Its all they have to use in the wild.
Owls sit up right on trees or sleep in barns.

Alligators usally lay their eggs on the very side of the water with rotten sticks and dirt.
Birds collect sticks and twigs and place them onto a suitable branch (as in a fork) in a branch or the main trunk. They slowly build up on the foundation in a circular fashion, so the outside is higher than the centre. Other birds use mud or even their own spit to harden the nest and stick it all together. Birds use its own spit or mud, and puts the nest together with twigs, grass, pretty much anything it can hold in its mouth. The bid puts the nest in a safe place where predators cannot reach or find. As for Hummingbirds, they make like a big circle with a little hole in the top so they can only get to the egg. Almost all birds have their own system and reasons for building their own kind of nest. Some need or want a specific size material, others will only use a certain type of grass, or will only use hair woven in with small leaves and twigs. Others build only to impress a potential mate, lots of males will work very hard to build the perfect nest to attract a female. So they collect materials, (leaves, twigs, hair, and feathers), then use them to assemble a nest using whatever they have, this is instinct driven by the need to protect their eggs. I could answer with more information i.e. type of bird.
Some birds will use gravel in their nests, but i would search some where else for more specific information.
