  Endemism in birds - Wikipedia, the free encyclopedia
It would not be incorrect to refer to all bird species as endemic to Earth; in practice, however, the largest areas for which the term is in common use are countries (e.g.
Endemism is particularly notable when not just a particular species is confined to given areas, but a whole higher-level taxon (e.g.

 Ecosystem Profile: Eastern Himalayas Region
The pygmy hog (Sus salvinus) and hispid hare (Caprolagus hispidus) are restricted to the alluvial grasslands and the Namdapha flying squirrel (Biswamoyopterus biswasi) is restricted to the temperate broadleaf forests of the Eastern Himalayas Region.
Endemism among birds in the region is higher than among mammals.
Many of the birds in these forests are not found at comparable elevations in Nepal, where the broadleaf forests are highly fragmented; most likely a result of fragmentation that prevents movements and distribution (Carol Inskipp, pers comm).

Although the populations of forest birds are prone to fluctuations from year to year and cycle to cycle the general trend of the population levels and changes in Hawai'i are fairly consistent, and on the whole are a downward trend.
Birds which were bred in captivity were released at the end of the 1990's and shortly afterwards captive-raised pairs were seen nest building, and some wandered further afield and paired with wild-born individuals.
Although birds are kept in a captive breeding program the species nests rarely in captivity, apparently due to the old age of the birds in the population.

 Report On The Activities
Pine groves are considered not to be as attractive to birds as those of eucalyptus due to its structure which precludes the provision of nesting sites and the fact that few species feed on the seeds in the cones.
The birds may be using the plantations as corridors to pass from one area to another oor may be feeding on flowering species adjacent to the plantations.
In the scrubby open areas, birds which consume nectar and insects appeared to have better feeding conditions through a better availability of light and because the more open the area, the easier it is to catch insects.

These are quail thrushes, really gorgeous little birds that run around on the ground and live in Australia.
Areas of endemism are simply areas that house a number of species that are found there and nowhere else.
For example Tasmania has a group of species of birds that are found nowhere else but in Tasmania, and the same is true for the Atherton Plateau, Cape York, Arnhemland, Kimberley Plateau and on and on.

Birds are one of the best-researched taxa in India and a fairly reliable indicator of biodiversity loss.
Some bird species are not well protected by the IBA approach (such as large raptors, cranes and bustards, which are dispersed at low densities across wide areas and nomadic species).
Bird species can be conserved by protection of sites, and by choosing the richest sites we can conserve many species at the same time, this also makes the best use of the scarce resources that are available for conservation.

Characterized by tropical dry forest, the region is home to approximately 800 bird species, and has one of the highest rates of endemism, especially among birds, in the Western Hemisphere.
The exact number of birds surviving in the wild is unknown, but it is thought to be fewer than 200 individuals.
The goal is to reintroduce 10 birds annually to establish new guan populations with the hope that they will expand and connect with other relict populations in adjacent valleys.

The birds that occur regularly on passage form a large percentage of the ‘Cyprus list’ that currently stands at over 370 species.
Isolation from land masses is one of the factors that produces endemism and a species that is defined as endemic is native to and confined to a certain country or region (of whatever size).
Cyprus has two recognised endemic bird species and at least four endemic sub-species, meaning that these are either found or breed only in Cyprus and nowhere else in the world.

 Drift Seeds and Drift Fruits
If dispersal by birds and air currents are ruled out, it appears that seeds were carried thousands of miles to these islands, possibly by rafting or within protective capsules and pods.
Taking into account all methods of dispersal, including transport by wind, birds, and drifting on the ocean surface, Duncan Porter, a botanist at Virginia Polytechnic Institute and State University, estimates that 378 original introductions could account for the 522 indigenous plant species known to grow on the islands.
Of these natural introductions, 59% were a result of transport by birds, 32% by wind transport, and 9% by drifting on the ocean surface.

 Biogeography - EvoWiki   (Site not responding. Last check: 2007-10-12)
A step away from Biblical literalism was taken in the middle of the eighteenth century by G.L.L Buffon, who proposed that the continents and islands had had several "centers of creation", where their inhabitants' ancestors had been created.
This successfully solved the biogeographical puzzles, though the number of centers of creation had to be large to accommodate oceanic islands, with their high rates of endemism (proportion of species found nowhere else).
Charles Darwin considered the conundrum of oceanic-island species, and he concluded that these were species whose ancestors could have traveled to those islands without much trouble.

 Solomon Islands Student Programs
Lying east of the massive island of New Guinea, the Solomon Islands are comprised of a string of large geologically complex islands shrouded in rich tropical forests.
Although nearly every animal group studied in any depth in the Solomons (which is remarkably few) has revealed striking patterns of endemism, the birds of the Solomons have made the region famous around the world.
The idea of our ongoing biodiversity research program is this: Just as revisiting the Galapagos Islands has broadly influenced understanding of natural selection, re-evaluating bird diversity in the Solomons may alter understanding of two fundamental issues in natural science – the genesis of biological diversity and its long-term conservation.

As witnessed by the rise and fall of the civilizations in Mesopotamia (the Euphrates and Tigris basin) and the Indus basin, it is not possible to sustain supplies of water for life downstream, or to prevent recurrent floods and famines, if the need to nurture the mountain environment is ignored.
Many mountains are functional islands and harbour high endemism, which is of special significance for food security the world over.
They are also home to the rare Cochabamba mountain finch, a bird that only occurs between 3 000 and 4 000 m in northern Bolivia (Hjarsen, 1997).
