A nest box, also spelled nestbox, is a man-made enclosure provided for animals to nest in. Nest boxes are most frequently utilized for birds, in which case they are also called birdhouses or a birdbox/bird box, but some mammals such as bats may also use them. Placing nestboxes or roosting boxes may also be used to help maintain populations of particular species in an area. [1]
Nest boxes were used since Roman times to capture birds for meat. The use of nest boxes for other purposes began in the mid-18th century, and naturalist August von Berlepsch was the first to produce nest boxes on a commercial scale. [2]
Nest boxes are getting more attention because increasing industrialization, urban growth, modern construction methods, deforestation and other human activities since the mid-20th century have caused severe declines in birds' natural habitats, introducing hurdles to breeding. Nest boxes can help prevent bird extinction, [3] as it was shown in the case of scarlet macaws in the Peruvian Amazon. [1]
Nest boxes are usually wooden, although the purple martin will nest in metal. [4] [ unreliable source? ] Some boxes are made from a mixture of wood and concrete, called woodcrete. [5] Ceramic and plastic nestboxes are not suitable. [6]
Nest boxes should be made from untreated wood with an overhanging, sloped roof, a recessed floor, drainage and ventilation holes, a way to access the interior for monitoring and cleaning, and have no outside perches which could assist predators. [7] Boxes may either have an entrance hole or be open-fronted. [8] Some nest boxes can be highly decorated and complex, sometimes mimicking human houses or other structures. They may also contain nest box cameras so that use of, and activity within, the box can be monitored. [9]
The diameter of the opening in a nest-box has a very strong influence on the species of birds that will use the box. Many small birds select boxes with a hole only just large enough for an adult bird to pass through. This may be an adaptation to prevent other birds from raiding it. In European countries, an opening of 2.5 cm in diameter will attract Poecile palustris , Poecile montanus ; an opening of 2.8 cm in diameter will attract Ficedula hypoleuca , and an opening of 3 cm in diameter will attract Parus major , Passer montanus , an opening of 3.2 cm in diameter will attract Passer domesticus . [10]
The size of the nest box also affects the bird species likely to use the box. Very small boxes attract wrens and treecreepers and very large ones may attract ducks and owls. Seasonally removing old nest material and parasites is important if they are to be successfully re-used.
The material used in the construction may also be significant. Sparrows have been shown to prefer woodcrete boxes rather than wooden ones. Birds nesting in woodcrete sites had earlier clutches, a shorter incubation period, and more reproductive success, perhaps because the synthetic nests were warmer than their wooden counterparts. [11]
Placement of the nest box is also significant. Some birds (including birds of prey [12] [13] ) prefer their nest box to be at a particular height, while others (such as ducks) may prefer them to be very low or even at ground level. Orientation relative to the sun is also important, with many birds preferring their boxes to be away from direct sun and sheltered from the prevailing rain. [14]
Bat boxes differ from bird nest-boxes in typical design, with the larger opening on the underside of the box, and are more often referred to as bat boxes, although in regard to the rearing of young, they serve the same purpose. Some threatened bat species can be locally supported with the provision of appropriately placed bat-boxes; however, species that roost in foliage or large cavities will not use bat boxes. Bat boxes are typically made out of wood, and there are several designs for boxes with single or multiple chambers. Directions for making the open bottom bat houses for small and large colonies, [15] [16] as well as locations to purchase them are available on the internet. [17] Colour and placement is important to ensuring that bat boxes are used; bat boxes that are too shaded will not heat up enough to attract a maternity colony of bats. Australian bat box projects have been running for over 12 years in particular at the Organ Pipes National Park. Currently there are 42 roost boxes using the "Stebbings Design" which have peaked at 280 bats roosting in them. The biggest problem with roosting boxes of any kind is the ongoing maintenance; problems include boxes falling down, wood deteriorating, and pests such as ants, the occasional rat, possums, and spiders. [18]
Nest boxes are marketed not only for birds, but also for butterflies [19] [20] and mammals, especially arboreal ones such as squirrels and opossums. Depending on the animal, these boxes may be used for roosting, breeding, or both, or, as in the case with butterflies, hibernation. [20]
Wasps, bumble-bees, or other insects may build their nests inside a nest box intended for other animals, and may exclude the intended species. [21]
The yellow-billed magpie(Pica nuttalli), also known as the California magpie, is a large corvid that inhabits California's Central Valley and the adjacent chaparral foothills and mountains. Apart from its having a yellow bill and a yellow streak around the eye, it is virtually identical to the black-billed magpie (Pica hudsonia) found in much of the rest of North America. The scientific name commemorates the English naturalist Thomas Nuttall.
The Eurasian tree sparrow is a passerine bird in the sparrow family with a rich chestnut crown and nape and a black patch on each pure white cheek. The sexes are similarly plumaged, and young birds are a duller version of the adult. This sparrow breeds over most of temperate Eurasia and Southeast Asia, where it is known as the tree sparrow, and it has been introduced elsewhere including the United States, where it is known as the Eurasian tree sparrow or German sparrow to differentiate it from the native unrelated American tree sparrow. Although several subspecies are recognised, the appearance of this bird varies little across its extensive range.
