Describe the swallow

The description of the swallow is as follows:

1. The bird's nest is the most beautiful and sturdy of all birds and animals. The grass is fine, and it is firmly stuck with a little mud. The nest is semicircular. Swallows don't want to go to the south for the winter until winter comes.

2. The young couple had straw stalks and clay balls in their mouths, and Qi Xin helped to build a nest. They chase moths, catch caterpillars and share food with swallows with yellow fur and yellow mouths. The bird's nest is never fortified, and it is very happy to accompany the host to enjoy the moon, sip, squeak and laugh.

Swallows know their old masters. Every year when the climate gets warmer, a pair of swallows will return to my old home. The young couple, with straw stalks and mud balls in their mouths, built a small nest together. They chase moths, catch caterpillars and share food with swallows with yellow fur and yellow mouths. The bird's nest is never fortified, and it is very happy to accompany the host to enjoy the moon, sip, squeak and laugh.

The bird's nest is like a half rice bowl, with its mouth open, and it is filled with soft feathers, hay and fine scraps. Swallows sometimes stab the sky like swords; Sometimes it swoops down like a fighter jet group, flying around the stop, echoing from afar.

5. "Whispering-"Who is singing in the quiet forest? You guessed it, it's a swallow flying between the blue sky and white clouds. Probably beside it, there is a beloved swallow. The male swallows sang love songs affectionately, and the beautiful rhyme flowed out like the spring water of the soul. At this time, I think its music is superior to everything in the world. Sure enough, the swallow's mother was moved by its singing. They flew to the sky together and wrote their own Ode to Joy.
