Here's everything you never knew about Cuckoos and Brood Parasites.
This video answers all of the following questions:
- What birds lay their eggs in other nests?
- What are Cuckoos?
- Do cuckoo chicks push other chicks out of the nest?
- What are brood parasites?
- Do cuckoos lay their eggs in wren nests?
These questions are answered by examining footage of a cuckoo egg in a wren nest, seeing the cuckoo hatchling push its siblings out of the nest, and then observing how the cuckoo chick vastly outgrows it's adoptive bird mother / host.

"But the one you have to watch out for is the cuckoo bird. Do you know how a cuckoo bird survives? By preying on a mother's weakness. The cuckoo bird is too clever to raise its young. Instead, it sneaks its eggs into the nests of simpler birds. So when they hatch, the mother bird is fooled. She feeds them, nurtures them. And do you know what happens to her own chicks? They starve and die from neglect. All because a mother loved a chick...that wasn't her own." - Shere Khan, _The Jungle Book_ (2016)

[@raiinstraw9323]

too clever to raise its young? i need some more context on this cuckoo bird!

[@theflippantfox]

​@@raiinstraw9323 the cuckoo bird doesn't build a nest as it is too much work.. she likes to be free and fly around without any particular place to call home

This is going to create a arms race for big brain birds.

[@brookepearson]

It's interesting that the baby bird knew from birth to push out the other birds to get more food

[@gravel9270]

It is purely from instinct that they will push anything with their back that evolved to be wider and flatter to better aid their action.

[@Raylen_Fa-ield]

Some parasitic birds are even born with hooks on their beaks to break open the other eggs before they hatch, or to kill the new born once hatches

[@quetzacoatlx]

Those who don't push out other birds didn't survive the evolution.

There is actually some research that shows that the birds who are parsitized know the baby isn't theirs. The reason they choose to take care of the egg is because the cuckoo in this case will destroy the nest anyways so better to take care of it and hope the cuckoo doesn't choose your nest again. They have also shown that the warbler will abandoned their nests, too if a cuckoo is in the area

[@alfacinha9609]

Stockholm syndrome

[@JamieElli]

It depends though. Cuckoos have adapted to lay eggs that blend in with the birds they're parasitizing.

[@kingcosworth2643]

That doesn't make any sense, why would the cuckoo not choose the nest again, because the scam went off without a hitch? Birds don't have Judeo/Christian morality teachings regarding kindness and fairness to others. Doesn't make sense in the least. That mother bird, especially if this is it's first nest would have no idea what it's chick is supposed to look like, instinct is very basic and easy to fool, even in humans. That's why babies suck their thumbs.

[@jayarajs3696]

That's a shitty discovery btw,,by some stupid morons!!

[@and9091]

With respect to those birds, I don't think the birds would think "better take care of it so some other bird doesn't destroy my nest", that doesn't make sense, I think the birds know that the bird in the nest is somewhere different from themselves, but out of nurturing instinct or something like that their will continue to take care of that bird, but they also will choose to nest in a area where that bird isn't exist to increase the survival rate of their eggs.

I hate how your videos abruptly ended with ads, it's like watching something incomplete and it keeps scratching my heart

[@JojobaNutOil]

i already knew it was a brood parasite but ahhh your content is so relaxing to watch i love itttt! good job!

[@DerRevoIuzzer]

In Germany we have a saying about the Cukoo in german he is calles Kuckuck and some children are called "Kuckuckskind" which means cukoo child. So a child snuck into a realtionship from the mother which made the child with someone else and the husband/boyfriend doesn´t know it.

[@reallyman6502]

oh so that's why the word "cuck" is a thing

[@runnethdown]

​@@reallyman6502 Well, in English "cuck" is short for "cuckold", but "cuckold" was derived from "cuckoo" anyway

[@freedomdude5420]

😂🤣😂🤣, Honey is that my kid.

[@anjachan]

korrekt!

