Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° to 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal Species The species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes. However, despite not being as biodiverse as tropical systems, this area has a variety of species. Boreal ecosystems are filled with a multitude of flora specie ...

Coccyzus Erythropthalmus
The black-billed cuckoo (''Coccyzus erythropthalmus'') is a New World species in the Cuculidae (cuckoo) family. The scientific name is from Ancient Greek. The genus name, ''kokkuzo'', means to call like a common cuckoo, and ''erythropthalmus'' is from ''eruthros'', "red" and ''ophthalmos'', "eye". It is very similar and overlaps in range with the closely related yellow-billed cuckoo. A distinguishing characteristic of family Cuculidae is laying eggs in the nests of other birds. Although many cuckoos are obligate brood parasites, ''C. erythropthalmus'' often incubate their own chicks.Sealy SG. (2003). Laying times and a case of conspecific nest parasitism in the Black-billed Cuckoo. ''Journal of Field Ornithology''. 74(3): 257–260.

Buteo Platypterus
The broad-winged hawk (''Buteo platypterus'') is a medium-sized hawk of the genus ''Buteo''. During the summer, some subspecies are distributed over eastern North America, as far west as British Columbia and Texas; they then migrate south to winter in the Neotropics from Mexico south to southern Brazil. Other subspecies are all-year residents on Caribbean islands. As in most raptors, females are slightly larger than males. Broad-winged hawks' wings are relatively short and broad with a tapered, somewhat pointed appearance. The two types of coloration are a dark morph with fewer white areas and a light morph that is more pale overall. Although the broad-winged hawk's numbers are relatively stable, populations are declining in some parts of its breeding range because of forest fragmentation. Description The broad-winged hawk is a relatively small ''Buteo'', with a body size from in length and weighing . The tail is relatively short, measuring in length. The tarsus measures fro ...

Aegolius Acadicus
The northern saw-whet owl (''Aegolius acadicus'') is a species of small owl in the family Strigidae. The species is native to North America. Saw-whet owls of the genus ''Aegolius'' are some of the smallest owl species in North America. They can be found in dense thickets, often at eye level, although they can also be found some up. Saw-whets are often in danger of being preyed upon by larger birds of prey. The northern saw-whet owl is a migratory bird without any strict pattern. Taxonomy The northern saw-whet owl was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the other owls in the genus ''Strix'' and coined the binomial name ''Strix acadicus''. Gmelin based his description on the "Acadian owl" from Nova Scotia that had been described and illustrated in 1781 by the English ornithologist John Latham in his multi-volume work ''A General Synopsis of Birds'' ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
