What are the phenological phenomena of the slight cold solar term? In Yanbei Township, magpies began to build nests and pheasants began to grow.

The slight cold solar term is the 23rd solar term among the 24 solar terms in the lunar calendar, which marks the official start of winter. At this time, the scene of nature began to change gradually, and animals and plants began to prepare for the coming spring. In this season, we can observe some special phenological phenomena, which are unique manifestations of nature in cold winter.

First of all, Yanbei Township is one of the phenological phenomena. At this time, the geese began to migrate north and returned to their breeding grounds in the north. This is a natural migration behavior of geese in winter. They will use the flow of cold air and the earth's magnetic field to navigate and find the most suitable habitat. This migration behavior is not only the adaptive evolution of geese for survival, but also a very spectacular phenomenon in nature.

Secondly, magpie nesting is another phenological phenomenon. At this time, magpies began to build nests in trees and prepare to breed. Magpies are very clever birds. They can build strong nests with branches and other materials to protect their eggs and young birds. The phenomenon that magpies start to build nests not only shows their wisdom and creativity, but also implies that spring is approaching, because spring is the peak of bird breeding.

Finally, the beginning of pheasant is also one of the phenological phenomena of slight cold solar terms. Pheasant is a kind of pheasant. At this time, they began to make courtship calls to attract the opposite sex. The word "pheasant" means "call", so the first call of pheasant is the courtship call of pheasant. This phenomenon shows that with the deepening of winter, nature began to prepare for the arrival of spring.

Generally speaking, the phenology of slight cold solar terms is a unique expression of nature in cold winter. By observing these phenomena, we can better understand the laws and changes of nature and feel the magic and beauty of nature. At the same time, these phenological phenomena also remind us to respect nature, protect the environment and live in harmony with nature.
