We’d like to thank Daniel from Australia for suggesting we revisit today’s LOVELY Wonder of the Day!

Do you believe in love at first sight? Studies suggest that two out of every three Americans do. If beauty is in the eye of the beholder, what is it about those first glances that stir the hearts of so many?

While love is a many-splendored thing, it’s also very subjective and notoriously hard to study scientifically. A poll of married couples, though, will undoubtedly reveal many stories of people who fell in love with their spouses from the moment they first laid eyes on them.

Animals, on the other hand, make easier subjects of scientific study and offer some interesting insight into the issues of attraction and attachment.

In the early 1900s, German zoologist Oskar Heinroth observed that when young geese were hatched in an incubator and could not see their actual mothers, they instead would become attached to the first human beings they saw. The goslings would act like the people were their parents!

Heinroth believed that the first sight the goslings saw somehow became stamped or “imprinted” on their young brains. Austrian zoologist Konrad Lorenz carried on Heinroth’s pioneering studies of imprinting by closely observing ground-nesting birds, such as ducks and geese.

Lorenz believed that imprinting occurred quickly during a very brief period of time and was irreversible. Lorenz’s observations confirmed what Heinroth had seen.

Kept apart from their mothers, little ducklings would “adopt” as their parent the first thing they saw: human beings or even inanimate objects, such as cardboard boxes, balloons, or balls.

Lorenz’s basic theory of imprinting is well-documented. More recent studies, however, have shown that imprinting may be reversible and not restricted to a critical period. Researchers have also discovered that imprinting occurs in other species, such as insects, fish and some mammals.

Young ducks or geese that imprint on a human being will follow as a group wherever their “parent” leads. In 1993, Canadian Bill Lishman impressively demonstrated this phenomenon when he helped forgetful geese migrate 400 miles from Ontario to Virginia.

Lishman used imprinting to train them to follow his ultralight airplane, becoming the first human being ever to fly in formation with birds! His heartwarming story can be found in his autobiography, as well as the 1996 family film “Fly Away Home.”

    • How AWESOME that you found this other Wonder about LOVE, Aleia! Thank you for exploring Wonderopolis today and leaving us GREAT comments on all the Wonders you’ve visited! :-)

  1. HI!!!!!!!! I believe in love at first sight. Sometimes what you think can be love at first sight, can actually turn out not to be though. I LOVE the movie Fly Away Home. It’s one of my favourites. Sorry if my spelling is different. I’m Canadian.

  2. love at first sight is kinda cool but alot people can think the wrong person is their soulmate. the reason so many people marry or divorce is cause they still looking for the right one or they’ve found the right one ;)

Have you ever wondered…

  • Is there such a thing as love at first sight?
  • What is imprinting?
  • How can imprinting be used to help save endangered species today?

Try It Out

We hope you enjoyed learning more about imprinting in today’s Wonder of the Day. Be sure to check out the following activities with a friend or family member:

  • To celebrate Valentine’s Day, take some time to tell the people in your life how much you care for them. Tell Mom, Dad, Grandma, Grandpa, aunts, uncles, and even your brothers and sisters how much you love them. You’ll never regret telling the important people in your life just how much they mean to you!
  • If you want to show some love for your fine feathered friends on Valentine’s Day, grab a few simple supplies and make some Valentines for the Birds. All you’ll need is some thin wire or string and some yummy treats, such as popcorn, berries, or pieces of dried fruit. The birds in the backyard will thank you!
  • What do you think life would be like if the first thing a young gosling saw after birth was a pig? If imprinting occurred and a group of baby geese believed a pig was their mother, how might things get interesting on the farm? Write a short story that tells the tale of such a situation. Make it as wildly imaginative as you can! Have fun and be sure to read your story aloud to your friends and family members.

Still Wondering
