This is like a comedy. Mother bird feeds her chicks and looks at the camera to say "this big fella thinks I don't recognise my own kids" lol

“Feed me, dammit!” “You’re not my child, fuck off!”

Watching this was therapeutic and hilarious, especially after watching video after video of the little bastard cuckoo’s dominating every nest. I love how the moms disposition towards the hungry cuckoo is “Pfft, so?”

that mother bird can see the inside of it's mouth is orange, while her own babies are yellow. She knows that isn't her offspring. I think I love this momma bird, finally one smart enough to not feed the parasite and starve her own. Great video. Made my day!

This is a fascinating dynamic to observe. The biological nestlings don't peck when they are waiting their turn for food, but the cuckoo does, almost as if it understands its true "relationship" with the mother bird.

I just realized the cuckoo makes completely different sounds and movements than the other babies......might just be its downfall

I love how it's trying so hard every time to block out the other babies and mom is just like 'okay i'll just go over you then"

Funny how the cuckooo even blocked all the other baby birds behind, but the mother still find her way to feed them, and left the monster starving.

Mama bird watched too many Batman movies: “I’m not going to kill you, but I don’t have to save you!” 😂

She won't feed it, but she doesn't kick it out, either. She only puts food in the yellow beak. Clever birb.

The cuckoo is either a very late hatcher or it has been deliberately placed in the nest in some kind of "experiment". Normally the egg is laid by the Cuckoo's mother in the unsuspecting host bird's nest and it is timed to hatch out 2 days earlier than the genuine chicks do. They also develop more quickly and are already twice the size of the host bird's chicks, that's if the host eggs get chance to hatch out. That's only if the cuckoo chick hasn't already heaved the eggs out of the nest, using its specially developed back. It is believed that the featherless baby cuckoo has a highly sensitive area on its back which when it comes into contact with anything, it gives it the urge to push it away and out of the nest with its muscular back.When its feathers grow they cover this activation spot and it doesn't have the same eviction urge. Some breeds of cuckoo are happy to grow up with the host chicks, provided they are being fed. But normally they will eject the eggs first or if they are behind their schedule they throw the hatchlings out of the nest with their superior physique. They then have the ability to mimic the sound of the host's brood, which triggers the foster parents instincts to feed the cuckoo. The experts also believe that the cuckoo chick can develop a similar design to its inner throat as the target host chick in order to fool the parents into feeding it. The cuckoo chick in this nest has a totally different colour inside its open beak and this might explain why the host bird isn't feeding it.

That bird got the nerve to try and block the other ones and still got left out! 🤣

Parasite bird: Trying every trick in the book Mother: *Get a job*

I love how the mother bird doesn’t overreact and just waits for the police to arrive

Parasite bird: PLS IM BEGGING U FEED ME Mama bird:looks like everyone is fed already😊

This is the *BEST* video on brood parasitism ever! I think the cuckoo chick made a fatal mistake by allowing its foster siblings to hatch. Evidently, the mother instinctively knows how to distinguish between its own chicks and the imposter. Makes ever more sense now as to why cuckoo chicks must a) hatch before their foster siblings and b) eliminate them while they are still eggs.

Nature can be vicious. I feel bad for the baby. it's pure instinct. But damn nice to see that the others did not all starve or get shoved from the nests like so many do. Guess the cuckoo egg was laid late giving the mothers real babies the ability to hold their own.

You know I always thought this was a really sly move, but it's actually incredibly easy to tell which one the wrong bird is lol. Surely the mother bird notices how one behaves very differently from the other 3, even if they couldn't see color very well and could mix them up, it would be easy to figure out there's 3 of them waiting patiently for food and there's 1 that actively demands and pecks at the momma.

This warms my cold heart.

Great to see a different scenario for once! I am wondering how the rest of the chicks survive having a mean parasite that hatches first and kicks everything else out of the nest!

I love how the mother just stares off thinking "what did I do wrong with this one?"

The mother bird is avoiding being attack by the parasite 🦠 😂 fun to watch, I’m patiently waiting for the three to fledged from the nest because they will be safe from being attack by the old cuckoo, keep feeding your children parents bird 🦅

The other babies make a different noise and have yellow mouths so it's quite obvious that the cuckoo chick isn't theirs and are avoiding feeding it, they know it's a parasite but feed it a little to get by so the mother cuckoo doesn't come and kill the other chicks and destroy the nest.. smart birds.

This is the first time I have seen behavior like this. So the mothet bird found out that it's not her baby? How? Also, it's strange that cuckoo didn't manage to romve the eggs from the nest? What's going on? What's happened next? I'd love to see more!

