Agelaius phoeniceus phoeniceus (Linnaeus), lied-winged 
Blackbird. 
Abundant in zone five, to which it is very closely limited, and 
in which, of course, it breeds. Food consists nearly entirely of 
insects, as Chironomus, caddice-flies, Diptera of various species, 
and such beetles as are available. 
Stumella magna magna (Linnaeus). Meadowlark. 
Abundant in zone eight, where the birds nest in considerable 
numbers.

Icterus galbura (Linnaeus). Baltimore Oriole. 
Quite common in the border area of zone seven, especially 
in the elm trees where a few pair nest. Not nearly as common 
as in the region across the lake, which is open and under culti- 
vation. 
Euphagus carolinus (Muller). Rusty Blackbird. 
Common in zone five during the migration, and found occa- 
sionally in zone eight, but in much fewer numbers.
