94. Passerculus savanna. Not very common; breeds. An 
inhabitant of the bushy margins of pools and water-courses on the 
prairies. 
95. Coturniculus passerinus. Abundant; breeds. 
96. Coturniculus Henslowii. Common; breeds. Prefers the 
edges of hazel copses, while the preceding haunts the open, grassy 
prairies. 
97. Chondestes grammaca. Rather common; breeds. Ar- 
rives late in April, and departs in August. The song of this bird 
is exceedingly loud and sweet. ; 
98. Gonotrichia Gambellii. A specimen shot in sprin 
Decatur County, agrees precisely with Baird’s description. 
99. Zonotrichia albicollis. Abundant; spring and fall. 
100. Zonotrichia querula. Abundant in Decatur County in 
spring and fall; not observed in Mahaska. This beautiful spar-, 
row is one of the commonest of the Fringillide that pass through 
Decatur County in fall and spring, associating at such times with the 
other sparrows and finches, and frequenting similar haunts. Its notes 
in the fall are a simple loud chirp, not distinguishable from that of 
the white-throated sparrow, and, occasionally, a low, sweet warble; 
in the spring it has a curious song, beginning very much like that of 
the latter bird, but ending with a few harsh, drawling notes, sound- 
ing like a faint mimicry of the scream of the night hawk, and totally 
unlike the first part of the song. 
101. Junco hyemalis. Rather common in the spring and fall; 
in winter less frequent, many of them going south to avoid the ex- 
treme cold. 
102. Spizella monticola. Common; spring and fall; but, as 
is the case with the last, many go south during the depth of winter. 
103. Spizella pusilla. Abundant; breeds. 
104. Spizelia socialis. Common in Mahaska; breeds. Seen 
but seldom in Decatur. 
105. Spizella pallida. Common in spring, in Decatur County, 
but not seen in Mahaska. This bird frequents the thickets and 
copses along the margins of woods, and has somewhat the habits of 
the redpoll, feeding on the buds of the elm and other trees in early 
spring. 
106. Melospiza melodia. Abundant in spring and fall, but 
not observed to breed. Shy and retiring, —a complete contrast to 
the eastern song-sparrow.