At first I could not tell the difference between the 4 chicks. The feathers and colour tones all look similar. Then I found that their beak colour differ. The 3 chicks have yellow beak and the parasite chick has slightly orangey colour beak. Good job, Mama Bird! 👍

Id argue its easy to distinguish from the others during feeding because its mouth is not yellow inside like the others

The mom is a smart bird, can recognize her own kids

This is a clever mother bird. She seems to see that there is an imposter

The fact that the cuckoo chick has grown that much shows that it is being fed. I think the reason we see the parent birds feed their chicks and not the cuckoo chick is because they are calling for food at the right pitch that indicates they are hungry. Whereas the cuckoo chick is calling for food at a different pitch than the parent bird is used to. In other videos where we see parent birds feeding the cuckoo chick that’s cuz the really chicks were already starved or thrown out.

每次看到小杜鵑搶不到食物就覺得好痛快啊

It’s also the only one constantly attacking the mom lol

Saya merasa bahagia melihat anak kandung burung bisa tunbuh dewasa

It's probably just video editing out the cuckoo feeding parts because he sure looks healthy

Remember how you'd ask your parents which of their children was their favorite? This mom's not even TRYING to hide it.

Fun fact, this bird evolved to be born with bright yellow throats as a way to deal with parasitic cukoo infestation. The mother will not recognize the bright red of the cukoos mouth and thus will instinctively starve it, while shoving food into the yellow ones.

自分の子が判断できててとても賢い鳥ですね😊

The Parasite: _"Why are you not feeding Mother"_ The Mother: _"Your not my child"_ The Parasite: _"I will non stop pecking you and block of your other child"_ The Mother: _"Don't Care"_

what I noticed most from this video is how the parents, (because ye know this feeding is a two bird job) but how the parents take the faeces and flies away with them. We have a lot of swallows in my town, and it is so irritating how they just poop everywhere. So it is nice to see a bird with a toilet culture

Mama Bird: Only my nice biological children get food.

Okay fair enough to say that the mother bird wasn't impressed by the cuckoo bird begging, and blocked every go to come first before the others and yet still trying to inch forward in the nest the mother went, "nope" and fed her babies. The fact that I appreciate how she got so offended by tge baby cuckoo attacking her also seemed as if she was about to fight but kept her composure

This is an example of birds evolving to be smarter about what’s in their nest, on normal circumstances the mother would give all her attention to the Cuckoo baby but instead she ignores them and opts to feed only her own children, since in a normal circumstance the cuckoo would have thrown the babies out of the nest and increased the odds of outgrowing the nest entirely

Remember that bird was placed there, it hatched and its clueless that its a parasite. It does things out of instinct because that's how nature programmed them. In a way its not the cuckoo bird fault i would be willing to bet that they genuinely think thats his mom

I don’t even know who to feel bad for here. Yes, the cuckoo is a monster but it’s not like he can help it.

Mom's like, "Timmy, your friend has overstayed his welcome and needs to leave." Timmy's like, "Yo, I have never seen this man before in my life."

I've never enjoyed seeing a bird suffer as much as I did watching this video. Mom Bird: "Look, I didnt even know about this sleepover, but your mom didnt leave any food money for you. When is she picking you up again?" Cuckoo Chick: "Picking up?!"

This appears to be evolution in progress. The Cuckoo bird filled a niche by becoming a parasite in the nests of other bird species. But it seems some species have developed the ability to recognize an intruder in their nest and will not feed it.

It's good that the mother knows who her children is

This one failed to evict the other chicks 😂. The mother is being fair feeding everyone

Tbh I can watch this all day it's so satisfying

Natureza maravilhosa 😊😅

Siblings: "Dontcha worry big bro. You can always eat my sh*t."

I'm surprised that, with her displaying the apparent knowledge of the cuckoo not being of her own clutch, she doesn't drag it out of the nest.

His mouth is the wrong color. She knows who her babies are.

Finally! JUSTICE!!! So fun to watch

Parasite Cuckoo: Why don’t you love me like the others? 😅

Well done mommy!

With its size, it looks like a teenager pretending to be a kid.

Getting a taste of its own medicine. So satisfying.

Cuckoo: "But... but MEEEM! MEEEEEEM! MEEEEM!" Mama: "My name. Is not. Meem." Other chicks: "Don't worry Billy! I have something you can eat! HRRRRRGH!" Cuckoo: "AWH WEAK!"

