Heilongjiang residents found a big footprint on the road to nucleic acid. How did this footprint come from?

When Mr. Gao of Harbin Hongxing Forest Farm was crossing a snowfield for nucleic acid detection, he suddenly found a huge animal palm print on the ground and immediately reported the relevant situation to the forest farm leaders. At that time, Mr. Gao was walking in the snow of the forest farm to do nucleic acid testing. On the way, he met a familiar friend. At the same time, they found a very large animal footprint in the snow. Because of the strong contrast between this footprint and human footprints, the first thing that comes to mind is the behemoth. This string of footprints seems to go deep into the forest farm, which shows that this animal is foraging in the snow. There are no large animals in this area, and there are some residential areas around. There are some poultry in the yard.

The administrator of the forest farm carefully measured the size of the footprint and sent it to Heilongjiang Wildlife Research Institute. The relevant staff responded after comparing the size, which is probably an adult Siberian tiger. This news aroused the vigilance of the person in charge of forest farm work. In the snowy Harbin, the only possibility for the Northeast Tiger to run in the snow is foraging. They suspected that it was an animal chasing wild boar. For big cats, although they are at the top of the food chain, the demand in winter forces them to increase the frequency of hunting, which is also an instinct of demand. Because there was no beast like the Northeast Tiger in the forest farm area in the past, people are wondering where this Northeast Tiger came from. The northeast of China is close to Russian. Before, some local animals crossed the border and ran to our area, mostly for foraging, and the ecological environment in the northeast is very good, which is also one of the reasons for attracting exotic animals.

Local administrators in Harbin hurriedly informed the residents around the forest farm that there were footprints of Siberian tigers in the snow nearby, so everyone should pay attention to protection and take good care of poultry when going out. For the hungry Siberian tigers in the severe winter, hunting has become their instinct and first demand. If you are always hungry, the Siberian tiger will be very aggressive. Neighboring residents may also be the target of his attack, while poultry is called an animal that it can easily kill at any time. After learning this news, the local people are still worried about their daily travel. A few years ago, a Siberian tiger from Russia was captured by a tranquilizer gun when it attacked people in Harbin. After a period of inspection, it was returned to its original ecological environment.

Some experts suspect that this Siberian tiger also ran to China from Russia. Animals are very sensitive to changes in the ecological environment, and they yearn for a more natural and better environment.
