What Actually Makes Water Roll Off a Duck's Back? | Deep Look
Ғылым және технология
Ducks and geese spend a lot of time preening their all-weather feathers. This obsessive grooming - and a little styling wax from a hidden spot on their back side - maintains the microscopic feather structure that keeps them warm and dry in frigid waters.

Summer is a great time to be a bird watcher in California. Ducks, geese, and many other species of aquatic birds come to California to breed, build nests and raise broods. If you go to your local pond right now, chances are good that you will see a mallard or Canada goose paddling along with a gaggle of its offspring in tow.
But watch for too long and you might find yourself wondering “how do these birds stay warm and dry in the water?”
It’s a question that Jack Dumbacher, curator of ornithology and mammalogy at the California Academy of Sciences in San Francisco has been asked many times.
The secret to waterproof waterfowl, it turns out, lies in their feathers.
“Aquatic bird feathers are really different than those of other birds,” Dumbacher said.

What do ducks eat?
Ducks eat a lot of different things, from snails and tadpoles to grass and fruit. Some ducks specialize in a certain food like fish, while others are more general in their appetites.
Is it OK to feed bread to ducks?
Bread is like junk food to ducks and geese because it doesn’t contain the nutrition they need from their typical diet in the wild. Foods like insects and aquatic plants contain more nutrients than carbohydrate-rich bread.
How do ducks float?
In addition to keeping them warm and helping them fly, ducks rely on their feathers to make them buoyant in water. Soft fuzzy down feathers keep a layer of warm air next to the bird’s skin. The larger vaned feathers create the contour of the duck and keep water out.

This 2016 study by scientists at the University of Debrecen in Hungary, shows that aquatic birds like ducks and geese not only have feathers with denser, more tightly knit microstructures than their terrestrial counterparts, but they also have more of them.

Growing up, we had a lot of ducks and I would sometimes play with the feathers when I see them on the ground. I would always separate them like at 2:41 and would put them back together. It was kinda satisfying. Now I learned why that was possible. Also, I didn't know they waxed themselves. Neat! I love birds and I am continually getting fascinated by them. Thanks for another great video!

I had to study feathers in my university course for Animals. And I can be safe to say that this info is correct. Bird feathers are amazing. There's wing feathers, contour feathers, down feathers, bristle feathers etc. and it's so amazing to know! The barbs are pretty cool too!

"aAnd...gOr𝓰𝓮𝓸𝓾𝓼" was perfectly timed with the duck staring at the camera.
Thankfully this youtube channel was not influenced to make demoralizing content. Its just beautiful what nature has to offer. We could aquire so much knowledge from analyzing these cool creatures
How good you are, DL? That's a fantastic work you've done on this one release, thank you! To the whole Team!
When I was younger, we would do arts and crafts stuff and there would be artificial feathers. I would always try to make sure the feathers didn’t have any breaks in them. Funny how I was sort of preening the feathers (with out the grease of course)
Such a complex design just on the feathers, and how was this natural selection. it’s like if someone actually thought out exactly how this should be, not just some casual thing that happened to be useful and made them survive
Just finished my Deep Look binge, appreciated every one of them! Learned abou the uropigeal gland but had never seen one!
Quack ! Quack!🦆🦆
This video looked STUNNING in 1080p!! Can't imagine what those gorgeous feathers would look like in 4K!!!
Imagine having to re-zip your jacket everytime you move! I respect these guys even more now.😉🦆🦆🦆

Watched this with a smile on my face the entire time. I love ducks and geese.
Awesome video, I really like how you folks are able to visualize the tiny details of the feathers, I'm still not sure how they zip their barbs together with that unstable movement though. But still, you guys are really underrated.

thanks for this informative video, interesting, keep up the good work.
Some gorgeous shots in this! Simply *stunning!* I knew how it all works, but when I am missing the little Canadian gosling that we rescued and delivered to a waterfowl rescue place a few years ago (has it really been over 5 years?!?), I hunt down things waterfowl-related to watch. Before anyone claims I didn't know what I was doing, that her mom was probably just off eating, let me explain a few things. I understand birds. I've raised chickens, ducks, quail, guinea fowl, turkeys, and geese successfully, for years. I get the whole "mom went to get some food, the chicks will be fine" thing. I do. I have seen it time and again. However, I've had to explain this SO often, so I'll get it over ahead of time... We had a tornado rip through the countryside between our home and my sister-in-law's home; passing really close her house & near/over a fee small lakes. Next morning, my sister-in-law discovered a lone little gosling (I estimate perhaps as young as 2 days), walking down the dirt road past SIL's home, crying as loud as she could for mama. No mama in sight, muddy and chilled, and as soon as she saw my sister-in-law, she sped up and ran straight at her. I assume an instinct told her that something larger than her would be needed so she could get help. This being March, SIL was amazed the gosling even survived overnight alone! She came right up to SIL, kept begging, and wouldn't leave her side. When SIL moved (she was doing chores), the gosling followed her. SIL moves again, gosling follows again. So, it was clear to SIL she was stuck with a bird she knew nothing about & was in over her head, so she got hold of me. I picked up the adorable little girl, set up an area for her with food & water, and started looking for the best waterfowl rehabber in the area. Got hold of a friend who used to rehab wildlife, herself (mammals), knew one personally, and enthusiastically suggested her. We named the gosling Dandelion Daffodil, as the dandelions seemed to be her favorite thing to chomp on from the yard, it was still blooming season for daffodils, and she still had the yellow tone in her fluff; it seemed to fit. 😄 That was the name she was taken in with, too! 😍 To make a long story slightly less long than it would've been, I only got not quite 5 full days with Dandelion, but it was long enough to fall in love with her! She grew up, migrated with the rest of the geese there, and came back to the rehab release point the following season! She was doing great the last time I checked in with them, too. 🦆❤ They only follow them for 5 years, so I won't know when her story ends, but they can live to 15 years old (older in captivity, but that's not a normal life), so I will just assume, from here on out, she will live a continued long, happy life! Good grief, sorry that was so long! It just brings back so many memories!