[@justsomeguywithawhitebeard5639]

​@@runnethdown Makes no sense though to call the "victim" the cuck when the cuckoo should be the instigator.

[@uberrave3]

This video reminds me of educational programs i watched as a kid. It's very nostalgic, but as an adult, i can tell it's more than that. From my observation, not a single sencond wasn't considered in the making of this video. I wish there were more content creaters that strive to put this level of care in their videos.

[@Donirexian]

The music in the background is amazing! It's so subtle but perfect captures each little reveal/moment/mood in the video. I really like mystery games and this video gave me those kind of vibes, it was very intriguing to watch. I would enjoy watching more videos with this format

[@user-gt5nf1zm6b]

Oh no this is so sad i feel bad for the other babys 😢 but this is nature

[@crawhey]

So are murder hornets. We are too, but I feel the invasive threat of giant foreign insects spreading over a new region in modern times is a better example to illustrate the relevant point of save a baby’s life to save a baby from death.

[@humanaku9135]

this is a great format for a younger audience that doesn't know about Cuckoos and other brood parasites but I like your videos without a "narrative" so to speak.

The saddest part is when the baby bird pushed their sibling..

Dear Mr Odd A.S., I realllly like your varied examples of wonderfull Nature: allways interesting and smart! I hope your channel gets viewed in schools, all ages! My one major request is this: do you have control over your Transcript? Mainly, can your ‘activate’ it? So it can scroll (or better: reader can scroll themselves) for those with hearing restrictions can enjoy your videos like the rest of us. (Or my own reason: i watch, sound off, at work and am sad when i cannot scroll interesting content, like your’s, via transcripts). Cheers!

[@-C.I.A]

Hey! Can you guess what species this is?: The specimen is almost entirely known by its vertebral column (axial skeleton): five cervical vertebrae (including the axis), ten articulated mid-to-posterior dorsal vertebrae, two sacral vertebrae, and six caudal vertebrae (five of which are complete). The only other bones found with the specimen are a complete ilium and two unidentifiable bone fragments. The specimen is preserved partially articulated. However, the overall preservation is poor, with a dark reddish-brown to grey colouration indicative of a haematite coating and permineralization. Additionally, the deformation has distorted the shape of the vertebrae and parts of them have been cracked and weathered away.

[@-C.I.A]

It's a reptillan, part of Synapsid, and belongs to Varanopidae

[@demo8175]

No I'm pretty sure it's a worm.

[@DigiDragon001]

[@YesseniaZelaya-xm8db]

How do you make a collection of insects? And how do you spread a insects wings?

[@spidey0123]

One question though, did “big baby” already know how to do that or it’s just inadvertently since he’s too big? Because I remember watching a scene somewhere where there are 3 chicks being fed and one was humongous (the adopted chick).

[@nyancatismyonlyfrand]

It’s part of their evolution. They instinctively know and have grown to be perfect for pushing the siblings out! They know if they don’t do it they will have less food

[@nomaidens8902]

I heard of this before, so I kind of knew it was going to be about a cuckoo. But the entire process just feels so much more cunning, with the actual babies being pushed out etc.

[@brennanperry8001]

Nature is nuts, man. It makes me wonder though. If that bird is unable to recognize that the cuckoo chick isn't theirs, then what things are we just physically unable to comprehend? What things are just in front of us that we don't even -- can't even recognize because our brains don't work in a way that's able to see them?

[@emmymcc1]

You need a tv show! ❤🎉

[@Dr.IanPlect]

3:58 "simply a pawn in the master plan of the...cuckoo" - A minor point, but one that can be misleading. There's no planning or foresight involved. It's just an example of evolution by natural selection producing a strategy, which has no goal, plan or foresight.

That's absolutely fascinating! It's a whole new layer of survival strategy in the bird world. It's incredible how these birds adapt to the threat of cuckoo parasitism, making calculated decisions to protect their nests and future offspring.
