Ducks often give us the impression of blue, sailor-suited birds who have a penchant for irritability.
Or maybe it's a black duck with a sense of humor matching an equally-appealing bunny. However, here are more
facts about ducks that you probably don't even know.
1. They follow the first thing they see
Scientists call this process "imprinting." Ducks have the tendency
to follow the first thing
they see. This is because they are under the impression that that thing is their mother. Baby ducks usually try to emulate the example of this "being." This is why caretakers feed baby ducks using duck hand puppets, so they can be integrated more in their society.
2. They have some weird parts
When ducks mate, the males develop spiky, corkscrew-shaped genitals. This gives them advantage over rivals when they deposit sperm. Sometimes, females also develop genitals that spiral in the opposite direction. When ducks develop quite the long genitals, they even "lasso" the female back.
3. Not all ducks can fly
There's a breed of duck more common to the penguin than its flying cousins. The Indian Runner cannot fly, but it sure can outrun
4. They can't eat bread
Nope, sorry, your clandestine meetings by the fountain are over. Ducks are omnivorous, but you shouldn't feed them bread. They cause malnutrition, obesity, and even hinder flight.
5. They have three eyelids
This is common with most birds. But ducks have three eyelids because one of them act like goggles that help them see underwater.
6. Tails distinguish the genders
Many breeds of duck are distinguishable by their colors. The curly-tailed ones are males while females have straight and stubby tails.
7. Not all of them quack
Ducks hardly quack. The mallard does, but other ducks croak, squeak, whistle and are even mute.
8. Egg-laying is affected by daylight
Ducks and chicken slow down their egg production if there isn't enough daylight. This is why some introduce artificial light to help with ovulation.
9. Girl ducks are louder than boy ducks
Most female ducks are generally louder and more "talkative." The males are actually virtually silent.
10. They can be indecisive
Really. It's hard for them to make decisions.
