Happy Wren
The happy wren (''Pheugopedius felix'') is a species of bird in the family Troglodytidae. It is Endemism, endemic to the Pacific slope of western Mexico, from the state of Sonora (state), Sonora to the state of Oaxaca (state), Oaxaca, and also on islands west of the Mexican coast. As with other species of ''Pheugopedius'', older sources (e.g. Howell and Webb) classify it within genus ''Thryothorus''. Some authorities have treated it as a subspecies of ''P. rutilus'' or ''P. sclateri''. There is significant geographical variation, and six subspecies are recognized: ''P. f. sonorae'' is found in southern Sonora and northern Sinaloa (state), Sinaloa; ''P. f. pallidus'' is found in central Sinaloa, western Durango (state), Durango and southwards to Jalisco and Michoacán (state), Michoacán; ''P. f. lawrencii'' and ''P. f. magdalenae'' are found on different islands of the Islas Marías; ''P. f. grandis'' is found in the Balsas River basin, and the nominate subspecies, ''P. f. feli ...

Islas Marías
The Islas Marías ("Mary Islands") make up an archipelago in Mexico, consisting of four islands. They are located in the Pacific Ocean, some off the coast of the state of Nayarit and about southeast of the tip of Baja California. They are part of the municipality (''municipio'') of San Blas, Nayarit. The islands were used as a penal colony until February 18, 2019, when President Andrés Manuel López Obrador ordered the closure of its operation as Islas Marías Federal Prison. The first European to encounter the islands was Diego Hurtado de Mendoza, a cousin of Hernán Cortés in 1532, who gave them the name Islas Magdalenas. He found no evidence of prior habitation by the Native Americans. In 2010 the archipelago was designated the Islas Marías Biosphere Reserve by UNESCO. Geography The islands have an aggregate area of and a population of 1,116 on Isla María Madre as of the census of 2005 along with around 8,000 prisoners. The other islands are uninhabited.

Birds Described In 1859
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furthe ...

Pheugopedius
''Pheugopedius'' is a genus of wrens in the family Troglodytidae that are found in Central and South America. Taxonomy The genus ''Pheugopedius'' was introduced in 1851 by the German ornithologist Jean Cabanis to accommodate a single species, ''Pheugopedius genibarbis'' a junior synonym of ''Thryothorus genibarbis'' Swainson, 1837, the moustached wren. The genus contains the following 13 species: * Black-throated wren (''Pheugopedius atrogularis'') * Rufous-breasted wren (''Pheugopedius rutilus'') * Moustached wren (''Pheugopedius genibarbis'') * Coraya wren (''Pheugopedius coraya'') * Plain-tailed wren (''Pheugopedius euophrys'') * Grey-browed wren (''Pheugopedius schulenbergi'') * Black-bellied wren (''Pheugopedius fasciatoventris'') * Sooty-headed wren (''Pheugopedius spadix'') * Speckle-breasted wren (''Pheugopedius sclateri'') * Happy wren The happy wren (''Pheugopedius felix'') is a species of bird in the family Troglodytidae.

Pseudomyrmex
''Pseudomyrmex'' is a genus of stinging, wasp-like ants in the subfamily Pseudomyrmecinae. They are large-eyed, slender ants, found mainly in tropical and subtropical regions of the New World. Distribution and habitat ''Pseudomyrmex'' is predominantly Neotropical in distribution, but a few species are known from the Nearctic region. Most species are generalist twig nesters, for instance, '' Pseudomyrmex pallidus'' may nest in the hollow stems of dead grasses, twigs of herbaceous plants, and in dead, woody twigs. However, the genus is best known for several species that are obligate mutualists with certain species of ''Acacia ''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Austral ...''.

Acacia Tree
''Acacia'', commonly known as wattles or acacias, is a genus of about of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa, South America, and Australasia, but is now reserved for species mainly from Australia, with others from New Guinea, Southeast Asia, and the Indian Ocean. The genus name is Neo-Latin, borrowed from Koine Greek (), a term used in antiquity to describe a preparation extracted from ''Vachellia nilotica'', the original type species. Several species of ''Acacia'' have been introduced to various parts of the world, and two million hectares of commercial plantations have been established. Description Plants in the genus ''Acacia'' are shrubs or trees with bipinnate leaves, the mature leaves sometimes reduced to phyllodes or rarely absent. There are 2 small stipules at the base of the leaf, but sometimes fall off as the leaf matures. The flowers are borne in spike ...

Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or it may be a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high, usually with many plant stem, ...

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balsas River
The Balsas River (Spanish Río Balsas, also locally known as the Mezcala River, or Atoyac River) is a major river of south-central Mexico. The basin flows through the states of Guerrero, México, Morelos, and Puebla. Downstream of Ciudad Altamirano, Guerrero, it forms the border between Guerrero and Michoacán. The river flows through the Sierra Madre del Sur, and empties into the Pacific Ocean at Mangrove Point, adjacent to the city of Lázaro Cárdenas, Michoacán. Several rapids along the course of the Balsas River limit its navigability and thus the river has been largely used for generation of hydroelectric power, flood control and irrigation. History The Balsas River valley was possibly one of the earliest maize growing sites in Mexico, dating from around 9200 years ago. Though it is known that successive communities of Yopis, Nahuatl-speaking Cohuixcas, Matlatzincas, Chontales, Tlahuicas and Xochimilcas have lived in the region, archeological excavations in the ...
