"Bad" fathers and mothers in the animal kingdom

Primate, house sparrow, bird … are “parents” ready to throw, kill their young or other species.

Animals that want to survive in nature for a long time have to adapt to a life full of fluctuations and dangers. In order to maintain their lineage, some animals have developed very strange behaviors, they accept the “bad” reputation to survive and thrive at best …
Let’s take a look at a few “bad” fathers and mothers in the animal kingdom through the list on the Mentafloss site.
1. Primate (ring-tailed lemur, gray langur): kills a small child
The primate is one of the most evolved in the animal kingdom. The breeding and parenting of primate groups is also more advanced than other animals. However, there are still many primates who act in very strange, brutal ways – killing their little children without mercy.

In the gray langur, there are instances when the single adult male “friends” in a gang specializing in gambling with other families. They often hunt the “father” first, then “self-driving” within the group to choose the stronger man – having the right to mate with the “mother”. The male who wins this battle will kill the offspring of the family to rebuild a new nest.

Baboons – one of the primates with a habit of killing children.
Eliminating lactating offspring from “new fathers” will cause langur to return to heat and increase strength to mate. With the baboons of the Old Continent, if the mother is pregnant, the “stepfather” does not need to act, because the monkey mother will withdraw her own baby through a miscarriage.
According to a research group at the University of Michigan (USA) to do this, the mother’s body after receiving the signal to have a “new husband” will secrete special hormones to destroy the pregnancy and then heat up. come back to be able to mate as soon as possible.

Babies are always safely surrounded by their parents until another male joins the herd.
Although this behavior is somewhat barbaric, it has very important ecological significance. Killing their own offspring will help them regulate population density and can also be considered natural selection to create offspring with greater vitality and better genetic resources.
2. Cuckoo family: sloths raise children, lay eggs in nests of other birds
It is a very lazy family of birds for raising children. Most species of this family of birds (warbler, yellow beak, etc.) have the phenomenon of nests, that is to say, they lay eggs in the nests of other birds.

But this “laziness” is also the “wisdom” of the birds that give birth. This action gives them more time to feed and reproduce while their offspring have a higher survival rate in the face of natural threats. However, for birds born on nests it is unlucky, they can be left behind in the evolutionary race.

The parasite’s eggs appear almost identical to those of the “adoptive parents”, so they still carelessly incubate it until they hatch. This egg was saved to hatch a few days before the “real” eggs. Once born, the baby bird will push all biological eggs from the adoptive parents out of the nest to eliminate competition.

Poor adoptive parents always think it is their child, so they take great care of it until the baby bird grows up and flies away. When it is discovered that other birds have secretly inserted their own eggs into the nest and pushed them away, the parents of the parasitic birds will become a real mafia.
They will fly to destroy the nest, beat the young birds to take revenge on the enemy because … they are not raising them for themselves. Although cruel, it is an evolutionary way of adapting these birds to breed and breed very well.
3. House sparrow: killing a “stepson”

House sparrow – angry woman.
The house sparrow is a bird widely distributed in the world. They often nest in houses, on eaves or in walls. During mating season in the spring, males will seek out territory, protect it, and build a beautiful nest to attract females. After being paired with a bird and having children, the male sparrow will “flirt”, looking for a place to start a new family.

Like humans, the female sparrow will be extremely angry and attempt to fight jealousy by finding her husband’s new “digress” and destroying the nest, mercilessly killing her innocent children.

Since she has to keep a group of chicks, the female sparrow needs the support of the male sparrow.
In this way, the male sparrow is forced to spend more time feeding and protecting the old children. Unable to raise a flock of newly hatched offspring on her own, the female sparrow is forced to attack and destroy the offspring “out of wedlock” to increase her own survival. Anyway, it’s also a bit of an “overly” act of this little bird.
4. Water pheasants: Destroy the opponent’s children
Water pheasants are birds of the pheasant family, from the order of chickens. They often live in freshwater ponds, lakes, and swamps for food. In chickens, there is often a distinction between males and females – beautiful males are polygamous, and the reproductive and caring tasks of females are those of females.

But in aquatic pheasants, the opposite is true: the hen lays eggs, but the male is responsible for keeping the eggs until they hatch. The female will go around to protect the territory and take advantage of a few other companions. He continues to mate, lays eggs and is left in the care of the rooster.

The peculiarity is that these mothers of water pheasant have very “wandering” companions, we discovered in the study of Emlem and Demong. In the territory, if he finds out that there is another female nesting, laying or flirting with the “uncontrollable” male, he will immediately organize a “terrorist” during the session. afternoon and night.

The battle between two mothers.

The mother hens will come to war, they will fight one-on-one, the winner will have the “ideal husband” to take care of the children. Without stopping there, the surviving mother will destroy the nest of the vanquished, destroy even innocent young children, even those who have not yet been born.

Not only does not fulfill a mother’s duty to take care of her children and raise her children, but the doing females also become “brothers and sisters” when there are many acts of violence. However, in terms of ecology, it is a very unique way that they have chosen to adapt to life, to survive to this day.
