A model of the productivity of the mallard duck A model of the productivity of the mallard duck
This paper describes a stochastic computer model that simulates recruitment of the mallard (Anas platyrhynchos) under different habitat conditions and management scenarios. The model incorporates several environmental phenomena and biological relations that affect mallard recruitment. Major events include arrival of mallards in the spring, daily survival of hens, initiation of nests...

Northern pintail body condition during wet and dry winters in the Sacramento Valley, California Northern pintail body condition during wet and dry winters in the Sacramento Valley, California
Body weights and carcass composition of male and female adult northern pintails (Anas acuta) were investigated in the Sacramento Valley, California, from August to March 1979-82. Pintails were lightweight, lean, and had reduced breast, leg, and heart muscles during August-September. Ducks steadily gained weight after arrival; and body, carcass (body wt minus feathers and gastrointestinal...

Renesting Characteristics of Captive Mallards on Experimental Ponds Renesting Characteristics of Captive Mallards on Experimental Ponds
Renesting characteristics of captive wild-strain mallards (Anas platyrhynchos) were investigated on experimental ponds in southcentral North Dakota during the breeding seasons of 1976-81. Renesting efforts and egg production increased during the 1st 3 years. Post-yearling females that experienced clutch loss during early incubation produced 3 clutches of eggs during the breeding season...

Waterfowl harvest at Tule Lake National Wildlife Refuge, 1936-41 Waterfowl harvest at Tule Lake National Wildlife Refuge, 1936-41
Waterfowl harvest at Tule Lake National Wildlife Refuge (NWR) for the 6-yr period 1936-41 is described and compared with a recent (1978-83) period. During the early period 46,987 geese and 76,143 ducks were bagged during 48,610 hunter-visits. Hunting seasons were 30 to 60 d in length. Greater White-fronted Geese Anser albifrons, followed by Northern Pintails Anas acuta, and Cackling...

A comparison of burn season effects on nesting birds in North Dakota mixed-grass prairie A comparison of burn season effects on nesting birds in North Dakota mixed-grass prairie
During 1982-1985, the effects of single spring and fall burn treatments on ground nesting birds and residual cover were studied on five paired areas of native mixed-grass prairie in northwestern Stutsman County, ND. Annually, visual obstruction readings to index the height-density of residual cover were taken once and nest searches were made four times on each area. Residual nesting...

Western Stump Lake, a major canvasback staging area in eastern North Dakota Western Stump Lake, a major canvasback staging area in eastern North Dakota
Large numbers of waterfowl, especially canvasback (Aythya valisineria), used Western Stump Lake as a staging area during most of October 1985. Selection of the lake as a conditioning site by this species likely is caused by extensive, shallow-water beds of sago pondweed (Potamogeton pectinatus) and lack of human disturbance. A brief limnological and historical account of the lake is...

Molt chronology of northern pintails in California Molt chronology of northern pintails in California
Intensity and chronology of molt in 10 feather groups (head, neck, breast, belly, back, rump, side, scapular, tertial, and tail) were measured using percentages of developing feathers (pinfeathers) converted to molt scores (0-100) in samples plucked monthly from northern pintails (Anas acuta) collected by shooting from August through March 1980-82 in the Sacramento Valley, California...

Nest sites of ducks in grazed mixed-grass prairie in North Dakota Nest sites of ducks in grazed mixed-grass prairie in North Dakota
Habitat use and nesting success of seven species of dabbling ducks were evaluated in five vegetative associations within grazed mixed-grass prairie in central North Dakota. During 1976-80, 548 nests were found on 412 ha of grazed prairie for an annual average density of 27 nests/100 ha. Numbers of nests found ranged from 1/100 ha in 1977 (a drought year) to 58/100 ha in 1979 (a very wet...
