The cuckoo bird failed. The mother bird pecked the cuckoo egg and threw it out 杜鹃鸟被识破了，鸟妈妈啄破杜鹃蛋，扔出鸟窝

😂😂😂

usually, the cuckoo replaces one egg with its own and not simply add one to the nest. there were likely four reddish eggs before the cuckoo paid a visit

The mother cuckoo is not much of a mother to abandone her egg!😔 Still it's sad.😥

That's funny!!

@@brendaann727… they’re parasitic. They lay eggs in other bird nests so another bird mom has to feed/take care of them.

Yeah but the cuckoo will usually try to fool the host by throwing out one of their own eggs, so there's a cost.

​​@@butmunchass Some have developed the ability to create eggs that closely resemble the ones they parasitize in color and spotting, but they'll be bigger. Hard to believe.

😂😂😂😂 نعم

And for free 🤩

Birddash

that bird was like hey who delivery this meal

That is, assuming the cuckoo's parents didn't see that. Some brood parasites have been known to come back around to check up on their egg or chick from time to time, and vengefully destroy the host's eggs or kill the host's hatched chicks themselves if they find that their egg was destroyed or the resulting chick has died.

​@@TrashJack3000Wow they truly are evil then

​@@13ased_Americansome birds tolerates and feeds the cuckoo chick knowing the fact that the cuckoo parent must be near watching

​@@13ased_AmericanThey're not evil. Just doing what it takes to survive.

@@GenericDan I understand living in another birds nest that's one thing but to push out her real eggs/birds?! That's completely selfish but I understand nature is nature and there's not really cruel in nature just how they adapted to living.

Eggs are full of cholesterol, but they don't raise our cholesterol when we eat them. We used to think they did, but now we know they don't.

Definitely a Republican bird. She has no tolerance for illegals in her nest.

do you know the species of the 'mama bird'? maybe it was the father. is it some sort of magpie?

Just like single mothers trying to cuck nice guys into raising another man's kid.

I don’t know.

@@embreis2257 It may be a bird we call blackcap.

She saved her chicks. Birds don't have babies.

@@kathleenevans1201chicks are baby birds. So yes, they are babies.

@Chiffawndue No, they are not babies. Babies are born to human mothers. Chicks are hatched out of an egg. So, no, chicks are not babies.

@@Chiffawndue Birds are hatched from eggs. Humans are born. Birds are chicks, not babies.

Aren't robins particularly good at spotting fakes? Pretty sure there were studies where a nearly identical egg was placed in a nest and the mother found it immediately. Might not have been robins though.

Or has someone just put it in for the sake of a video...I doubt very much that was the egg of a cuckoo.

People torture turtles faking rescue videos. You think nobody would put a egg like this for views?

That’s kinda cool!

@@BeasleyStreetThat’s exactly what I was thinking

Sadly it usually works since most Birds are mind-meltingly stupid. Even when the Cuckoo hatches and grows to be bigger than the Parents, most Birds do not suspect a thing.

Exelente ,felicitaciones al Pajaro que reconoce que no es suyo.

You're a parent bird? xD

And the parent bird got some nourishment, good deal! Here's hoping the cuckoos do not return. 😊

​@@nyancat8828 some seem to think they are, bestowing all sorts of human reasons, behaviors onto what the birds and chicks are doing

​@@nyancat8828 A bird with an avian adaptive smartphone! And that ain't chicken feed. Haha. 😅

Monkeys nevers craps

Some birds recognize this some don't. The big problem is the cuckoo shoving the eggs, and chicks out of the nest, sometimes with parent bird watching it happen, being puzzled, doing nothing. The cuckoo causes such a disruption that brooding ceases because 'the thing' never rests. 'The Thing' 😮

@@ezstreete yes. For some reason bear comes out of eggs with a low possibility.

​@@gx8raympm2zj54i used to call it bear chicks..

And dad. Join the movement to include fathers, as in many breeds, BOTH parents are identical, or close enough to require expert observation. Both brood, feed, and tend nest equally. So let's quit these comments by people who don't know any better and claim mother this and mother that, when half the time it's dad, not mom. Doesn't mean all species, as some deliver to mom. Raptors, totally different, some smaller breeds will have both. One creator in the uk had a male do it all, when the female never returned, and the creator has also gotten others involved in foster parenting, even barn owls! Quite Interesting. So don't be like the uninformed and always go far afield in their ignorance in praising mum for everything good, just short of sainthood, and just enjoy what many have never seen before, that in itself is beyond wonderful.

You know what evolution is, right? Old world cuckoos literally cannot do anything different.

Just like his cousin the red chick one

Thank you!

This bird has a white body. It might be a blackcap.

There is no "evil" in nature

It'd be worse, the Cuckoo chicks usually hatch earlier and are generally larger than the host birds. So they will almost always kill off the other chicks by pushing the other eggs out of the nest.

