spring snipe shooting, the bird has decreased in numbers until 
now it is hardly common. Nelson speaks of a few remaining" 
through the summer in northeastern Illinois (1877), and a 
few formerly spent the entire summer about the Koshkonong 
marshes, but there was never any evidence of breeding. At 
an early day, probably some time in the fifties, Thure Kumlien 
sent June skins to John Cassin, of Philadelphia, and Cassm, 
supposing it sufficient evidence that the pectoral sandpiper 
bred in Wisconsin, published a statement to this effect, on no 
other evidence, however, than the date when the birds were 
shot. It has been stated by different authorities that the bird 
breeds in Wisconsin, but no doubt they can all be traced to 
Cassin's premature conclusions. More numerous in the 
interior than on Lake Michigan. 
Tringa fuscicoHis Vicill. WHITE-RIMPED SANDPIPER. 
Of regular occurrence at about the same time as the next, 
but by no means an abundant species. The white-rumps are 
in fine breeding plumage by the first week in June, and the 
females then contain ora the size of large peas. Small flocks 
of a dozen or less are sometimes found about Lake Kosh- 
konong until the middle of June, and they are back again 
with barely full fledged young by August 1. It thus stands 
to reason that some of them, at least, can not go far north 
to nest. We have no evidence, however, that they ever breed 
in Wisconsin. 
Tringa bairtlii (Coues). BAIRD'S SANDPIPER. 
Regular migrant in small numbers. Most often found in 
May, but frequently in August and up to the middle of 
September. In 1872 and 1873, the years the waders remained 
in such numbers the entire summer at Lake Koshkonong, 
they were the most abundant ever known, before or since. 
With the exception of these two years we have no records of 
summer specimens, and even at that time had no suspicion 
that those remaining bred. Mr. Clark finds this sandpiper a 
regular migrant in Dunn County, and has sent us specimens. 
Contrary to our observation he finds bairdii more common 
than fuscicollis. 
Tringa mi nut ilia Vieill LEAST SANDPIPER. 
Common migrant, especially in May and August. Arrives 
about May 1 and a few remain until well into June. The 
greater part are back again by the middle of August, many
