Impact of Brood Parasitism

Brown-headed Cowbirds are known for laying their eggs in the nests of other bird species, including the Eastern Phoebe. This behavior, known as brood parasitism, poses a significant threat to Phoebe populations as the cowbird chicks often outcompete the Phoebe nestlings for resources. In response to this threat, Eastern Phoebes have been observed to recognize and reject cowbird eggs from their nests, reducing the success of parasitism attempts.

Reproductive Trade-offs

Eastern Phoebes may face trade-offs when allocating resources between multiple broods. Investing energy and time in raising offspring comes with an opportunity cost, potentially impacting their ability to survive and reproduce in subsequent breeding attempts. Understanding these trade-offs is essential for comprehending the long-term reproductive strategies of Eastern Phoebes.
