The Most Disgusting Bird, Which Lays Eggs in Other Birds' Nests, Allowing Other Birds to Raise Its Young!
When people mention birds, many will say that birds are human friends. Birds help humans catch insects, protect trees, and bring people beautiful music. However, there is one type of bird that is an exception, that bird is the cuckoo. In nature, any mother bird that hatches eggs will raise its own children. But the cuckoo is a natural born liar. In order not to raise its own children, it will lay its eggs in the nests of other birds, and then kill the children in the original eggs of other birds. In this way, other birds will wholeheartedly raise his children. The cuckoo is truly a cunning liar and killer in nature.
It's no wonder that there has been the saying of 'occupying someone else's house'. It's because the cuckoo will never build its own nest. What's more mysterious is that even with modern technology, very few people have ever seen the true appearance of the cuckoo. As for its living habits, it's a mysterious existence.
Seeing this, someone might think that the little cuckoo is pitiful, and it is abandoned by its mother as soon as it is born. But the fact is not the case. The little cuckoo has also inherited its mother's killer nature. If it hatches from its shell and finds other little birds or eggs beside it, the little cuckoo will push them out of the nest and let them die. Then the little cuckoo can enjoy food alone. It knows how to eliminate competitors at a young age. Moreover, the little cuckoo is good at deceiving from a young age. Although its size has grown to be bigger than its feeding parents, it can still deceive them and let them continue to feed it until it can become independent.
Why can the little cuckoo successfully deceive its feeding parents? In fact, the cry of the chick at one week old sounds like a whole brood of hungry chicks. When it is two weeks old, it sounds like two broods of chicks are noisy. This is why its feeding parents are deceived. It's just because of love for children.
It's also known that the cuckoo can choose 20 different host species, including Reed Warbler. It's worth noting that not all cuckoos will choose Reed Warbler as a host.
In late April, Reed Warblers migrate from Africa to Cambridgeshire, UK, eventually reaching Wicken Fen. Reed Warblers arrive here to find a mate, build a nest, and feed their young. However, they are always monitored by cuckoos. In Reed Warbler-dense areas, male cuckoos will establish territories, and female cuckoos will come to them soon afterwards.
In mid-May, the earliest Reed Warblers have completed the construction of their nests, which means they will start laying eggs. Meanwhile, the lurking cuckoo is ready to lay eggs at any time. In the distant past, cuckoo ancestors used to build nests. But with the evolution of history, their descendants have become increasingly lazy, and their parental responsibility has become less and less.
