Both predators and brood parasites can be major threats to the reproduction of many birds. A new study shows that some cuckoo chicks can help deter nest predators, potentially improving host reproductive success when predation risks are high.
无论是捕食者还是巢寄生者，都可能对许多鸟类的繁殖构成重大威胁。一项新的研究表明，一些杜鹃雏鸟可以帮助阻止巢捕食者，当捕食风险较高时，这可能会提高宿主的繁殖成功率。
