Family ICTERID^I. 

 Genus Dolichonyx Sw. 



122. D. oryzivorus Sw. BOB-O-I.INK. Abundant summer resi- 

 dent. Arrives the last of April and leaves the middle of August. 



Genus Molothrus Sw. 



123. M. pecoris Sw. Cow BUNTING. Common summer resident. 

 Arrives the last of March and leaves in October. 



Genus Agelseus Vieill. 



124. A. phoeniceus Vieill. RED-WINGED BLACKBIRD. An exces- 

 sively abundant summer resident. Arrives the mftldle of March and 

 leaves late in fall.' During October and part of November this species, 

 in company with the Purple Grackle, forage among cornfields during 

 the day, and at night enter the large marshes to roost in myriads. 



Genus Xanthocephalus Bonap. 



125. X. icterocephalus Bd. YELLOW-HEADED BLACKBIRD. Very 

 common summer resident in large marshes. Arrives the first of May. 

 Commences nesting the last of this month. Owing to the restricted 

 localities inhabited by this bird, it is very slightly known among 

 farmers; even those living next the marshes generally think it au 

 uncommon bird. My observations regarding the actions of the males 

 during incubation do not agree with those of Dr. Coues (Birds of the 

 North-west, p. 190). The only difference between the habits of male 

 and female is the slightly additional shyness of the former. Their 

 nests vary endlessly in size, from four to twelve inches in depth, 

 although the latter size is rather uncommon. 



Genus Sturnella Vieill. 



126. S. magna Sw. MEADOW LARK. Abundant summer resident. 

 Arrives the first of March and leaves the last of October. In mild 

 winters a few are resident. 



126a. S. magna var. neglectJk And. WESTERN LARK. A regular 

 but rather rare summer resident upon prairies. A more frequent visi- 

 tant during the migrations. A fine specimen is in the collection of 

 my friend Mr. A. W. Brayton. taken near Chicago the last of May, 

 1876. This form is probably a common summer resident upon the 

 prairies in the western portion of the state. 



Genus Icterus Briss. 



127. I. spurius Bonap. ORCHARD ORIOLK. Ilather common sum- 

 mer resident. Arrives May 12th, leaves early in autumn.
