Which of the following does not build stick nests?

The true falcons, which belong to the family Falconidae, do not typically build stick nests. Instead, they are known for their preference for nesting in natural cavities, ledges, or utilizing old nests abandoned by other birds, particularly those of larger species. This behavior is partly due to their hunting strategy, which involves catching prey in flight rather than relying on the security of a constructed nest for raising young ones.

In contrast, the other groups mentioned, such as accipiters (like Cooper's and sharp-shinned hawks), buteos (such as red-tailed hawks), and eagles (like the bald eagle), are known to build stick nests. These raptors tend to construct sizable and sturdy nests that are often reused year after year, which is advantageous for raising their young and providing a safe environment. Understanding these nesting behaviors is essential for anyone studying falconry or engaged in wildlife conservation efforts, as it highlights the diversity of nesting strategies among raptor species.
