There are two species of ducks shown here.
The first is the..
Carolina Wood Duck
Aix Sponsa Linnaeus
The females of this species lay between 9 to 14 eggs. Nest dumping, the act of one laying her egg accidentally in the nest of the other when its placed too close to hers may result in overcrowding of the eggs and thus, unsuccessful incubation. Unsuccessful incubation is caused when there are up to 40 eggs in one nest or around this figure.
This behavorial of theirs in accident is known as "nest dumping".
The second duck that you see is one of this species.
Mandarin Duck
Aix Galericulata
They are commonly referred to as Yin Yang ducks, with context with the Chinese culture.They may be a symbol of wedded bliss and fidelity to the Chinese but in reality, these fickle ducks find new partners every year.
