A good paragraph describing the appearance of swallows

Black feathers, smooth and beautiful, extremely smart, plus a pair of scissors-like tails and a pair of agile wings, make up such a lovely and lively swallow.

In February and March, the wind blew gently, and it began to rain in Mao Mao for no reason. Thousands of soft willows relaxed their yellow-green eyes, red, white and yellow flowers, green grass and leaves all rushed to the market, forming a brilliant spring. Those little swallows, so lovely, so lovely, are also composed of adding this beautiful picture of spring, which adds a lot of interest to spring. Swallows with scissor-like tails are flying obliquely in the extremely bright sky in the breeze and drizzle, or when the sun is everywhere. The clear sound has flown from the rice fields here to the sorghum over there. The same birds skimmed the rippling lake, Xiaoyan's tail or wing tip occasionally touched the water surface, and the small halo circles rippled away.

There are several couples who are tired of flying over there, lazily resting on the slender wires. -In the tender blue spring, several wooden poles and traces of several thin lines are connected between poles. There are several thick and small black spots on the line, which are swallows. What an interesting picture! There are also happy families, specially prepared a nest and two nests for our swallows, which are placed at the top of the beam of the main room. If this family has a plaque, it is the best nest for swallows. In the first year, the swallow came and went, and in the second year, our swallow, the couple from last year, will come to live.
