White-tailed Hummingbird
The white-tailed hummingbird (''Eupherusa poliocerca'') is a Near Threatened species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to southwestern Mexico.HBW and BirdLife International (2021) Handbook of the Birds of the World and BirdLife International digital checklist of the birds of the world. Version 6. Available at: http://datazone.birdlife.org/userfiles/file/Species/Taxonomy/HBW-BirdLife_Checklist_v6_Dec21.zip retrieved August 7, 2022 Taxonomy and systematics The white-tailed hummingbird is monotypic. However, in the past some authors have treated the Oaxaca hummingbird (''E. cyanophrys'') as a subspecies of it. Others have treated the white-tailed as a subspecies of the stripe-tailed hummingbird (''E. eximia'').Arizmendi, M. d. C., C. I. Rodríguez-Flores, C. A. Soberanes-González, and T. S.

Daniel Giraud Elliot
Daniel Giraud Elliot (March 7, 1835 – December 22, 1915) was an American zoologist and the founder of the American Ornithologist Union. Life He was born in New York City on March 7, 1835, to George and Rebecca Elliot. In 1858, he married Ann Eliza Henderson. From 1869 to 1879, he was in London and established strong links to British ornithologists and naturalists. Elliot used his wealth to publish a series of sumptuous color-plate books on birds and other animals. Elliot wrote the text himself and commissioned artists such as Joseph Wolf and Joseph Smit, both of whom had worked for John Gould, to provide the illustrations. The books included ''A Monograph of the Phasianidae (Family of the Pheasants)'' (1870–72), ''A Monograph of the Paradiseidae or Birds of Paradise'' (1873), ''A Monograph of the Felidae or Family of Cats'' (1878) and ''Review of the Primates'' (1913). In 1890, he was President of the American Ornithologists' Union. Elliot became the first curator of zoolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Described In 1871
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] |
Endemic Birds Of Southern Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eupherusa
''Eupherusa'' is a genus of hummingbirds in the family Trochilidae. It contains the following five species: The Mexican woodnymph was formerly placed in the genus ''Thalurania'' with other species with "woodnymph" in their English names. A molecular phylogenetic study published in 2014 found that ''Thalurania'' was monophyletic, non-monophyletic and that the Mexican woodnymph is closely related to species in ''Eupherusa''. Based on this result the Mexican woodnymph is now placed in ''Eupherusa''. References Eupherusa, Taxonomy articles created by Polbot {{hummingbird-stub ...

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] |
Xeno-canto
xeno-canto is a citizen science project and Information repository, repository in which volunteers record, upload and annotate recordings of Bird vocalization, birdsong and bird calls. Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences. Each recording on the website is accompanied by a spectrogram and location data on a map displaying geographical variation. Data from xeno-canto has been re-used in many (a few thousand) scientific papers. It has also been the source of data for an annual challenge on automatic birdsong recognition ("BirdCLEF") since 2014, conducted as part of the Conference and Labs of the Evaluation Forum. The website is supported by a number of academic and birdwatching institutions worldwide, with its primary support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macaulay Library
The Macaulay Library is the world's largest archive of animal sounds. It includes more than 33 million photographs, 1.2 million audio recordings, and over two hundred thousand videos covering 96 percent of the world's bird species. There are an ever-increasing numbers of insect, fish, frog, and mammal recordings. The Library is part of Cornell Lab of Ornithology of Cornell University. History Arthur Augustus Allen and Peter Paul Kellogg made the first recordings of bird sound on May 18, 1929 in an Ithaca park. They used motion-picture film with synchronized sound to record a song sparrow, a house wren, and a rose-breasted grosbeak. This was the Beginning of Cornell Library of Natural Sounds. Graduate student Albert R. Brand and Cornell undergraduate M. Peter Keane developed recording equipment for use in the open field. In the next two years they had successfully recorded more than 40 species of birds. In 1931 Peter Keane and True McLean (a Cornell professor in Electrical Engineeri ...

Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), 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 exoskeleton, 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 Organ (anatomy), organs; it has an open circulatory system.
