‘Bird’s nest’ (niǎo cháo) is a compound noun formed by combining 鸟 (niǎo), meaning ‘bird’, and 巢 (cháo), meaning ‘nest’. Literally, it refers to the structure birds build—often from twigs, grass, or mud—to lay eggs and raise their young. In nature, bird nests vary widely in shape, size, and location depending on species and environment.

Beyond its literal meaning, 鸟巢 is also widely recognized as the nickname for the Beijing National Stadium, built for the 2008 Summer Olympics, due to its distinctive woven steel exterior resembling a giant bird’s nest. This dual usage makes the term culturally rich: it appears in biology textbooks, nature documentaries, children’s stories, and architectural discussions alike—always evoking ideas of shelter, home, craftsmanship, and natural ingenuity.
