1914 BIRDS OF ARIZONA ^' 15 



38. Dendrocygna bicolor (VieiUot). 



Fulvous Trisij-ducic. 



Synonym — Dendrocygna ftiha. 



Status — Coues (1866a, p. 98) has recorded the capture of *' a pair taken in 

 November, about twenty miles from Fort Whipple." From a published note of 

 Brown (igo6, p. 217) it would seem to be of fairly common occurrence in winter 

 on the Colorado and Gila rivers, in the vicinity of Yuma, and decidedly rare else- 

 where in the state. 



39. Olor columbianus (Ord). 



Whistling Swan. 



Synonym — Cygmts americanus. 



Status — Recorded by Coues (1866a, p. 98) from the Colorado River and 

 Fort Mohave. There is a recent instance of its occurrence at Sacaton, Pinal 

 County, November 21, 1910 (Gilman, 1911a, p. 35). 



40. Plegadis guarauna (Linnaeus). 



White-faced Glossy Ibis. 



Synonyms — Ibis ordii; Falcinelhis ordii; Ibis guarauna; Ibis thalassimis: 

 Plegadis autumnalis. 



Status — Apparently fairly abundant, as there are records of its occurrence 

 during the migration in various parts of the state: Tucson, Little Colorado Riv- 

 er, Forts Whipple and Apache, and at various points along the Gila and Colorado 

 rivers. It has been reported as breeding at Mormon Lake, in the Mogollon 

 Mountains (Merriam, 1890, p. 88). Has been found at Tombstone in winter 

 (Cooke, 1913, p. 21). 



41. Mycteria americana Linnaeus. 



Wood Ibis. 



Synonym — Tantalus loctdator. 



Status — Apparently common, during fhe summer months, from May to Sep- 

 tember, along the Colorado River, at least as far up as Fort Mohave (Coues, 

 1866a, p. 96). There are also records for the various tributaries of that stream: 

 the Gila, San Pedro, Bill Williams, etc. It is not known to breed in Arizona, nor 

 has it been observed in winter. 



42. Botaurus lentiginosus (Montagu). 



American Bittern. 



Synonym — Botaurus minor. 



Status — The only breeding record is that of Mearns (1890a, p. 51) who 

 found the species nesting commonly in the Mogollon Mountains (Mormon Lake, 

 etc.). It is a fairly common migrant elsewhere and has been found in winter on 

 the San Pedro River in southern Arizona (Scott, 1886, p. 385).
