[@Swanicorn]

@@German_Shepherd_Mom I know but what I am saying is, how is the intruder bird's starving and suffering, making your day? Nothing wrong is being done by THIS particular cuckoo. I could understand if this specific "parasite" actually acted like one: kicked the other eggs and chicks off the nest. But has this one done any of that? So why are you rooting for this specific one to suffer for whatever previous experience you have about other cuckoos? From a scientific perspective if "parasite" chicks like this survive, there is a high chance such behaviour will be more common from its future babies, where the intruder doesn't aggressively kick off the real babies etc. That's evolution for the better!

[@Swanicorn]

@Absalom Jones If your parents abandoned you as a baby at someone's door and those strangers decided to take care of you, that's adopted. If they put bleach and concentrated sulphuric acid on you and then kick you out of view to get rid of you yeah then I can understand. I mean the owners of the house have the choice! Why should they choose to share their food with you! They will starve surely if they take you in right? And all of that stuff that you are saying, has this particular baby done it? Generalizing? I can attribute all the atrocities done by humans and say the same in general about all humans. It's really bad to have this revenge mentality, I wish you will understand that soon.

@Absalom Jones What are you talking about??? HELLO? Good morning. Wake up brain. I said YOU, as a baby. How would anyone know what all menace you would do as a baby? That's the revenge mentality. How would the house owners know that you are a threat? Not talking about the bird. Hello again wake up if asleep. Talking about you as a baby, abandoned by your mother. You know? In the past mothers actually used to do that. How is anyone supposed to know if you will grow up to become Osama bin Laden or Gandhi? The fact that you know, is the revenge mentality.

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.

[@ryomensukuna8590]

Nice explanation. Thanks

[@goognamgoognw6637]

You say this brood was messed with by someone adding a cuckoo chick, but i've seen cuckoo with other hatchlings and the cuckoo is always easy to indentify and had a red color inside the beak that other hatchlings do not have. Also if as you say cuckoo would be so efficient at killing the host bird hatchlings they would push their host specie to extinction. So sometimes they loose in their parasiting plot, this video might be such a case. And who says the mother isn't feeding the cuckoo, maybe she makes sure all get fed.

[@Discordia5]

​@@goognamgoognw6637You're right. The mom is feeding them all at least a little bit. Her own babies are likely just getting better treatment.

[@epNian]

From what I remember, the cuckoo indeed hatched there before the others, but the way the nest was placed the eggs didn't fall out, and when they did(I don't remember if they did) the mother picked them up, there is no a huge fall to crack them. The author found the nest and installed the camera, they didn't messed the nest. It was only the father who gave the cuckoo food, I think that is why smaller than other cuckoo at that stage

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.

Depends on the cocoo species. Cocoos are a very interesting species some do not push out their silblings, some do. Might also be an individual abnormality. Best guess is that the mother does not feel stimulated to feed the strange chick because she has the right stimuli in her nest (her own chicks) and they have a different color inside their mouth. Birds get stimulated by the pattern and colors inside the mouth of their chicks. There are some real wierd chicks with freaky mouth patterns out there.

[@Intrepid_Explorer]

​@ciontachthecthonicchampion3576 You are not mistaken; emotions are very much real even in wild animals. The reason the cuckoo appears so furious is not out of simple hunger, but because of its instincts. Because the cuckoo has evolved to possess parasitic instincts, it instinctively knows that the birds that raise it are not its actual parents. Thus, unlike the other chicks, the cuckoo's singular impulse is to abuse and annoy the birds that raise it into giving it all the food possible, as it instinctively has no love for them.

[@shirojaki2063]

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.

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.

Everyone calling the cuckoo chick a monster... it's literally a dumb animal incapable of acting on anything other than instinct do you legitimately think it can tell right from wrong. If these were dolphins I could possibly see it being "evil" but dolphins evolved intelligence, not a moral compass.

[@Ashes92Ashes]

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.

[@creepercat8536]

I know right? It’s the only way it knows how to survive

Cuckoo birds don’t care about familial bonds. That’s how they’ve evolved to be parasites in the first place.

It failed to eject the other birds, now it's in a dilemma, that it has to compete with the other chicks. Who give the correct cues for the mother bird feed her real brood, while ignoring the interloper because it lacks the cues to stimulate the mother to feed. That's why the cuckoo chick has to expel all the other chicks, so it's the only one for it to cue the parents to feed it.

[@EyeSeeThruYou]

@@armagedom110games2 no, that's not "smart guys," that's mere speciesiest egotism. A test for "smart guys" is whether a species can adapt to its ecosystem without disturbing and destroying it. Corvids can. Cepholopds can. Cetaceans can. Pachyderms can. All primates can, except one. Psychological evolution lagged behind tool-making ability; the two did not develop in parity. As "morality" is not unique to humans, nor is it universal among humans in its application, it isn't a "measure" conferring any special rights on hominids. Try again. And this time, keep check your hominid ego at the door of historical reality.

[@snappypanda8258]

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.

[@andrewsypniewski3403]

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.

Unfortunately, sometimes in very small nests, like warblers, there would not be enough room for eveyone, and the cuckoo will push the nestmates out, but here it is doing no harm.

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.

[@nugget4yearsago518]

They often draw a comparison with less "cuddly" parasitic animals. Yeah I wouldn't like having fleas and ticks all over me, or a tapeworm in my intestines, I still wouldn't think that they are doing this out of malice or relishing over pain with sick human-like glee instead of simply acting their nature as they were meant to survive. Placing human morals on animals that couldn't care less is stupid.

[@Sliferslacker21]

@@nugget4yearsago518 Exactly. And whether people like it or not, they still play a key role in the environments they live in by helping to regulate wildlife. Everything has a purpose for its existence in nature. Nature is both beautiful and absolutely cruel, and parasitic creatures are still apart of nature. There have even been studies down on this that show parasitic birds can even be beneficial for the entire brood. These people cheering for the death of a baby cuckoo should not even call themselves animal/nature lovers as it is more then clear they only love a certain part of the animal kingdom and nature.

[@l.n.3372]

But knowing that a bird evolved to be a brood parasite efficiently doesn't mean humans have to like it, after all. They have developed an efficient ecological niche, but humans don't have to respect them for it. Most humans watching these videos feel badly for the host birds. Normally, their eggs would be killed by baby cuckoo. It's understandable that the people watching the videos are relieved that mama bird is taking care of her own babies and not the brood parasite. It's true that humans shouldn't apply human logic to animals, but humans cheer for heroes in movies over the villains, too. It's not that unusual that they would see the cuckoo bird as villainous for killing off competition. Is it wrong to apply human mentality to birds? Sure, but it's understandable why people watching feel this way. It doesn't make them psychotic

[@huldu]

That's not how it works sadly. The clips where the mother feeds the cuckoo are edited out, that's one healthy cuckoo if I ever saw one. The mistake this cuckoo did was not getting rid of the eggs(ie the competition). That's normally what they do. The mother can't tell the difference, they all smell the same. That's why cuckoos have been so successful. In some cases the cuckoo can become enormous compared to the bird feeding it. I had a book with cuckoos long ago and there was this funny picture of the mother bird sitting on the cuckoo and feeding it. The cuckoo was like 4-5 times the size of the "mother".
