Bumblebee Hummingbird
The bumblebee hummingbird (''Selasphorus heloisa'') is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is endemic to Mexico, but has occurred as a vagrant in the United States. Taxonomy and systematics The International Ornithological Committee (IOC), the North American Classification Committee of the American Ornithological Society, and the Clements taxonomy place the bumblebee hummingbird in genus ''Selasphorus''. BirdLife International's Handbook of the Birds of the World (HBW) places it in genus ''Atthis''. The three worldwide taxonomic systems assign two subspecies, the nominate ''S. h. heloisa''/''A. h. heliosa'' and ''S. h. margarethae''/''A. h. margarethae''.Clements, J. F., T. S. Schulenberg, M. J.

Birds Of The Sierra Madre Del Sur
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Selasphorus
''Selasphorus'' is a genus of hummingbirds from Middle and North America. Taxonomy The genus ''Selasphorus'' was introduced in 1832 by the English naturalist William John Swainson to accommodate the rufous hummingbird which is now the type species. The name combines the Ancient Greek ''selas'' meaning "light" or "flame" with ''-phoros'' meaning "-carrying". The genus contains the following nine species: The wine-throated hummingbird and the bumblebee hummingbird were formerly placed in the genus ''Atthis''. Molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to ... studies published in 2014 and 2017 found that ''Atthis'' was embedded within ''Selasphorus''. The genera were therefore merged and these hummingbirds were moved to ''Selasphorus''. References Ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropods
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-lik ...

Cloudforest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the '' International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity rich ecosystems in the world with a large amount of species directly or indirectly depending on them. Other moss forests include black spruce/ feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses including ''Hylocomium splendens'', '' Pleurozium schreberi'' and ...

Evergreen Forest
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, Live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones. Species of trees Coniferous temperate evergreen forests are most frequently dominated by species in the families. The trees include: Pinaceae and Cupressaceae. Broadleaf temperate evergreen forests include those in which Fagaceae, such as oaks and ferns are common, those in which Nothofagaceae predominate, and the eucalyptus forests of the Southern Hemisphere. There also are assorted temperate evergreen forests dominated by other families of trees, such as Lauraceae in laurel forest. Regions Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of , Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and O ...

Huachuca Mountains
The Huachuca Mountains are part of the Sierra Vista Ranger District of the Coronado National Forest in Cochise County in southeastern Arizona, approximately south-southeast of Tucson and southwest of the city of Sierra Vista. Included in this area is the highest peak in the Huachucas, Miller Peak, and the region of the Huachucas known as Canelo Hills in eastern Santa Cruz County. The mountains range in elevation from at the base to at the top of Miller Peak. The second highest peak in this range is Carr Peak, elevation . The Huachuca Mountain area is managed principally by the United States Forest Service (Coronado National Forest) (41%) and the U.S. Army (Fort Huachuca) (20%), with much of the rest being private land (32%). Sierra Vista is the main population center (43,888 inhabitants as of the 2010 Census). The Huachuca Mountains were named by the Spanish for a Pima village that once existed to the north of the range near the present location of Elgin, Arizona. Corona ...
