15. Purple Finch. Carpodacus purpureu^. On October 

 20, 1903, Mr. Anderson received a male of this species from 

 Parkston. Another specimen was received from the same place 

 on March 5, 1904. An effort was recently made to secure some 

 information as to these specimens from the party sending them, 

 but without success. Mr. Anderson says, however, that the 

 birds had been shot, indicating that they probably had not been 

 caged birds. 



PART II. 



Below is given the annotated list of birds for Union county. 

 Only the "point," or southeastern corner of the county, has 

 been under observation. This region includes two large "cut- 

 off" lakes, or old Missouri river beds, several patches of rather 

 dense timber and the timber bordering Big Sioux river, and 

 considerable flat bottom land. 



1. Eared Grebe. Colymhus mgricollis califormcus. Noted 

 on McCook lake on April 22, 1911 (Stephens). 



2. Pied-billed Grebe. Podik/mhus podiceps. It is very 

 commonly seen on McCook and Goodenough lakes, and, no 

 doubt, breeds locally. 



3. Loon. Gavia immer. Noted on April 9, 1916, in back 

 water of the Missouri near McCook lake (Allen, Ludcke). 



4. Ring-billed Gull. Lams dela/warensis. A tolerably com- 

 mon migrant; numerous records in spring of 1918 (Allen, 

 Stephens). 



5. Herring Gull. Lams argentatus. No positive records, 

 though listed in the field notes of various observers. 



6. Franklin's Gull. Lams franklini. A common migrant. 



7. Forster's Tern. Sterna forsterl. This is the species be- 

 lieved to occur with regularity in the spring. Specimens have 

 not been taken, so that we cannot positively eliminate -Sf. hirundo. 

 ]\rr. Allen found this species around McCook lake throughout 

 the summers of 1915 and 1916, and in 1915 it was even more 

 numerous than the Black Tern. 



8. Least Tern. Sterno antillarum. This is a late migrant. 

 On June 2, 1918, twenty-(me were counted about ^McCook and 

 Goodenough lakes. This tern hovers and plunges into the
