times in spring flocks of other shore birds, but no specimens 
have been taken. 
CALIDRIS LEUCOPHAEA (Pallas). Sanderling. 
Occasional migrant. 
A small fiock of six Sanderlings was seen on March 21, 1902, 
and a single specimen was taken on April 17, 1902. There are no 
further local data for this species. 
Limosa FEDOA (Linn.). Marbled Godwit. 
Rare migrant. 
This large wader, though formerly common, has become quite 
rare. A small flock was seen on the river April 18, 1911. Two 
specimens in the Dankers collection were taken May 8, 1908. 
Limosa HAEMASTICA (Linn.). Hudsonian Godwit. 
Rather rare migrant. 
The Hudsonian Godwit is occasionally seen in small flocks on 
the Missouri River. A group of nine finely mounted birds in 
the Dankers collection were taken on that farm May 15, 1910. 
A few birds were seen April 20, 1911, and a flock of twelve were 
observed on April 28, 1916. 
ToTANUS MELANOLEUCUS (Gmelin). Greater Yellow-legs. 
Fairly common migrant. 
The Greater Yellow-legs arrive from the south from the 18th 
to 22nd of March, becoming fairly common between April 10th 
and 20th and are rarely seen after the first of May (two late 
dates are May 6, 1914, and May 9, 1914). They are found here 
irregularly in the fall from the first of September to the middle 
of November. 
TOTANUS FLAVIPES (Gmelin). Yellow-legs. 
Fairly abundant migrant. 
The pleasing double and triple whistle of the Yellow-legs is 
to be heard on all sides in favorable places when the spring 
flight is at its height, usually from the 12th to 25th of April. 
The migration dates are about the same as for the preceding 
species, except that it remains a little longer on the northward 
flight and arrives earlier on the return, usually about the mid- 
dle of August. 
An exceptionally heavy flight during the latter part of April,