Okay but in the grand scheme of things all lifeforms that don't simply depend on photosynthesis are parasitic.

Como debe ser asi tendrian que hacer todas las mamas!!!

Also much larger.

巢寄生（Brood parasite），又稱托卵寄生，是某些鳥類將卵產在其他鳥的巢中，由其他鳥（義親）代為孵化和育雛的一種特殊的繁殖行為。 某些昆蟲也有巢寄生行為。

有些巢寄生的鳥類喜歡找與其親緣關係近的鳥作為宿主，比如非洲維達雀亞科的鳥；而另外一些則選擇其它科的與之生活習性大致相近的鳥類為宿主。無論是種間的還是種外，寄主都要選擇與自己孵化期和育雛期相似、雛鳥食性基本相同的宿主。 寄主通常只在宿主巢內產一枚卵，有時也會產下多枚。寄主多是在宿主開始孵卵前產卵，如果宿主的卵已開始孵化，寄主常常會把這些卵吃掉或扔掉，如牛鸝會用喙和爪在宿主卵上打孔，使宿主卵孵化失敗並延長宿主的孵卵時間。寄主產卵的時間往往十分短暫，如斑翅風頭鵑（Clamator jacobinus）在宿主的巢中產一枚卵僅需5秒。

在長期的適應選擇中，寄生卵的大小、顏色、卵斑等特徵都與其特定的宿主相似。多數寄主的卵比非寄生的同類的鳥卵要小，或與宿主的卵大小相近。同種的巢寄生者由於宿主不同，所產卵的斑點、顏色也不同，如不同種群的杜鵑，所產的卵因宿主卵的差異而各有不同。寄主的卵還通常較結實，卵殼較厚。 寄主的雛鳥通常較宿主的雛鳥出殼早，一些巢寄生的雛鳥破殼後便本能地將宿主的卵拱出巢外，還有的如響蜜鴷的雛鳥在頜上長有尖鉤，一出巢就用它把巢內宿主幼鳥殺死。此外寄主鳥生長發育迅速，會占有宿主餵食的大部分。 巢寄生對宿主種群的影響大小不一，除黑頭鴨等少數寄主不會嚴重影響宿主繁殖，多數情況都會使宿主鳥繁殖成效降低。 為了繁衍，宿主鳥也發展出一套反寄生的行為。比如許多雀形目的鳥，對於進入其領地的潛在巢寄生者會予以驅趕。宿主鳥築巢時會選擇更隱秘的地方，離巢時還要對卵加以掩蓋，並儘量減少離巢時間。宿主一旦識別出寄生卵，就將其扔出或棄巢。有研究表明，經常被杜鵑巢寄生的宿主鳥對杜鵑卵的識別能力很強，而沒有杜鵑寄生的地區，如冰島的鳥對杜鵑卵的識別能力就很差。

有大約5個科，80多種鳥有典型的巢寄生行為，數量占全世界鳥類總數的1%。 杜鵑科 大杜鵑是人們熟知的巢寄生者，據統計，它能把卵寄生在125種其他鳥的巢中。 文鳥科 非洲的維達雀亞科全是巢寄生者，每一種的寄主相對穩定，主要是梅花雀科的鳥類。 擬鸝科 南美洲分布的擬鸝科鳥多是巢寄生者，其中褐頭牛鸝能在200多種鳥的窩中產卵。[1] 雁鴨科 黑頭鴨是這一科中唯一的巢寄生者，寄主有其它雁鴨科、秧雞、䴉類、鷺類的鳥 響蜜鴷科 這一科的鳥主要生活在非洲撒哈拉沙漠以南的地區及亞洲的熱帶雨林中，全部為巢寄生鳥。

剛出世的布穀鳥會依靠不同的「卑鄙手段」以確保它們就獲得最優質的營養。 1, 比起一般的鳥類更早長出尖嘴，在鳥巢中四處擺動它尖銳的嘴巴，傷害其他鳥蛋或雛鳥。 2, 它們會將其他同巢未出生的「兄弟姊妹」(其他鳥蛋)推出巢外，集中父母的注意力及營養。 3, 在「養母」帶著食物回來的時候，它會用最響亮的叫聲不停大叫以示餓意 但其背後的意義是「你需要優先給我食物，如否我的聲音將吸引其他捕食者過來！」以上的內容都係由書本「自私的基因」入面有提及到， 當然，我們不能以人類的道德倫理量度動物世界的平衡及生態， 弱肉強食是大自然的不二法則， 有的動物靠的是明刀明槍，有的動物是靠團體生活， 有的動物則像杜鵑鳥一樣，靠的是「輕資產」，將養育下一代的責任轉嫁給其他人。雖然布穀鳥的生存方式相當於一個無賴「四處留種，不擔起父母的責任，損人利己」 然而對於農夫來說，它是一個很好的朋友， 因為它的主要食糧是害蟲，例如蝗蟲、松毛蟲、松針枯葉蛾等對農作品有害的害蟲
