在生物课上（笑话，译文）2
译自德语by me， 英语由gemini proofread过
"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."
“哪种鸟不给自己搭窝【1】？” 老师问小克劳斯。
“布谷鸟。”
“你答对了！但是为什么呢？”
“因为它在自鸣钟【2】里生活着。”

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]

杜鹃（布谷鸟）
杜鹃，尤其是许多旧大陆物种，例如大杜鹃，是专性的巢寄生鸟类，它们自己不筑巢。相反，它们会把蛋产在其他鸟类的巢中，由那些鸟类代为孵化和养育幼鸟。这种策略节省了能量，并让雌性杜鹃能够产下更多的蛋。
关于杜鹃繁殖行为的关键事实：
- 巢寄生：雌性杜鹃会在几秒钟内从宿主的巢中移除一枚蛋，并换上自己的蛋，而且通常会模仿宿主蛋的颜色和花纹。
- 宿主选择：它们会针对特定的物种（例如草地鹨、芦苇莺），因为这些鸟类的巢穴类型和取食习性适合养育它们的幼鸟。
- 雏鸟策略：杜鹃雏鸟通常最先孵化，并且会本能地将宿主的蛋或雏鸟推出巢外，以确保自己能独占所有食物。
- 高产蛋量：根据英国皇家鸟类保护协会的数据，一只雌性杜鹃每个繁殖季可以产下12到22枚蛋，并将每一枚蛋放在不同的巢中。
- “黑手党”行为：根据Quora网站上的信息，一些研究表明，如果宿主鸟将杜鹃蛋扔出巢外，成年杜鹃可能会返回并摧毁宿主的巢。