When the little chubbo pecks at her and she just stares him back with one eye like 🧐 not acknowledging his behavior at all 😂

So beautiful ❤❤❤❤

This is one of the most satisfying videos to watch. The cuckoo chick can't get any food.😅

Feel kinda bad for the cuckoo 😢 He didn't ask to be laid in that nest, poor baby is just hungry. As far as he's concerned, that's the only mother he's ever known.

if I were the mummy bird, I would feed the cuckoo bird with my children's poo😉😝

Они его не могут выгнать? Такая наглость

I wish the videos were longer. I don''t mind it not being edited.

0:27 Cuckoo: "Hey, I am here!" Mother: "I know."

For him, it's his mother. He hatched in that nest, and never saw his real mom. I woun't call him monster. He tries to survive

All these comments talking about how they enjoy seeing a baby bird starving. Lets you know who the psychos are, to enjoy an animal suffering. Might be a parasetic bird, but thats literally how they were designed and evolved. It's one of God's creatures as much as the others. And for those that don't believe in God, then the birds evolved like this for a reason and they've survived this long as well as the other species. I could understand if it was invasive, still sad, but to take joy in the suffering of ANY animal is incredibly psychotic.

Very smart mother bird

So satisfying to watch! Momma knoes best! ❤

I love how the Cuckoo desperately tries to get all the attention meanwhile the parent just looks at it like 😐

미운오리를 둥지밖으로 밀어버리면 어떨까?

The mother can tell it's different by how it's acting

"HEEELLOOOO!! FEED! ME!!" "Mm no" 😅😅

I understand the mother bird, but imagine being the baby cuckoo and thinking this is your mom ... and you just can't figure out why she hates you

The color of the inside of the mouth is different between the cuckoo and the other babies. I guess that's how the mother tells who to feed. Anyways, I thought cuckoos pushed the other babies and eggs out of the nest. I guess this is what happens if they don't?

Mother bird: "That's right it goes in the square hole" Parasite: "OH GAWD!"

The mom just looks at him like "Dude, you for real?"

Even though the Cucko is a parasite, it’s still only a baby that doesn’t know why it’s not being fed by it’s mother and that makes me very sad to see

I want to know how far the rejection went. Like did the bird die or what

I'm surprised the momma bird and papa bird didn't peck it until it died... I guess starving it to death was the crueler punishment...

That Cuckoo bird be like "gsss I dont belong here"😂

Mother bird staring at the cuckoo like “wtf”

Feel kinda bad for cuckoo honestly. Not like they asked to be born like that

kind of fascinating how everyone in these comments sort of demonizes the cuckoo, even going so far as to call it "pure evil" or wanting to feed it shit when in reality it's just another baby bird, no different than the others lol. they all just want to survive. not really its fault its mom decided to drop it off on somebody else's doorstep is it

Smartest mommy bird i've ever seen👍

Mother bird is like wtf are you?

It's sad that people say the cuckoo is bad. They hatch from an egg, they don't even know that the bird who kept them warm isn't their mother/father. They are just left there wondering why mom/dad doesn't give them food, and slowly starving to death. They don't know. Stop saying that they are bad and all of that. Nature can do even worse. This hatchling will starve and die, and let the other live. That's how it works.

Dem birds are getting smart XD

The parent birds still feed it, the fact that it still remains on the nest, but is given the lowest priority.

🎶One of these things is not like the others, One of these things just doesn't belong.🎶

What a sonovabich, it's attacks the mother when not get feed XD

Yes if the mother's chicks survive without being tossed out of the nest, the mother is less likely to feed the cuckoo. She can identify her chicks by their appearance and cry. Though the cuckoo tries hard to mimicry, in this instance, the cuckoo is doomed.

I really love the moter bird feeding her chicks and nothing for the cuckoo's chick😊 One of the best video I've seen ❤ Thank you!

It’s like the bird knew it wasn’t its child. Great video. 謝謝你的視頻

This is interesting and surely unusual, as baby cuckoos normally eject the chicks and eggs of the host, when they are very young. The baby cuckoo has clearly been fed up till this point but the parent now knows it is wrong. Can you please tell us what species of host bird it is and what species of cuckoo (if you know) and what part of the world? I assume Asia somewhere.

Very smart momma, tho I do kinda feel bad for the cuckoo chick, still that's nature I guess. Stay frosty!

That mama bird was looking at the camera like ... Nope 😅

I feel like the cuckoo birds behavior is its own downfall sometimes. Notice how the other birds just sit there with their mouth open nothing to extreme.. however the cuckoo stoops low and raises its wings.
