* Common choices: Oaks, pines, elms, maples, and sycamores are often used for nesting.
* Important factors: Crows prefer trees with strong branches high up for protection from predators, as well as dense foliage for concealment.
Remember: Crows don't build nests *inside* the tree trunk like some birds. They build their nests in the branches, using twigs, sticks, and other materials.
