What are the characteristics of swallows in the first rainy season?

The rainy season coincides with the season of the northeast monsoon. Rain is abundant, everything begins to grow, the humid environment is very suitable for the growth of insects, insects are one of the main food of swiftlets, so the food of swallows is guaranteed, the salivary glands are more developed, and the saliva secretion is more, during this period, the swiftlet saliva system is active, the bird's nest is relatively full and thick, and the nesting speed of swiftlets becomes faster, preventing the bird's nest from oxidizing and turning yellow, and the bird's nest color of the bird's nest in the first rainy season will be more white.

There are also strong winds and low temperatures in the rainy season, so the feathers of swiftlet's nest are relatively strong and not easy to fall off, and it is not the time to change moults, so the bird's nest will be cleaner in the first rainy season, and the bird's nest content is less, and most of them are very light bird's nests, and the purity of bird's nests will be higher.

What is the difference between rainy season bird's nest and dry season bird's nest.

The main differences between rainy season bird's nest and dry season bird's nest in the first season are as follows:

1.Color; In the rainy season, swiftlets have abundant food, salivary glands will be more developed, and the humidity of the air will make the bird's nest color whiter, while in the dry season, nesting will be relatively difficult, and the color will be a little yellower.

2.Impurity; The moulting period of swiftlets is in the dry season, so there will be more bird's feathers and other impurities in the bird's nest in the dry season, and the bird's nest will be cleaner in the rainy season.

3.fullness; During the dry season, the activity of insects decreases, resulting in a decrease in the saliva content of swiftlets, resulting in thinner nests and fuller nests during the rainy season. The appearance and cleanliness of bird's nests in the first rainy season are better than those of bird's nests in other seasons.

A: The first swallows in the rainy season are the first swallows in the bird's nest in the rainy season, because the cool rainy season will bring abundant food, sufficient rain, and natural conditions such as sunlight, which is still very beneficial to the growth environment of swallows. So they grow very well, too.

The first swallows born during the spring rainy season are called the first swallows. The first swallows born have a short growth cycle and are greatly affected by the season, so they fly away before the rainy season.

The rainy season first swallow mainly comes from some Southeast Asian countries and refers to the first swallow that is harvested in January. Because of the influence of the environment, the swallow will be whiter, cleaner and fuller in the first rainy season, and correspondingly, it will be more expensive.
