1914 BIRDS OF ARIZONA 15 



38. Dendrocygna bicolor (Vieillot). 



FULVOUS TREE-DUCK. 



Synonym Dendrocygna fuk'a. 



Status Coues (i866a, p. 98) has recorded the capture of " a pair taken in 

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

 Brown (1906, 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 (Ond). 



WHISTLING SWAN. 



Synonym Cygnus americanus. 



Status Recorded by Coues (i866a, p. 98) from the Colorado River and 

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

 County, November 21, 1910 ( Oilman, 191 la, p. 35). 



40. Plegadis guarauna (Linnaeus). 



WHITE-FACED GLOSSY IBIS. 



Synonyms Ibis ordii; Falcincllus ordii; Ibis guarauna; Ibis thai as sinus ; 

 Plegadis aiituninalis. 



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 loculator. 



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

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

 i866a, 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 (iSoxia, 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).
