avian nesting strategies

Avian nesting strategies refer to how birds select, build, and defend their nests to maximize survival for their eggs and chicks. Some species build elaborate structures in trees or on the ground, often choosing locations that offer protection from predators and harsh weather. Others use existing cavities or scraps of materials for concealment. Nesting behaviors vary widely—some birds lay many eggs with less investment per attempt, while others invest heavily in fewer offspring. These strategies are influenced by factors like environment, predator threats, and reproductive needs, ensuring the best chances for raising healthy offspring.
