I have no recent records, but there is a specimen in the Smith 

 collection that was taken locally. 



Chestnut-sided Warbler (Dcndroica ijcnsylvanica) . 



A tolerably common migrant, but very irregular as to occur- 

 rence, being noted only three years out of eight. First seen dates 

 are May 22. 1910: May 26, 1913; and May 24, 1915.

Blackburnian Warb'er (Dcndroica fusca) . 



A rare migi-ant. I identified it in life May 14, 1913, when I 

 saw two males. A few years before this I examined a female 

 specimen which a neighboi''s cat had caught. 



Sycamore Warb'er (Dcndroica doniiiiica alhilora). 



Mrs. George May and her mothei', Mrs. E. B. Haydeii, saw one 

 in Wall Lake May 13. 1913. This was during a great migration 

 "wave" of warblers and other birds. Mr. Joe Abernathy reported 

 cne at Sac City. 



Black-throated Green Warbler (Dcndroica rirens). 



I fiist observed this species August 31, 1912, seeing an adult 

 female which I observed closely fi-om a short d'stance. In the 

 spring I saw one May 12, 1913, and my sister saw the species May 

 15, 1911. and May 22, 1913. It is a rare migrant.

 I saw two in Odebolt. I did not record it again until May 2, 1915. 



Oven-bird (Sciiinis aiirocapillns) . 



A rare migrant. 1 first observed it May 26. 1910, and again 

 May 12. 1914. My sister saw one May 11. 1914. 



Water-Thrush or Grinnell's Water-Thrush (Sciiinis norchoniccnsis 

 norcboraccnsis and iiorchoraccnsis notabilis) . 

 As it is impossible to distinguish between these subspecies 

 without killing the b'rd, I include them both under one heading. 

 A rare migrant. First identified May 15, 1913, and seen again May 

 10, 1914.
