In fact, owls have been regarded as "ominous birds" since ancient times, and they are also called "mourning birds" and soul-chasing birds among the people. In ancient books, night owls are also called strange owls, ghosts and wanderers as a symbol of bad luck and death. This is really not a feudal superstition, and the accuracy is really high. It is also for this reason that many old people are afraid of night owls, let alone joking.
Owl's laughter can predict people's death in advance because owl's sense of smell is very sensitive. The human body itself is an electrolyte composed of acid, alkali and salt. When the human body is about to die, the electrolyte accelerates its decomposition, that is, the decomposition speed of metabolism is much faster than the synthesis speed.
At this time, it will emit a smell, which is the smell of carrion. When owls smell this smell, they will fly to look for food. When it can smell the food but can't find the meat, it will make an anxious cry, which is what the folks call the owl's laughter.
Every old saying summed up by the ancients has been observed and summarized a lot. The ancients found that whenever night owls gave strange smiles, they usually died, so they summed up this proverb and thought owls were unlucky birds.
Living habits of owls:
Owls mostly inhabit trees, and some species inhabit rocks and grasslands. The vast majority of owls are Nocturnal Animals. They lie down during the day and go out at night. It is not easy to see them in the caves or eaves of trees during the day, but some species, such as spotted snipe, striped owl and carved owl, are restless and lonely during the day and often go out for activities. Species that have been active at night, once active during the day, tend to fly around like drunkards.
Owls mainly eat mice, but also insects, birds, lizards, fish and other animals. They all have the habit of spitting "food pills" and have digestive ability. Food is often swallowed whole. The indigestible bones, feathers, hair, chitin and other residues in food are integrated into small balls and spit out through the esophagus and mouth, which is called food pills, also called saliva. Scientists can know their eating habits according to the analysis of edible pills.
