. Young fully fledged, 

 June 20. 



46. Corvus americamis Aud. Apparentl} T not very common in summer. At the West this 

 bird has a better character than at the East ; never, it is said, does it pull corn, and it is 

 much less suspicious, — being perhaps conscious of its innocence, and presuming upon the 

 good treatment from the farmer which it not only merits but receives. 



Tyranxid^;. 



47. Tyrannus carolinensis Baird. Not very common. 



48. Sayornis fuscus Bd. Common. 



49. Contopus virens Cab. Comparatively common. 



50. Empidonax minimus Bd. Not common.
