Ferrets also know 'bribery'.

In the meerkat African ferret, the lowly female individuals in the herd are ready to feed their offspring in exchange for not being expelled from the herd.

According to Animal Behavior magazine, the above conclusion is drawn from the data collected in a long study from 1996 - 2011 by British scientists.

The team observed the behavior of 40 groups of meerkat weasels and found that "bribery" behavior often occurs if low-status children have recently lost their children or returned to the herd after being deported.

Kirsty Macleod, a biologist from the University of Cambridge (UK) and a member of the research team, explains, in meerkats, when females dominate pregnancy, they will actively suppress and stop prevent other individuals from reproducing by killing newborns or expelling them.

Specifically, in the last few weeks of pregnancy, they will often find the best way to banish some "stubborn, hardest" objects. In one group, there may be 4 - 5 females with lower status and very strong opposition.

When a weasel is pregnant, it is more likely to kill another female's offspring to try to win and secure care for her children. Therefore, the more well-conceived female weasels eliminate potential competitors.

For meerkats, belonging to a group or group will benefit more individuals, because if they are alone, they are more likely to be killed by carnivores. In many cases, deported female weasels never appear again, so returning to the group or herd is really essential to their survival.

The study authors discovered that breast feeding for the dominant female ferrets is a "bribe" so that the expelled children are allowed to return to the herd, without encountering rejection or any more aggression . They observed that the common behavior of the "bribery" weasels was for the children of the ferret to eat, such as catching scorpions or invertebrates and giving them to the weasel.

Weasels who "exchanged labor for peace" also looked after the ruler of the ruler when they were very young. They have to stay all day in foxes to do the "look-alike" task, which means sacrificing the opportunity to search for food that day.
