The great spotted woodpecker is a medium-sized woodpecker with pied black and white plumage and a red patch on the lower belly. Males and young birds also have red markings on the neck or head. This species is found across the Palearctic including parts of North Africa. Across most of its range it is resident, but in the north some will migrate if the conifer cone crop fails. Some individuals have a tendency to wander, leading to the recolonisation of Ireland in the first decade of the 21st century and to vagrancy to North America. Great spotted woodpeckers chisel into trees to find food or excavate nest holes, and also drum for contact and territorial advertisement; like other woodpeckers, they have anatomical adaptations to manage the physical stresses from the hammering action. This species is similar to the Syrian woodpecker.
Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specialises in exploiting cacti.
The black woodpecker is a large woodpecker that lives in mature forests across the northern Palearctic. It is the sole representative of its genus in that region. Its range is expanding. The black woodpecker is easily the largest woodpecker species in Europe as well as in the portion of Asia where it lives and is one of the largest species worldwide. This non-migratory species tends to make its home in old-growth forest or large forest stands and excavates a large tree hole to reside in. In turn, several species rely on black woodpeckers to secondarily reside in the holes made in trees by them. This woodpeckers diet consists mostly of carpenter ants. This species is closely related to, and fills the same ecological niche in Europe as, the pileated woodpecker of North America and the lineated woodpecker of South America, also being similar to the white-bellied woodpecker which is distributed to the south somewhat of the black woodpecker in Asia.
The pileated woodpecker is a large, mostly black woodpecker native to North America. An insectivore, it inhabits deciduous forests in eastern North America, the Great Lakes, the boreal forests of Canada, and parts of the Pacific Coast. It is the largest confirmed extant woodpecker species in North America, with the possible exception of the ivory-billed woodpecker, which the U.S. Fish and Wildlife Service has proposed be reclassified as extinct. It is also the third largest extant species of woodpecker in the world, after the great slaty woodpecker and the black woodpecker. "Pileated" refers to the bird's prominent red crest, from the Latin pileatus meaning "capped".
The red-headed woodpecker is a mid-sized woodpecker found in temperate North America. Its breeding habitat is open country across southern Canada and the east-central United States. It is rated as least concern on the International Union for Conservation of Nature (IUCN)'s Red List of Endangered species, having been down-listed from near threatened in 2018.
The downy woodpecker is a species of woodpecker, the smallest in North America. Length ranges from 14 to 18 cm. Downy woodpeckers primarily live in forested areas throughout the United States and Canada, with the exception of deserts in the southwest and the northern tundra. The bird nests in tree cavities and feeds primarily on insects, although it supplements its diet with seeds and berries. The downy woodpecker is very similar in appearance to the hairy woodpecker, although they are not closely related.
The acorn woodpecker is a medium-sized woodpecker with a length of around 20 cm (8 in), and an average weight of 85 g (3.0 oz). It is found across Central America, as well as North into the western United States and South into parts of Colombia.
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 red-naped sapsucker is a medium-sized North American woodpecker. Long thought to be a subspecies of the yellow-bellied sapsucker, it is now known to be a distinct species.
The northern flying squirrel is one of three species of the genus Glaucomys, the only flying squirrels found in North America. They are found in coniferous and mixed coniferous forests across much of Canada, from Alaska to Nova Scotia, and south to the mountains of North Carolina and west to Utah in the United States. They are light brown with pale underparts and grow to a length of 25 to 37 cm. They are proficient gliders but uncoordinated walkers on the ground. They feed on a variety of plant material as well as tree sap, fungi, insects, carrion, bird eggs and nestlings. They mostly breed once a year in a cavity lined with lichen or other soft material. Except when they have young, they change nests frequently, and in winter a number of individuals may huddle together in a shared nest. Unlike most members of their family, flying squirrels are strictly nocturnal.
The eastern screech owl or eastern screech-owl, is a small owl that is relatively common in Eastern North America, from Mexico to Canada. This species resides in most types of woodland habitats across its range, and is relatively adaptable to urban and developed areas compared to other owls. Although it often lives in close proximity to humans, the eastern screech owl frequently avoids detection due to its strictly nocturnal habits.
The Malabar gray hornbill is a hornbill endemic to the Western Ghats and associated hills of southern India. They have a large beak but lack the casque that is prominent in some other hornbill species. They are found mainly in dense forest and around rubber, arecanut or coffee plantations. They move around in pairs or small groups, feeding on figs and other forest fruits. Their loud cackling and laughing call makes them familiar to people living in the region.
The red-cockaded woodpecker is a woodpecker endemic to the southeastern United States. It is a threatened 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.
Lucy's warbler is a small New World warbler found in North America. This species ranges includes southwestern United States and northwestern Mexico. It is one of only two warblers to nest in cavities.
In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches. In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris. Snags provide habitat for a wide variety of wildlife but pose hazards to river navigation. When used in manufacturing, especially in Scandinavia, they are often called dead wood and in Finland, kelo wood.
The fox squirrel, also known as the eastern fox squirrel or Bryant's fox squirrel, is the largest species of tree squirrel native to North America. It is sometimes mistaken for the American red squirrel or eastern gray squirrel in areas where the species co-exist, though they differ in size and coloration.
The Biak paradise kingfisher is a tree kingfisher that is endemic to the Indonesian island of Biak which is one of a small group of islands located in Cenderawasih Bay near the northern coast of Papua. This bird has a turquoise-blue back with a white belly and tail streamers and a reddish beak. Its natural habitat is forests and the IUCN has assessed its conservation status as being "near-threatened".
The moustached kingfisher, also called Bougainville moustached kingfisher, is a species of bird in the family Alcedinidae. It is endemic to Bougainville Island in Papua New Guinea. An estimated 250–1,000 mature individuals are left.
Toucans are Neotropical birds in the family Ramphastidae. The Ramphastidae are most closely related to the Toucan barbets. They are brightly marked and have large, often colorful bills. The family includes five genera and over 40 different species.
