■ Birds of Floyd County, Iowa 133 



I observed four specimens, within the limits of Charles City, on 

 April 25, 1915. 



24. Chen cceruescens — Blue Goose. A rare migrant, though 

 Mr. Waller states that it was formerly common. His last obser- 

 vation is March, 1915. I have no later date. 



25. Anser albifrons gambeli — White-fronted Goose.. A rare mi- 

 grant. Latest observation, Floyd, October, 1915, Mr. John R. 

 Waller. 



26. Branta canadensis canadensis — Canada Goose. A not un- 

 common migrant. Mr. Webster states that this species nested to 

 a slight extent in the county during the '60 s. My latest record is 

 March 17th, 1916. 



27. Branta vernicla glaucogastra — Brant. A rather uncommon 

 migrant, though Mr. Webster states that the species was, during 

 the days of the early settlements, a very common migrant. My 

 latest record is March 17th, 1916. 



28. Branta nigricans — Black Brant. A rare migrant. Latest 

 date, March, 1915; near Charles City; John R. Waller. 



29. Olor columbianus — Whistling Swan. Webster states that 

 these birds were, during the "early days," common, though rare in 

 1897. They have now disappeared from the county's fauna. 



30. Olor buccinator — Trumpeter Swan. Webster states that this 

 species was at one time, during the latter '50's, not uncommon. 

 One was killed near Charles City in 1887. 



31. Botaurus lentiginosus — Bittern. A fairly common summer 

 resident, often nesting within the county. I have frequently come 

 upon them within the limits of Charles City. 



32. Ixobrychus exilis — Least Bittern. A not uncommon sum- 

 mer resident, though rarer than the preceding species. Nests 

 within the county, but on account of its plumage and habits is 

 rarely seen. 



33. Ardea herodias Jierodias — Great Blue Heron. A rather un- 

 common summer resident. A pair nested near Floyd in 1914, and 

 probably in 1915, as young herons were seen by Mr. J. H. Waddell, 

 shortly after the nesting season. Mr. Webster observed one in 

 December of 1914. My first date for 1916 is April 3. 



34. Butorides virescens virescens — Green Heron. A common 

 summer resident, often nesting close to the towns. First obser- 

 vation in 1916; Charles City, March 30th. 



35. Nycticorax nycticorax ncevius — Black-crowned Night Heron. 

 In 1897, and for some years later this species commonly nested 

 within the county. (Webster). The latest nesting record which 1 

 have is in 1913. They are now uncommon. 



36. Grus americana — Wooping Crane. Webster states that
