THE BIRDS OF WISCONSIN. 
much later than in the interior. Mr. Clark finds it most 
abundant in Dunn County in August. 
Ereunetes occidental is Laicr. WESTERN SANDPIPER. 
Migrant. Xot nearly as common as the preceding, yet of 
regular occurrence in May and often up to the middle of June. 
We have no state records for the fall, and have never person- 
ally taken it anywhere except on Lake Koshkonong, but it 
doubtless occurs in all suitable localities, a few individuals with 
the large flights of pusillus. Much more readily distinguished 
from the semipalmated when both are in breeding plumage. 
The somewhat larger bill and the extended reddish-brown 
patch at the back of the head are distinguishing characters. 
Caliuris arenaria (Linn.). SAXDERL1XG. 
Common migrant along the shore of Lake Michigan in 
May. August, September and October. Less common in the 
interior, especially of late years. Formerly quite common 
about Lake Koshkonong, and, as with many of the waders, a 
few non-breeding birds remained all summer. Frequents the 
sandy shores exclusively, and not the mud flats like most of the 
shore birds. The winter plumaged adults and young are 
readilv detected among the large flights of smaller sandpipers 
by their lighter colored feathering. 
Limosa fedoa (Linn.). MARBLED GODWIT. 
Formerly not very rare during migrations, but of late years, 
except along the Mississippi and in the northwestern part of 
the state, has almost entirely disappeared. Was not considered 
uncommon by Dr. Hoy in 1852, and a pair seen June 15, 1818, 
on the Wisconsin River, were supposed to be nesting. Thure 
Kumlien took his first pair at Lake Koshkonong, May 25, 
1855. We have seen the bird in Green Bay and on Lake 
Winnebago, but our acquaintance with it in Wisconsin is 
principally from Lake Koshkonong, where it was not rare from 
1870 to 1870, and in 1857-59 it was known to nest in two 
instances, once near Stoughton and once at the lake. There is^ 
in the Kumlien collection a perfect egg taken from the oviduct 
of a female shot May 28, 1878, in the eastern part of Dane 
County. Mr. H. Nehrling gives it as breeding in the northern 
peninsula of Michigan, and it used to nest in Iron County, 
Wisconsin, and almost certainly along Green Ray. At the 
present time one of the rarest of the waders in Wisconsin.
