Southern pochard eggs for 20 to 28 days. Once the eggs hatch, the mother leads them immediately to water. The southern pochard eats mainly aquatic plants, which it finds when diving. Also, the adults tend to feed on larvae, pupae, aquatic animals, and plant material. Southern pochard The southern pochard ("Netta erythrophthalma") is a species of duck, and a member of the genus "Netta". There are two subspecies, the South American (southern) pochard "N. e. erythrophthalma" (Wied-Neuwied, 1833) and the African (southern) pochard "N. e. brunnea" (Eyton, 1838). The South American pochard has a fragmented range and is found from Colombia, Venezuela,
Bird-of-paradise lek-type mating system. Others, such as the "Cicinnurus" and "Parotia" species, have highly ritualised mating dances. Males are polygamous in the sexually dimorphic species, but monogamous in at least some of the monomorphic species. Hybridisation is frequent in these birds, suggesting the polygamous species of bird of paradise are very closely related despite being in different genera. Many hybrids have been described as new species, and doubt remains regarding whether some forms, such as Rothschild's lobe-billed bird of paradise, are valid. Birds-of-paradise build their nests from soft materials, such as leaves, ferns, and vine tendrils, typically placed in a tree
