- A hen makes a loud QUACK sound while the drake has a raspy, muffled call.
- Touching a duckling does not prevent the mother duck from taking care of it. It is however best to leave ducklings alone so as not to scare the mother duck away or accidentally injure them.
- Ducks sleep with half their brains awake. Ducks are more likely to sleep with one eye open when they are located on the edge of sleeping groups. Ducks can detect predators in less than a second.
- Duck eggshells have tiny holes (pores) that allow it to breathe. A hen’s eggs can have 7500 pores, most found at the blunt end of the egg. Respiratory gasses as well as water vapour travel through these pores allowing the egg to breathe.
- Baby ducks are precocial meaning they are born with their eyes wide open, with a warm layer of down and are not fully dependant on their parents for food. Ducklings are ready to leave the nest within hours of hatching.
- A ‘clutch’ is the total number of eggs laid by one bird during one nesting session. Clutch size affected by hereditary and environmental factors. When food is abundant, birds lay more eggs.
