在生物課上（笑話，譯文）2
譯自德語by me， 英語由gemini proofread過
"Which bird does not build its own nest?" the teacher asks little Klaus.
"The cuckoo."
"Correct! And why not?"
"Because it lives in a clock."
“哪種鳥不給自己搭窩【1】？” 老師問小克勞斯。
“布穀鳥。”
“你答對了！但是為什麽呢？”
“因為它在自鳴鍾【2】裏生活著。”

Cuckoos, specifically many Old World species like the Common Cuckoo, are obligate brood parasites that do not build nests. Instead, they lay their eggs in the nests of other bird species, which then hatch and raise the young. This strategy conserves energy and allows the female to lay many eggs. [1, 2, 3, 4, 5, 6]
Key Facts About Cuckoo Breeding Behavior:
- Brood Parasitism: Females remove one egg from a host nest and replace it with their own within seconds, often mimicking the host egg's color and pattern.
- Host Selection: They target specific species (e.g., meadow pipits, reed warblers) whose nest types and feeding habits suit their young.
- Hatchling Tactics: The cuckoo chick usually hatches first and, instinctively, pushes the host's eggs or hatchlings out of the nest to secure all food for itself.
- High Output: A female cuckoo can lay 12 to 22 eggs per season, placing each in a different nest, according to the RSPB.
- The "Mafia" Aspect: Some studies suggest that if a host bird ejects the cuckoo egg, the adult cuckoos may return to destroy the host's nest, according to Quora. [1, 2, 3, 4, 5, 6]

杜鵑（布穀鳥）
杜鵑，尤其是許多舊大陸物種，例如大杜鵑，是專性的巢寄生鳥類，它們自己不築巢。相反，它們會把蛋產在其他鳥類的巢中，由那些鳥類代為孵化和養育幼鳥。這種策略節省了能量，並讓雌性杜鵑能夠產下更多的蛋。
關於杜鵑繁殖行為的關鍵事實：
- 巢寄生：雌性杜鵑會在幾秒鍾內從宿主的巢中移除一枚蛋，並換上自己的蛋，而且通常會模仿宿主蛋的顏色和花紋。
- 宿主選擇：它們會針對特定的物種（例如草地鷚、蘆葦鶯），因為這些鳥類的巢穴類型和取食習性適合養育它們的幼鳥。
- 雛鳥策略：杜鵑雛鳥通常最先孵化，並且會本能地將宿主的蛋或雛鳥推出巢外，以確保自己能獨占所有食物。
- 高產蛋量：根據英國皇家鳥類保護協會的數據，一隻雌性杜鵑每個繁殖季可以產下12到22枚蛋，並將每一枚蛋放在不同的巢中。
- “黑手黨”行為：根據Quora網站上的信息，一些研究表明，如果宿主鳥將杜鵑蛋扔出巢外，成年杜鵑可能會返回並摧毀宿主的巢。
