Ecological relationships of breeding blue-winged teal to prairie potholes Ecological relationships of breeding blue-winged teal to prairie potholes
Ecology of breeding blue-winged teal (Anas discors) was studied on the Waubay Study Area in Day County, South Dakota, in 1965 and 1966. Breeding pair use of the wetland habitat and importance of Type 1 ponds in the wetland complex were evaluated. Changes in breeding pair densities and wetland habitat conditions on the study area were compared for the 16-year period, 1950-66.Blue-winged...

Aging small Canada geese by neck plumage Aging small Canada geese by neck plumage
The neck plumage method, a new technique for separating immature from adult Canada geese (Branta canadensis) in the hand, was evaluated by comparison with the notched tail feather and cloacal examination methods. Two (1.4 percent) of 141 geese examined were misaged, resulting in a 6 percent error in the immature-adult ratio obtained by the neck plumage method. The neck plumage method is...

Selective feeding by juvenile diving ducks in summer Selective feeding by juvenile diving ducks in summer
Waterfowl often fail to use foods that seem plentiful to the investigator. The extent to which selective feeding or rejection of foods is a function of behavioral and morphological adaptations of the species, conditioned behavior of the individual, or individual preference for certain foods has not been appraised. The objectives of our study were to determine: (1) the extent of selective...

Use of flooded timber by waterfowl at the Montezuma National Wildlife Refuge Use of flooded timber by waterfowl at the Montezuma National Wildlife Refuge
Waterfowl use of bottomland hardwood timber stands which were flooded and killed was studied at the Montezuma National Wildlife Refuge, Seneca Falls, New York, from 1962 to 1964. Comparisons of use were made among six habitat types containing dead timber, stumps, and no timber, and with and without emergent vegetation. An index to waterfowl use was derived by direct counts and by counts...
