[B 407, R 264, C 322, U 501 />.] 

 Sturnella magna neglecta (And.). Western Meadow-lark. Mr. 

 Tripp notices it from southern Iowa. In Floyd County it is more 

 common than S. magna, and frequents the outskirts of the towns, while 

 S. magna is usually found on the prairies. 



Genus ICTERUS Brisson. 



Subgenus PENDULINUS Vieili.ot. 



[B 414, R 270, C 324, U 506.] 



Icterus spurius (Linn.). Orchard Oriole. Summer resident; com- 

 mon. Arrives the first week in May and remains until September. 

 Nests in orchards and open woodland.

 [B415, R 271,0326, U507.] 

 Icterus galbula (Linn.). Baltimore Oriole. Summer resident; com. 

 mon from the first of May until September. Its pensile nest is usually 

 attached to the twigs of a drooping branch of some tree. On one 

 occasion bits of twine and strips of colored cloth were placed in the 

 grass near a tree in which a pair of orioles were building a nest, and in 

 the course of a few clays we were in possession of a very interesting 

 specimen of avian architecture, gay with many colors. 



Genus SCOLECOPHAGUS Swainson.

 Scolecophagtis carolinus (Mull.). Rusty Blackbird. Spring and fall 

 migrant; abundant from the middle of March to the middle of May, 

 and from the middle of October to the middle of November. In 

 woodland when alarmed a whole flock, numbering several hundred, 

 will fly to the top of some tall tree and begin a loud, harsh vocalization, 

 which may be heard for a great distance.

Quiscalus quiscula (Rneus (Ridgw.). Bronzed Grackle. Summer 

 resident; abundant from the middle of March to the middle of Novem- 

 ber. In the spring it is not an uncommon sight to see a score or more 

 of these birds following the plow and devouring the grubs and insects 

 that are upturned. In the fall it mingles with the rusty and red-winged 

 blackbirds, frequenting the corn-fields in large flocks. 



"The autumnal migrations of Icteridce at Burlington, Iowa, are notable 

 chiefly on account of the immense flocks of certain blackbirds which
