Knowra Nest box Nest box A human-made enclosure that provides a cavity for animals to nest, roost, or shelter. Designs vary with the species and habitat they are intended to serve.
Entrance hole : An opening through which an animal enters and leaves an enclosure. Its size can admit target species while excluding larger competitors or predators.
Bluebird trail : A managed series of nest boxes designed to provide breeding sites for bluebirds. It shows how repeated boxes and maintenance can support a cavity-nesting bird population.
Nest-site competition : Competition among animals for limited places to nest or reproduce. A box can become a contested resource, including among species it was not meant to attract.
Tree hollow : A cavity in a tree that can provide shelter or a nesting site for animals. It is the natural cavity most commonly imitated by a nest box.
Nest box dimensions : The internal measurements and entrance size of an artificial nesting cavity. Cavity dimensions influence which species can use a box and how safely they nest.
Bat box : An artificial roost designed to provide shelter for bats. Its narrow chambers adapt the cavity-box idea to bats' roosting needs.
Cavity-nesting bird : A bird that nests in a hole or enclosed cavity in a tree, rock, building, or similar structure. Nest boxes imitate cavities used by this broad group of birds.
Nest : A structure or site used by an animal for laying eggs, raising young, or resting. A nest box is a human-provided site, while nests include many forms and locations.
Nest box placement : The choice of location, height, orientation, and spacing for an artificial nesting cavity. Placement affects access, exposure, predation risk, and competition.
Bee hotel : A structure containing cavities or tunnels intended as nesting sites for solitary bees and other insects. It extends artificial cavity provision beyond birds and mammals.
