xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. [2] Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. [1]

The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under the binomial name Anas penelope. [2] [3] Anas is the Latin word for "duck", and penelope refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea.

Grant coined the binomial name Psittacus fimbriatus. [3] The gang-gang cockatoo is now the only species placed in the genus Callocephalon that was introduced in 1837 by the French naturalist René Lesson. [4] [5] The type locality is the Bass River in the state of Victoria. [6] The specific epithet is from Latin fimbriata meaning "fringed".
Mareca is a genus or subgenus of ducks in the family Anatidae that includes the wigeons.. The species now placed in this genus were formerly placed in the genus Anas.A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus Anas, as then defined, was not monophyletic.

The American wigeon is a medium-sized bird; it is larger than a teal but smaller than a pintail. In silhouette, the wigeon can be distinguished from other dabblers by its round head, short neck, and small bill. [10] It is 42–59 cm (17–23 in) long, with a 76–91 cm (30–36 in) wingspan and a weight of 512–1,330 g (1.129–2.932 lb).
The first bones of this species to be discovered, in 1955–56, were thought to most closely resemble those of a garganey. [3] In 1987 bones of at least 33 individuals were recovered from rock cavities, revealing a very small duck with a short pointed bill like a wigeon's. [5] Strong legs and reduced breastbone and wings show it was flightless.
