middle of January. A strong northward movement begins at that time, 

 and while it consists largely of individuals that have wintered in Louisiana,, 

 it is doubtless augmented also by the first passage of transients. This 

 later movement continues more or less freely until about March 15, after 

 which date, duck migration is restricted almost entirely to a few species, 

 among which the Gadwall is seldom if ever found. 

 Local names: Gray Duck; Canard gris. 



35. Baldpate (Mareca americana). Though rather less common 

 than the preceding, this species exhibits about the same movements. 



Local names: Zin-zin and Widgeon. 



36. Green-winged Teal (Nettion carolinensis) . At no time as com- 

 mon in Louisiana as the Blue-winged Teal becomes there in spring, the 

 Green-winged Teal is present in large numbers for a greater period than 

 the Blue-winged Teal. Numbers arrive in the fall not later than October 

 1, thus preceding most of the other species. They are particularly abun- 

 dant in fall. Many remain in southern Louisiana throughout the winter, 

 departing, with the bulk of the winter ducks, early in February. Individ- 

 uals that winter extralimitally are rather late in returning, but the aver- 

 age time of their spring flight is much in advance of that of the Blue-winged 

 Teal, so that the last have usually passed before April. 



Local names: Cognotte; Sarcelle d 'hi ver (Winter Teal). 



37. Blue- winged Teal (Querquedula discors). Leaving aside the 

 possible occurrence of this species as a breeder in Louisiana, it is neverthe- 

 less present there for a large part of the year. Returning transients appear 

 in Louisiana between September 1 and September 15. Individuals of 

 this class continue common throughout the fall and with those arrivals 

 that will remain throughout the winter make the species abundant until 

 cold weather in November. From then on, the numbers are decidedly 

 decreased until the middle or latter part of March, when the bulk of tran- 

 sients begin to arrive, the transient movement continuing in force until 

 the first half of May, while the writers have positively recorded the species 

 in southeastern Louisiana as late as May 21. Some hunters claim that a 

 few of this species breed regularly in southern Louisiana, and it is not at 

 all unlikely that such is the case. No authenticated instances, however, 

 have come under the observation of any of the writers. 



Local names: Sarcelle autonniere; Sarcelle printanniere. (Spring 

 or Fall Teal). 



38. Cinnamon Teal (Querquedula cyanoptera). This species is rare 

 in Louisiana. All specimens recorded have been taken in fall and winter 

 in the southern part of the State. 



39. Pintail (Dafila acuta). In one important particular, the move- 

 ments of the Pintail in Louisiana differ from those of the Mallard, Gadwall, 

 and associated species. The spring transients are the latest of all ducks 

 except the teals and the Shoveller, and this in spite of the fact that winter 

 visitant individuals, as with similar individuals of the Mallard, move: 

 northward very early, probably never later than the middle of January.
