Thanks for the high definition video! I have watched lots of bad baby cuckoo birds done this kind of murdering thing.😤 Still surprised how it be placed in their DNA! 😈 And why the adopted mom didn't react to it?!😓

"Brother, please! Help me!" Cuckoo chick: "Long live the king."

Should find a dozen of those cuckoo eggs and put them all together in a single nest and film the battle Royale.

People: Humans are the only evil beings in this world Cuckoo bird: Hold my beer

I used to tell myself that "Every animal, no matter how vicious, was a baby once." Turns out some animals are little bastards the moment they come into being.

Never have I wanted to punch a bird so bad

Baby bird: Come on bro. Stop pushing me! Cuckoo: I was never your bro.

"accumulate power" i love the wording on this

That’s so fascinating how they automatically know what to do once they emerge from their egg.

That last baby was a real fighter till the end

And they say that... "No one is born a killer..." Yeah, right!

Don't worry, we humans are sometimes much worse than cuckoos and what's worse we do it consciously

“Nature is wise and not evil” Nature:

The other baby's look all cute the cuckoo bird looks like a giant Frankenstein

That last baby fought so hard 😭

こんな事をしてもカッコウの雛を育てる宿主が絶滅せずに、自然のサイクルを現在まで維持できているのはすごい事だ。

生まれてすぐこんなことができるなんてホラー映画より不気味な現実！とても勉強になる動画でした。

marvelous how they're somehow genetically predisposed to do this right after being born

It was soooooo sad to watch how the last baby was fighting for his life before he falls down. 😢

It’s cruel but isn’t it incredible how the cuckoo chick has an innate ability to do what it does?

I'm ready for a cuckoo to get pushed out

託卵されたほうも逆にカッコウの卵を落としたりして防いだりすることもあるから自然界は妙にバランスが取れている。 いい動画でした。ありがとう

This video really triggered me on a deeper level in a way I didn’t expect.

Those poor babies. The last chick that fought hardest, rip.

Born to play among us, real pro gamer move right there

"eat pray and accumulate power" this is how I'm going to describe all forms of feeding from now on.

I never believed that one day I could hate a bird! 😱

Brood parasitism has always fascinated me, especially obligatory brood parasites, I wonder if the babies of the host species will ever evolve a defense

That would be a big twist if the parasite bird layed a egg in a Owl nest an the mother returned when it was laying 😄

My 3-years old son cried 😭. This was his first thriller.

Oww,, poor babies. I was literally crying to watch them falling down.🥺😭

البيت بيت ابونا ويجوا الغرب يطردونا... الكلمات تعجز عن الوصف سبحان الله ما خلقت هذا باطلا سبحانك

بسم الله الرحمن الرحيم " فتبارك الله أحسن الخالقين " صدق الله العلي العظيم ❤🎉

Now I need to watch some videos of eagles killing cuckoo birds...

何が怖いって産まれながらその習性を身につけていること...誰に習わずとも

How it looks like some human politics

Спасибо за видео, очень интересно и познавательно!

"No one is born a killer" Yea, right...

Like if you don’t really like cuckoo birds that much

Other birds comes back and ask, hey Cuckoo why are you alone 😂😂😂😂

Este fantastic ce putere are acest pui de cuc care a eliberat cuibul de oua si puii pasarii gazda el ramanand singurul supravietuitor si cum pasarica ii aduce mancare si l creste ca pe copilul ei Este uimitoare natura cu toate tainele ei😢❤❤❤3

Mummy Bird :"such beautiful children, I must provide for them " Baby cuckoo:"sorry siblings, but I prefer to be an only child " YEEET

Man I was really rooting for the lil dudes

I always thought that as it got bigger it would accidentally crush or push out other chick's. I had no idea it was intentional.

Wild how they evolved to do this. Just some unaware little meat machine shoveling like mad out of instinct.

“Baby cuckoo eat prey and accumulate power” Idk why but I find this statement hilarious

That poor baby bird was fighting for his life against that devil bird... 😭

That little one fought harddddd

(chicks dying) Filmmaker: 😀🎥

Mama bird: "Hello 911...my stepson is a murderer".... operator 911 bird: "Let me guess,he's a Cuckoo"

落とされる時の雛の助けを求めてそうな顔が切ない

Hahahaha, at 0:59 "Baby cuckoo eat prey and accumulate power"

मुझे लगता था कि ये प्रवत्तियां सिर्फ मनुष्यों में होती है । मनुष्य ही दूसरों की चीजो पर अपना सहज आधिपत्य बनाता है । परंतु पंछी भी ..बहुत ही आश्चर्य है ।

The last one fought so hard

this devil bird should replace chicken and be served as meals.

