Alarm Duck

The alarm duck (Stultum clausa plateais) a duck that quacks at the proper time and is used instead of an alarm. They are commonly kept as pets and alarms. You set them by using their nostrils. The left nostril is the hour button and the right nostril is for minutes. When the alarm time comes, the duck quacks very loudly. There are two subspecies of alarm ducks: 24 hour ducks and am/pm ducks.

Subspecies and Cousin
The alarm duck is closely related to those other boring ducks. The am/pm ducks are native to the United States and 24 hour ducks are native to Europe.

This is an example of convergent evolution, in which the two subspecies specifically evolved with the clock system used in specific places. This is also an example of co-evolution, in which the alarm duck evolved to be more precise, as humans evolved the computational abilities to more accurately develop and clock the passage of time.

Anatomy
The alarm duck uses a series of gears and pendula, which grow proportionally to the duck.

Genetics
The am/pm duck has an extra pair of chromozomes, to facilitate the extra equipment required to use a twice-a-day schedule.

Sometimes, a duck is born with a genetic defect that causes it to use an alternative, often varying, time system. These mutants are often favoured by experimental artists, as they defy the arbitrary societal boundaries.
