Agelaius phoeniceus phoeniceus (Linnaeus) . Red-Winged Black 
Bird 
An abundant summer resident, breeding in practically every 
swamp in the county. The males arrive about the second week 
in March, and are followed by the females after an interval of 
about a week. In the fall they congregate in immense flocks, 
often alighting in the grain fields, and it is then that the farmer 
plays havoc among their ranks. 
Stumella magna magna (Linnaeus). Meadowlark 
A very common summer resident, found from the middle of 
March until the heavy frosts of late October or early November. 
Public sentiment is slowly swinging in favor of this bird, and it is 
far less “hunted” than formerly. 
Icterus spurius (Linnaeus). Orchard Oriole 
A regular summer resident, found in the less populated sections 
of the county, and but seldom seen in the vicinity of Oconomowoc. 
Icterus galbula (Linnaeus). Baltimore Oriole 
An abundant summer resident. The birds return year after 
year to a favorable nesting site, and a pair has nested on one of 
two adjacent branches of a large elm for four consecutive years. 
Euphagus carolinus (Muller). Rusty Blackbird 
A common migrant, arriving during the first week of April, 
and returning again during November. Seldom found in large 
flocks, as are the other blackbirds. 
Quiscalus quiscula aeneus Ridgway. Bronzed Grackle 
A very common summer resident, becoming superlatively 
abundant in the fall. During September the birds congregate 
in perfectly enormous flocks and invade the cornfields. Here 
they are slaughtered by the farmer. During the nesting season 
they are less gregarious, and solitary nests are common. 
Hesperiphona vespertina vespertina (W. Cooper). Evening 
Grosbeak 
Not an uncommon, though very irregular and erratic winter 
resident. Most of the records for the species are in February. 
On February 8, 1911, a flock of eight which remained in a very
