Plectrophenax nivalis nivalis (Linnaeus). Snow Bunting 
A common winter resident, found more in the open fields than 
near the lakes and river-courses, and then only where weeds are 
abundant, offering suitable food. 
Calcarius lapponicus lapponicus (Linnaeus). Lapland Long- 
spur 
A common winter resident, arriving about the second week of 
November, and remaining until well into April, the latest date 
at hand being April 17, 1911. More common in the eastern half 
of the county than in the lake region, being more a bird of the large 
open fields. 
Pooecetes gramineus gramineus (Gmelin). Vesper Sparrow 
A common summer resident and breeding species. On June 
17, 1913, three nests were found in a cornfield, all with eggs about 
to hatch. One of our common summer sparrows. 
Passerculus sandwichensis savanna (Wilson). Savannah Spar- 
row 
A regular summer resident, though more common on the early 
spring migration. Undoubtedly a breeding species, though there 
are no nesting records at hand. 
Ammodramus savannarum australis Maynard. Grasshopper 
Sparrow 
A regular summer resident, found commonly but locally. Ar- 
rives during the latter part of April or early May. Probably 
will be found to breed. 
Passerherbulus henslowi henslowi (Audubon). Henslow’s. 
Sparrow 
A regular, though never a common migrant, for which there are 
but few spring, and still fewer fall records. Because of its seclusive 
habits^ it is hard to say how early the bird arrives, but it is most 
apt to be seen during the third and fourth weeks of May. 
Zonotrichia leucophrys leucophrys (J. R. Forster). White- 
Crowned Sparrow 
A regular migrant, more common in the spring than in the fall. 
Found along brush-covered fences and in other thick shelter.
