What do Red-tailed Hawks usually do when their nest tree is climbed by a human?

Red-tailed Hawks typically respond to disturbances at their nest by vocalizing from a distance. This behavior allows them to assess the situation without risking their safety or the safety of their young. By calling out, they can communicate with their mate and potentially deter the intruder without confronting them directly. This method can also serve to alert other nearby hawks and may help in recruiting potential allies if the situation escalates.

When considering the context of their behavior, it is important to note that hawks often prioritize the safety of their nestlings, and confrontation can be too risky. Voicing their distress allows them to remain vigilant and protective while minimizing danger. Other responses, such as attacking or deserting the nest, are less common and would generally only occur if they felt immediate threat to their offspring or if human activity became consistent and intrusive.
