47. Bufflehead (Charitonetta albeola). Common as a winter visitor. 

 Local names: Marionette; Butterball. 



48. Old-Squaw (Harelda hyemalis). A male in full winter plumage 

 was shot on Bayou Barataria February 13, 1899. At the time of the cap- 

 ture of this specimen a severe blizzard was sweeping the South. Zero 

 temperatures were reported at points near the Louisiana coast. The 

 specimen in question is in the museum of Tulane University. 



49. Black Scoter (Oidemia americana). This species has been taken 

 near Lake Catherine. There is a Louisiana specimen in the Kohn collec- 

 tion at Tulane University. 



50. White-winged Scoter (Oidemia deglandi). This species is occa- 

 sionally found on the Gulf Coast in winter. It rarely goes inland. 



51. Surf Scoter (Oidemia perspicillata) . This species also is a rather 

 rare winter visitor. A male killed on Bayou St. John, near New Orleans, 

 on March 20, 1890, is now in the Kohn collection at Tulane University. 



52. Ruddy Duck (Erismatura jamaicensis). This species is a very 

 common winter visitor. Local name: Marteau. 



53. Lesser Snow Goose (Chen hyperborea). Winters in consider- 

 able abundance along the coast. 



54. Greater Snow Goose (Chen hyperborea nivea). Not so common 

 as the preceding, but its movements are about the same. 



55. Blue Goose (Chen ccerulescens) . Rather common in winter on 

 the coast. 



56. White-fronted Goose (Anser albijrons gambeli). Present, like 

 most of the geese, from October to March, or the early part of April. 

 Common. 



57. Canada Goose (Branta canadensis). The commonest of the 

 geese in Louisiana. Its movements are about the same as those of the 

 preceding species. 



58. Hutchins's Goose (Branta canadensis hutchinsii). This form is 

 a rather common winter visitor, and is usually found on the coast. 



59. Brant (Branta bernicla). An occasional winter visitor. 



60. Fulvous Tree-duck (Dendrocygna fulva). Though a native of 

 tropical and subtropical America, this species has been observed in Louisi- 

 ana, not as might have been expected, in summer, but in fall and winter. 

 Considerable flocks have been noted at various times. Its occurrence in 

 Louisiana, however, is decidedly irregular. 



61. Whistling Swan (Olor columbianus) . In recent years, the occur- 

 rence of this species in Louisiana has become very rare and irregular 



62. Trumpeter Swan (Olor buccinator). In the past, this species 

 has proved commoner than the preceding, especially about the mouth 

 of the Mississippi.
