Which factor influences whether raptors will stick with their clutch despite disturbances?

Raptors demonstrate varying levels of nest fidelity and behavioral responses to disturbances based on the developmental stage of their young and the specific timing of their breeding cycle. The laying of eggs represents a critical period for raptors, as they are often committed to incubation and are more protective and less likely to abandon their nest during this phase.

When a raptor is investing effort into incubation, their instinct to protect the developing eggs outweighs other factors such as disturbances from human activity or environmental changes. In contrast, if the young are already fledging or if the clutch is not yet laid, the birds may show different behaviors regarding disturbances. This commitment to their eggs serves as a survival mechanism to ensure that they can successfully raise their offspring, especially during critical developmental phases. Consequently, the decision to stick with the clutch is heavily influenced by the presence and timing of eggs in the nest.
