What kind of song is Swallow?

Thinking of writing: Imitate similar animals according to the structure of egrets in the text.

Swallow is a cheerful song.

The combination of pigments, the size of the body, everything is suitable.

Sparrows are too small and vulgar, even noisy cuckoos or beautiful kingfishers feel too unusual.

However, because it is ordinary, the swallow has forgotten its beauty.

Black and shiny feathers, handsome and brisk wings, scissors-like tail and small gray beak make up a lively and lovely swallow.

In a warm spring, the breeze blows thousands of willow trees. Green grass, green leaves and colorful flowers gather together like a market, forming a dazzling spring. Swallows fly from the south, adding a lot of vitality to spring.

In the vast fields, swallows lean against the sky and sing, and some fly from rice fields here to willow trees there in an instant; Some swept across the lake, and the tip of the tail occasionally touched the water surface, so they saw ripples all around.

On the high telephone pole, several pairs of tired swallows landed on the wire, which looked like a staff! The stopped swallow became a note, a hymn of spring.

Swallows can't sing. But isn't the swallow itself a beautiful song?

Swallow is really a song, a symphony with a light melody!
