These included two of the filter-feeding ducks (Pink-eared Duck Malacorhynchus membranaceus and Australasian Shoveler Anas rhynchotis), two of the diving ducks (Bluebilled Duck Oxyura australis and Musk Duck Biziura lobata) and a grebe (Hoary-headed Grebe).

Some species, such as Bufflehead (Bucephala albeola), Common Goldeneye (Bucephala clangula), Lesser Scaup (Athya affinis), and Ruddy Duck (Oxyura jamaicensis) have diets that are almost exclusively macroinvertebrates throughout their entire lives (Hoppe and others 1986; Bendell and McNicol 1995; Thompson and Ankney 2002), while others like American Widgeon (Anas americana) consume mostly vegetation during adulthood (Wishart 1983; Knapton and Pauls 1994).

For example, Fulica americana (American Coot), Arias acuta (Northern Pintail), Oxyura jamaicensis (Ruddy Duck), and Chen caerulescens (Snow Goose) all used this modified wetland.

Other waterfowl species commonly observed on the reservoir include American wigeon (Anas americana), gadwall (Anas strepera), bufflehead (Bucephala albeola), Canada goose (Branta canadensis), ruddy duck (Oxyura jamaicensis), wood duck (Aix sponsa), and blue-winged teal (Anas discors).

Two previously described Pleistocene species (Oxyura bessomi and Bucephala fossilis) are placed in extant species.

Laguna Cuyutlan was especially important for american white pelican (Pelecanus erythrorhynchus), ruddy duck (Oxyura jamaicensis), green-winged teal (Anas crecca), and western sandpiper (Calidris mauri), which used the lagoon as a stopover site.

The sample dung was procceed of domestic and wild animal such as: rhinoceros (Rhinoceros simun), dove (Columba livia), dog (Canis familiaris), rat (Rattus norvegicus), cat (Felis catus), frog (Bufo bufo), hen (Gallus domesticus), tiger (Panthera tigris), deer (Cervus elaphus), pig (Sus scrofa), horse (Equus caballus), lion (Felis leo), turkey (Meleagris gallopavo), cow (Bos taurus), duck (Oxyura jamaicensis), donkey (Aquus spp.) and others [4, 7].

THE Latin name for the ruddy duck is Oxyura jamaicensis.
