For example, mallards (Anas platyrhynchos), one of the most common duck species, typically wake up between 30 minutes and an hour before sunrise. This allows them to get a head start on finding food and avoiding predators. Other species, such as the American black duck (Anas rubripes), may wake up even earlier, sometimes as much as two hours before sunrise.
Ducks that live in areas with longer days, such as those near the equator, may wake up earlier in the morning compared to those living in areas with shorter days, such as those near the poles. This is because ducks rely on natural light to regulate their circadian rhythms, and they wake up when the light levels reach a certain threshold.
Additionally, ducks may adjust their wake-up time depending on the season. During the breeding season, when they are actively courting and raising young, ducks may wake up even earlier in the morning to ensure they have enough time to feed and care for their offspring.
