Fort Peck Reservoir and the Missouri rovide the most heavily-used waterfowl habitat in the area (Carlson , c.)- These two areas, however, were not studied intensively, and field s concentrated on stockponds on and near the proposed mining area, the mine study area, the only important wetland habitat was provided by Creek and its tributaries, and by the larger, older stockponds. Populations. Seventeen species of waterfowl were observed in the study areas during 1977 (table 8). Table 27 shows monthly species composition of all recorded waterfowl observations made during 1977; these same data are pre- sented graphically as percent species composition in figure 36. Also shown is the species composition of breeding (May-July) populations. It is evident from these data that the mallard is the predominant waterfowl species during most of the year, and that the mallard, American wigeon, and blue-winged teal are the principal breeding species. The Canada goose, gadwall, pintail, and green- winged teal were most frequently encountered during MAR APR AUG SEP OCT MONTH yr-long ave. breeding season oily Figure 36.
