Do longwings build their own nests?

Longwings, which include species like the peregrine falcon and the merlin, typically do not build their own nests. Instead, they often utilize old nests created by other bird species. This behavior allows them to take advantage of existing structures, which can provide a safer and more efficient nesting site. By using the nests of other birds, longwings save energy and time that would otherwise be spent on nest construction.

Other choices suggest either that they build nests in trees or on the ground, or that they use ledges for nesting. However, while some raptors may use ledges or build nests, longwings specifically are more inclined to repurpose existing nests rather than create their own, making the correct response the one that indicates their reliance on the nests of other species.
