Bare-necked Umbrellabird
The bare-necked umbrellabird (''Cephalopterus glabricollis'') is a species of bird in the family Cotingidae. It is found in the Talamancan montane forests of Costa Rica and Panama. Bare-necked umbrellabirds live only in forests and their diet consists mainly of fruits. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. Taxonomy and systematics The bare-necked umbrellabird is one of three species in the genus '' Cephalopterus'', commonly known as the umbrellabirds. It was first described by John Gould in 1851, on the basis of specimens collected by Warzewickz at elevations of in Panama. The generic name ''Cephalopterus'' comes from the Greek κεφαλη (''kephalē''), meaning head, and πτερος (''pteros''), meaning feathered, referring to the head plumes of the Amazonian umbrellabird. The specific epithet ''glabricollis'' is from the Latin ''glaber'', meaning bald, a ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist who published monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould (illustrator), Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. Because of his 1840s seven-volume series ''The Birds of Australia (Gould), The Birds of Australia'' and its updates he has been considered the father of bird study in Australia, and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life John Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained ...

Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...

Altitudinal Migration
Altitudinal migration is a short-distance animal migration from lower altitudes to higher altitudes and back. Altitudinal migrants change their elevation with the seasons making this form of animal migration seasonal. Altitudinal migration can be most commonly observed in species inhabiting temperate or tropical ecosystems. This behavior is commonly seen among avian species but can also be observed within other vertebrates and some invertebrates. It is commonly thought to happen in response to climate and food availability changes as well as increasingly due to anthropogenic influence. These migrations can occur both during reproductive and non-reproductive seasons. The patterns of altitudinal migration may be affected by climate change resulting in potentially life-threatening situations for some species. Deforestation can affect the migration corridors of altitudinal migrant and could lead to smaller areas for these species to migrate. Changes in the environment of altitudinally ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Primary Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without Disturbance (ecology), disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and Canopy (biology), canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debr ...

Understory
In forestry and ecology, understory (American English), or understorey (English in the Commonwealth of Nations, Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the Canopy (biology), forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy, so understory vegetation is generally Shade tolerance, shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines, and undergrowth. Small trees such as holly and Cornus (genus), dogwood are understory specialists. In Temperate broadleaf and mixed forest, temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the ...

Subcanopy
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted mountaineering gear, has made canopy observation significantl ...