The sand martin, also known as the bank swallow, collared sand martin, or common sand martin, is a migratory passerine bird in the swallow family. It has a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries and across the Palearctic to the Pacific Ocean. It is a Holarctic species also found in North America. It winters in eastern and southern Africa, South America, and the Indian Subcontinent.
The glossy ibis is a water bird in the order Pelecaniformes and the ibis and spoonbill family Threskiornithidae. The scientific name derives from Ancient Greek plegados and Latin, falcis, both meaning "sickle" and referring to the distinctive shape of the bill.
The barn owl is the most widely distributed species of owl in the world and one of the most widespread of all species of birds, living almost everywhere except for polar and desert regions, Asia north of the Himalayas, some Indonesian islands and some Pacific Islands. It is also known as the common barn owl, to distinguish it from the other species in its family, Tytonidae, which forms one of the two main lineages of living owls, the other being the typical owls.
The bluebirds are a North American group of medium-sized, mostly insectivorous or omnivorous birds in the order of Passerines in the genus Sialia of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas.
The willow tit is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and across the Palearctic. The plumage is grey-brown and off-white with a black cap and bib. It is more of a conifer specialist than the closely related marsh tit, which explains it breeding much further north. It is resident, and most birds do not migrate.
The red-bellied woodpecker is a medium-sized woodpecker of the family Picidae. It breeds mainly in the eastern United States, ranging as far south as Florida and as far north as Canada. Though it has a vivid orange-red crown and nape it is not to be confused with the red-headed woodpecker, a separate species of woodpecker in the same genus with an entirely red head and neck that sports a solid black back and white belly. The red-bellied earns its name from the pale reddish tint on its lower underside.
The roseate tern is a species of tern in the family Laridae. The genus name Sterna is derived from Old English "stearn", "tern", and the specific dougallii refers to Scottish physician and collector Dr Peter McDougall (1777–1814). "Roseate" refers to the bird's pink breast in breeding plumage.
The white-breasted nuthatch is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 cm (6.1 in) in length. Coloration varies somewhat along the species' range, but the upperparts are light blue-gray, with a black crown and nape in males, while females have a dark gray crown. The underparts are whitish, with a reddish tinge on the lower abdomen. Despite not being closely related, the white-breasted nuthatch and the white wagtail are very similar in plumage. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a wide range of arthropods, but in winter its diet consists mainly of seeds. The nest is located in the cavity of a tree. The clutch consists of five to nine eggs, incubated for two weeks by the female, who is fed by the male. The two adults then feed the young until they fledge, and for a few weeks after that.
The black-capped chickadee is a small, nonmigratory, North American passerine bird that lives in deciduous and mixed forests. It is a member of the Paridae family, also known as tits. It has a distinct black cap on its head, a black bib underneath, and white cheeks. It has a white belly, buff sides, and grey wings, back, and tail. The bird is well known for its vocalizations, including its fee-bee call and its chick-a-dee-dee-dee call, from which it derives its name.
The boreal chickadee is a small passerine songbird in the tit family Paridae. It is found in the boreal forests of Alaska, Canada and the northern United States and remains within this range all year. This bird is known for its high pitched trill patterns used in communication with other birds and food storage habits in preparation for winter months.
The common myna or Indian myna, sometimes spelled mynah, is a bird in the family Sturnidae, native to Asia. An omnivorous open woodland bird with a strong territorial instinct, the common myna has adapted extremely well to urban environments.
The red-cockaded woodpecker is a woodpecker endemic to the southeastern United States. It is a federally endangered species under the Endangered Species Act of 1973.
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere 2 cm (0.8 in) across and 2–3 cm (0.8–1.2 in) high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than 11 m (36 ft) in diameter and stand nearly 5 m (16 ft) tall. The study of birds' nests is known as caliology.
The mountain chickadee is a small songbird, a passerine bird in the tit family Paridae.
The oak titmouse is a passerine bird in the tit family Paridae. The American Ornithologists' Union split the plain titmouse into the oak titmouse and the juniper titmouse in 1996, due to distinct differences in song, preferred habitat, and genetic makeup.
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non-neornithine birds (Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania.
The purple martin is a passerine bird in the swallow family Hirundinidae. It is the largest swallow in North America. Despite its name, the purple martin is not truly purple. The dark blackish-blue feathers have an iridescent sheen caused by the diffraction of incident light giving them a bright blue to navy blue or deep purple appearance. In some light, they may even appear green in color.
The American barn owl is usually considered a subspecies group and together with the western barn owl group, the eastern barn owl group, and sometimes the Andaman masked owl, make up the barn owl, cosmopolitan in range. The barn owl is recognized by most taxonomic authorities. A few separate them into distinct species, as is done here. The American barn owl is native to North and South America, and has been introduced to Hawaii.
