I visited the spring fed, Portneuf River wetlands along Siphon Rd (Chubbuck) Sunday morning. Open water is still holding a very nice diversity of waterfowl, including about 40 trumpeter swans, mallards, American wigeon, gadwall, northern pintail (1), northern shoveler (3), green-winged teal, redhead, lesser scaup, bufflehead, common goldeneye and 150+ ring-necked ducks.
This location holds half-hardy species in the winter and I was able to find 3 yellow-rumped warbler (Audubon's), 2 Virginia rail and a marsh wren.
