When are raptors most likely to desert their nest?

Raptors are most likely to desert their nest just before egg laying. This is a critical time for these birds, as they are establishing their nesting sites and preparing for reproduction. Factors such as environmental disturbances, the presence of predators, and human activity can influence their decision to abandon the nest during this stage. Ensuring a safe environment is paramount for raptors as they select their nesting locations and invest energy into the breeding process.

The other choices represent stages in the nesting cycle where desertion is generally less likely. Right after egg laying, raptors are typically committed to the nesting process and invested in their future offspring. During the incubation period, they generally remain with the eggs to ensure their protection and proper temperature regulation. After chicks hatch, the parents usually remain dedicated to feeding and protecting their young, making abandonment at this stage less common as well.