I got Goosebumps watching this , this bird is born evil

Now I know why there's so many baby chicks found on ground when I walk around !!

Now if I see an egg that's a lot bigger than the others it's getting a swimming lesson

As a kid I used to find dead baby birds on the sidewalk near trees where nests were perched and always wondered why that happens. Interesting to see that in some instances it may have been because of a scenario like this. It's a bit unsettling seeing something so innocent as a newborn baby bird committing such a gruesome act as dropping other chicks and eggs to their death

生まれて少ししか経たずにこれやるの凄いな

Bicycle of life 🍵

This chick is more horrifying than anything I have ever seen in the Alien franchise.

It doesn't help that the baby cuckoo looks like 15 times uglier than the other baby birds

The competition for survival But in the end we will all perish, just the difference in time

At a young age, Koko baby realizes that these are not his siblings but why does the mother not know that KoKo Bird is not her child

人の家に子供捨てといて その家の子供捨てるなんて悪魔としか思えないw

they were all like screaming "dont push me out, I dont want to die...." RIP

the ultimate menace

こんな生まれたばかりでもこんな意思のありそうな行動してるの遺伝子ってすげぇな

Every time I see cuckoo chicks I remember my childhood science teacher. She volunteers for a wildlife center an had just got a rescue cuckoo chick found on the ground after a windstorm. It was an awesome month for us to watch him grow. It was only two days old an she showed us that if the chick feels anything in the nest but itself it would push it out. She put a little ball in the nest an within minutes it rotated, stuck it's wings out an backward and used it's naturally shovel shaped back to scoop it up an out. It was really freaky. She also told us if the Mom did notice the imposter an kick it out or leave it the mom cuckoo would attack the host bird viciously to kill it's chicks and would destroy any new nests. Cuckoo's are really devoted to being lazy, lol.

In human law this is the equivalent of an adopted kid killing the legitimate kids.

О боже, так он не только яйца выкидывает, но и птенцов тоже

Nunca tinha visto uma malvadeza assim 😢

The little monster has such an incredible skill, I still don’t understand how it does it 😂

now this is what I call "killer instincts".

Ho.Ly.Sh... That's one of the most brutal things I've seen😬

We can learn many things from these video how to Love each other. 💓

From my very childhood I've been taught that we should be like a cuckoo bird with such a sweet voice and talk to people sweetly rather than being a crow and caw like crows(talking badly). But after seeing this I now can tell all my teachers that a crow is much better than a cuckoo in terms of behaviour🙏

This guy won the number 1 place from all the birds. We can say a seagull is bad for killing baby birds and everything else but this one has the instinct from birth. Even without feathers and not even having his eyes opened yet he knows how to kill.

Это не переворот, а жесткий рейдерский захват.

there can be only one😏thats how it started the story of the Mcleod clan😅

生きてても親の目の前でも雛や卵を落とすというのは見たことがなかったので非常に興味深い

The baddest bird i'd ever knew, how i imagine to roast it

Абсолютный эгоизм,возведенный в ранг величия.

Esto es simplemente una creación divina Porque tanto el polluelo como los padres del cuco están diseñados Para tener este comportamiento esto no es evolución, es creación

Вот гадкий какой! Уже инстинктом заложено! Еще себя не знает, а все ему мешают.....

親鳥が諦めて傍観してるのが悲しすぎる

Has anyone done an experiment on how if an Iron Ball the size of an Egg is combined with a Cookoo Bird, will the Iron Ball also be ejected from the nest?

At first I was sad about this mother nature's creation. But then I got it. Mother nature never creates anything without any purpose. A cuckoo bird is acting as a population control measure for other birds. In this way, it maintains the ecology balance.

Nature is all about experimentation and option. Being selfish or cooperative is both instruments for survival.

Seems like the imposter ejected all the crewmates this round

This is Spartaaaa

Remember folks, in nature there's no such thing as morality: only efficiency

Imagine the reaction of the first people that discovered this.

Parrotbills are so cute.

Бедная птичка в недоумении...а этот противный гадёныш ещё из гнезда всех выкинет.

1:08 Baby bird: “gib me food” Mother bird: *s i t*

Good news guys: we eat cuckoo daily roasting it back at my village 😂

It's so intense knowing it does that right from being born sinister

Predators on the ground near the nest: “Wow it’s raining food!”
