The Eurasian wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily. It nests on the ground, near water and under cover. It is highly gregarious outside of the breeding season and will form large flocks.
The American wigeon was formerly called the baldpate by ornithologists, and some people still use that name, especially hunters. The diet of the wigeon consists mainly of grass leaves (~80%), other food types eaten are seeds (~10%) and roots and stems (~5%).
The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.

The American wigeon is a bird of open wetlands, such as wet grassland or marshes with some taller vegetation, and usually feeds by dabbling for plant food or grazing, which it does very readily. While on the water, wigeons often gather with feeding coots and divers and are known to grab pieces of vegetation brought to the surface by diving ...
Common moorhens are known to partake in both intraspecific and interspecific parasitism, meaning they will lay their eggs in the nests of other moorhens as well as other species. The frequency of the former increases when there are an insufficient number of nesting sites, while the causes for the latter are relatively unknown.
Falcated ducks have food habits generally consisting of small invertebrate and other insects as well as plant foods. They mainly eat vegetation or insects near to the water, consuming animals such as larvae, crustaceans, and mollusks. They likewise eat plant foods: leaves as well as seeds, grains, and nuts.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Ruppia, also known as the widgeonweeds, [4] ditch grasses or widgeon grass, is the only extant genus in the family Ruppiaceae, with eight known species. [5] These are aquatic plants widespread over much of the world. [3] The genus name honours Heinrich Bernhard Rupp, a German botanist (1688–1719). [6]
