 these birds were found on the Goose ponds, except the one re- 

 corded March 29, 1913, which was taken about four miles below 

 Marshalltown on Iowa river. 



12. Mareca americana. Baldpate. A rare migrant. On ]\Iarch 

 21, 1914, a flock of four was flushed from a small stream running 

 into Iowa river and a fine male secured. On jNEarch 29, 1915, 

 three Avere seen on the Goose ponds and four more on March 31. 

 These are the only records of the species that the writer has for 

 the region. Most hunters did not seem to know the duck. 



13. Nettion carolinense. Green-winged Teal. An abundant 

 spring migrant from March 14 to May 9. The species was un- 

 usually abundant in 1914, large numbers remaining along the 

 river until April 11 and a few lingering until May 9. It was 

 much less common in the fall from September 1 to October 24. 

 March 24, 1913, Harold Buckwald In-ought in a female wliich 

 was shot the previous day along Iowa river. A male was secured 

 on April 4, 1914, at the Goose ponds. An injured female was 

 found at the same place on September 1, 1913, and one was 

 taken September 5, 1914. Throe were secured on October 4, 1913, 



14. Querquedulcb discors. Blue-winged Teal. The blue- 

 winged teal was the most abundant duck of the section. In the 

 spring migration it appeared from March 15 to IVIay 25, althougli 

 it was most common in late March and early April. In the fall 

 migration from August 22 to November 3, it was nuich less 

 common. 



During the spring migration of 1914, these birds remained 

 in numbers until May 16. As they were undisturbed they be- 

 came very unsuspicious, and it Avas possible to walk slowly 

 within twenty yards of a feeding flock before they flew. A few 

 were reported by Mr. Friese to have remained throughout the 

 summer of 1915, about the Goose ponds. Specimens were col- 

 lected at various times.
