“…The bays and inlets typical of ponds with Shoreline Development Index > 1.5 seemed particularly important on those ponds that lacked extensive emergent vegetation. Brood association with irregular shorelines has also been shown by Mack and Flake (1980), Hudson (1983), and Belanger and Couture (1988). Security from predators is also the reason we believe deeper ponds were preferred.…”

We studied waterfowl use of grass-sage stock ponds in north-central Wyoming during the 1988 and 1989 breeding seasons. Dabbling ducks, particularly mallards, were the most common breeders. Indicated breeding pair density averaged 2.7 pairs/ha of wetland surface, while brood density averaged 1.0 brood/ha of wetland surface. Waterfowl use and productivity were greatest on large (>3 ha), clear, deep ponds with grass shorelines and abundant submergent macrophytes. Pair use was positively correlated with water clarity, pond area, and macroinvertebrate diversity. Brood use was related to macroinvertebrate diversity, pond depth, and Shoreline Development Index. We recommend management priority be given to ponds that are deeper than I m to provide more water that is clear so macrophytes can be established. Macroinvertebrates should be artificially introduced into ponds. Fencing should be used to improve ponds for waterfowl use and brood rearing.

“…Adding terraces to open water ponds can also increase habitat interspersion (mixing of open water and vegetated marsh habitats) by increasing the amount of emergent vegetated edge in open water ponds. A relationship between interspersion and wetland use by waterbirds has been noted for marshes elsewhere (Weller and Spatcher 1965;Mack and Flake 1980;Kaminski and Prince 1981;Murkin et al 1982;Fairbairn and Dinsmore 2001). Thus, increasing the proportion of marsh edge around the perimeter and interior portions of marsh ponds could improve habitat quality for waterbirds.…”

We evaluated the influence of marsh terracing on waterbirds in Louisiana's Chenier Plain. Terracing is a novel technique used to slow coastal marsh loss. Terracing increases marsh edge and is assumed to slow erosion, decrease pond depth, and encourage vegetation production. From April to September 2005, we monitored waterbirds in paired terraced and unterraced ponds in three sites dominated by Spartina patens. We additionally sampled submerged aquatic vegetation (SAV) biomass, nekton density, and water quality. Waterbird density and species richness were 3.8 and 1.4 times greater, respectively, in terraced ponds. By foraging guild, probers, aerial foragers, and dabbling foragers were more abundant in terraced ponds. Waders were frequently more abundant in terraced ponds. Diver density did not differ significantly between pond types. Terracing increased marsh edge in ponds 3.5 times. Nekton and SAV were more abundant in edge habitat than in open water, but water quality, water depth, SAV, and nekton did not differ significantly between pond types and did not influence bird density. Bird densities were higher in ponds with greater proportions of marsh edge, possibly because they are morphologically constrained to forage in shallow water or because of abundant food near edges.

“…Haland (1983) found that interactions between mallard broods were infrequent, however, and brood spacing was brought about by mutual avoidance. Brood density has been shown to increase in response to an increase in food supplies (Godin & Joyner 1981, Talent et al 1982 and is higher on lakes with a large amount of shoreline in relation to water area (Patterson 1976, Mack & Flake 1980, since shoreline is the main feeding habitat of Mallard ducklings (Pehrsson 1979). In the United States ponds experimentally sprayed with a pesticide used to control spruce budworm Choristoneura fumiferana produced significantly fewer invertebrates, which had dramatic effects on the survival of Black Duck Anus rubrzpes and hlallard ducklings (Hunter et ul.…”

The survival of Mallard Anas platyrhynchos ducklings was studied on a complex of flooded gravel quarries in England and their weight changes in response to invertebrate predation by fish were studied by experiment. The majority of duckling loss occurred during the first 12 days after hatching but those feeding on the river where fish were scarce survived better than those feeding on lakes where fish density was high. Duckling mortality was higher in broods with large home ranges. In the experimental trials an increase in fish density was related to a reduction in both the number of emerging invertebrates and the biomass of aquatic macrophytes. Ducklings feeding in these ponds travelled further and gained less weight than on the pond with a low fish density where the number of emerging invertebrates was higher.
