8i. Pclidna alpina sal'haliiia (X'icillot). Red-backed Sandpiper. 

 JuDD, IQI7, p. i.^ ; fairly common migrant in 1895; first arrivals May 2. 



There is a specimen in the Wilhams Collection, taken at Grafton, May 

 if). 1910, by Mr. Henry Williams. 



In 1920 none were noted in July and August, but one was taken and 

 another seen July 2, 192 1, on the shore of Minnewaukan Bay. Seven of 

 this species were on the Ijeach at Creel Bay, May 7, two on May 16, and 

 three on May 18, 1921. 



82. Brcunetcs pusillus (Linnieus). Semipalmated Sandpiper. 



CouES, 1878, p. 639; abundant species noted at various points during the month 

 of August, one taken at JNIouse River, August 10. 1873. Hoffman, i88j, p. 403; not 

 common near Fort Berthold, McLean County. Judd, 1917, p. 13; equals the least 

 sandpiper in numbers. 



The species was very common after May 9, 192 1, at Devils Lake. As 

 late as May 31, a hundred or more were still there. Two were seen on the 

 return migration, July 18, 192 1. On July 21, 1920, large flocks were seen 

 at a mud pond on the Rock Island Military Reservation. 



83. Brennetes inanri Cabanis. Western Sandpiper. 



Judd, 1917, p. 13; found with the semipalmated sandpipers, which they closely 

 resemble. 



On May 31, 1921, a single western sandpiper was taken from a large 

 flock of sandpipers feeding on the beach at Devils Lake. While this was 

 the only one identified, the species no doubt occurs rarely during the 

 migrations. 



84. Calidris Icucophcca (Pallas). Sanderling. 

 Jiunt. 1917, p. 13; not common, ii'-st date May 28. 



The sanderling seems to be a rather common species in the Devils and 

 Stump lakes region, especially during the fall migration. In 1920 the first 

 were seen at Stump Lake July 24, but it soon became abundant on all the 

 lake beaches and by August 24 it was one of the most common waders at 

 Devils Lake. The first record for 1921 is May 26, at Devils Lake, when 

 ten were noted. On May 31 over two hundred, and on June 10 thirty were 

 seen there. 



85. Limosa fedoa (Linnaeus). Marbled God wit. 



Baird, 18=^8. p. 741 ; records the specimen mentioned below, No. S4So. as collected 

 by Dr. Hayden, but does not give the date. However, it is listed in the Catalogue 

 of the Trowbridge Collection and has the following data: '^Limosa fedoa, Ord. Mar- 

 bled Godwit. Male. Ft. Union, Nebraska (Dakota), July. Lt. Warren; Dr. Hayden. 

 (5450.)" (The specimen is in the Museum of Zoology^ Collection.) Hayden, 1863, 

 p. 175; not common; took one at Fort Union. CouES, 1878, p. 641; a female was 

 taken June 20, 1873, at Pembina, where they were probably breeding. CouEs, 1897, 

 p. 176; August 2, 1843, Bell saw several godwits near Fort Union. Reed. IQ04, p. 

 119; a set of four eggs taken June 10, 1895, at Devils Lake by W. F. Hill. Bent, 

 1907. p. 160; saw about twenty-six godwits in Steele County, June 13, 1901. At
