Morphological differences in Pacific Coast populations of greater white-fronted geese Morphological differences in Pacific Coast populations of greater white-fronted geese

We examined morphological relationships of three Pacific coast populations of Greater White-fronted Geese (Anser albifrons). Adult geese were captured and measured at three breeding areas in Alaska and two wintering areas in California, 1980-1991. A two-step discriminant function analysis examined morphological differences among the three populations. Stepwise discriminant function...

Survival of adult female northern pintails in Sacramento Valley, California Survival of adult female northern pintails in Sacramento Valley, California

North American populations of northern pintails (Anas acuta) declined between 1979 and the early 1990s. To determine if low survival during winter contributed to declines, we estimated winter (last week of Aug-Feb 1987-90) survival for 190 adult (after hatching yr [AHY]) female radio-tagged pintails in late summer in Sacramento Valley (SACV), California. Survival rates did not vary by...

Modified transmitter attachment method for adult ducks Modified transmitter attachment method for adult ducks

The value of radio telemetry for waterfowl research depends on the availability of suitable methods of attaching transmitters. In previous studies, external transmitters attached to adult Mallards (Anas platyrhynchos) with sutures and glue did not stay on birds reliably. In an attempt to improve transmitter retention, a method of attachment was tested in which 4-g transmitters were...

Seasonal predator removal relative to hatch rate of duck nests in waterfowl production areas Seasonal predator removal relative to hatch rate of duck nests in waterfowl production areas

These authors report that hatch rates of duck nests were related to removal of predators from waterfowl production areas. Cost effectiveness of such efforts is questioned. The prairie pothole region (PPR) is the primary breeding ground of several species of North American ducks (Bellrose 1980). Much habitat of breeding ducks in the PPR has been destroyed or degraded by intensive...

Woody vegetation and channel morphogenesis in low-gradient, gravel-bed streams in the Ozarks Plateaus, Missouri and Arkansas Woody vegetation and channel morphogenesis in low-gradient, gravel-bed streams in the Ozarks Plateaus, Missouri and Arkansas

Woody vegetation affects channel morphogenesis in Ozark streams of Missouri and Arkansas by increasing local roughness, increasing bank strength, providing sedimentation sites, and creating obstructions to flow. Variations in physiographic controls on channel morphology result in systematic changes in vegetation patterns and geomorphic functions with increasing drainage basin area. In...

Migratory bird population changes in North Dakota Migratory bird population changes in North Dakota

The status of migratory bird populations in North America has received increased attention in recent years. Much of this consideration has been on Neotropical migrants, especially those associated with eastern forests. The status of migratory bird populations in the Great Plains has received far less attention. During the past quarter-century, populations of many species of birds that...

Conservation Reserve Program and migratory birds in the northern Great Plains Conservation Reserve Program and migratory birds in the northern Great Plains

U.S. Department of Agriculture programs have mediated supply and demand of commodities and maintained the agricultural industry, but several programs have also offered various kinds of conservation benefits. The 1985 Food Security Act (Farm Bill) featured the Conservation Reserve Program (CRP), which paid farmers to plant perennial cover on highly erodible lands and to leave this land...
