The Marbled Duck or Marbled Teal (Marmaronetta angustirostris).
The Common Goldeneye (Bucephala clangula) is a medium-sized diving duck of the genus Bucephala.  Common goldeneyes are territorial and aggressive.  They have elaborate courtship displays.  The common goldeneye is named for its golden-yellow eye. Adult males have a dark greenish glossy head with a white circular patch below the eye.  Their back is dark and they have a white belly and neck. Adult females have a gray body and brown head. Their legs and feet are orange-yellow.  The breeding habitat of the common goldeneye is in the rivers and lakes of the boreal forest across northern North America and northern Russia. They nest in large tree cavities made by woodpeckers and from broken off limbs.  They return to the same nests year after year.  The goldeneye is a migratory waterfowl and spends the winter in the protected waters of the more temperate latitudes.  Their diet is met by foraging underwater for crustaceans, aquatic insects, mollusks, fish eggs and aquatic plants.  This female common goldeneye was photographed while swimming at Walnut Canyon Lakes in Flagstaff, Arizona, USA.

Alstroemeria flower blooming against black background .\nAlstroemeria, commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centers of diversity, one in central Chile, the other in eastern Brazil. Species of Alstroemeria from Chile are winter-growing plants while those of Brazil are summer-growing.\nAlstroemeria, allgemein als peruanische Lilie oder Lilie der Inkas bezeichnet, ist eine Gattung von Blütenpflanzen in der Familie der Alstroemeriaceae. Sie sind alle in Südamerika beheimatet, obwohl einige in den USA, Mexiko, Australien, Neuseeland, Madeira und den Kanarischen Inseln eingebürgert wurden. Fast alle Arten sind auf eines von zwei unterschiedlichen Diversitätszentren beschränkt, eines in Zentralchile und das andere in Ostbrasilien. Alstroemeria-Arten aus Chile sind im Winter wachsende Pflanzen, während die aus Brasilien im Sommer wachsen.
