WikiAves is a free Brazilian site of bird watchers and aims to support, publicize and promote the activity of bird watching, through photographic and sound records, species identification and communication between observers. On the site are registered photos and sounds of bird species that occur in Brazil.
The site was founded on December 16, 2008, and developed by Reinaldo Guedes. As of December 2018, there were over 2.4 million photos and 150,000 sound recordings of 1,880 different species, contributed by 30,000 users. Users contribute images and sound files, along with tentative identifications, and the community helps confirm the species photographed. [1]
According to Fatbirder's Birding Website, WikiAves ranks first in online popularity of bird watching sites. [2] According to the Commented List of birds of Brazil by the Brazilian Ornithological Registries Committee, 1919 bird species have been identified in Brazil. So 98.3% of bird species scientifically registered in Brazil have a WikiAves record. [3]
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device like binoculars or a telescope, by listening for bird sounds, watching public webcams, or by viewing smart bird feeder cameras.
The white-faced ibis is a wading bird in the ibis family, Threskiornithidae.
The laughing gull is a medium-sized gull of North and South America. Named for its laugh-like call, it is an opportunistic omnivore and scavenger. It breeds in large colonies mostly along the Atlantic coast of North America, the Caribbean, and northern South America. The two subspecies are L. a. megalopterus — which can be seen from southeast Canada down to Central America — and L. a. atricilla, which appears from the West Indies to the Venezuelan islands. The laughing gull was long placed in the genus Larus until its present placement in Leucophaeus, which follows the American Ornithologists' Union.
Wilson's snipe is a small, stocky shorebird. The generic name Gallinago is Neo-Latin for a woodcock or snipe from Latin gallina, "hen" and the suffix -ago, "resembling". The specific name delicata is Latin for "dainty".
The British Ornithologists' Union (BOU) aims to encourage the study of birds (ornithology) around the world in order to understand their biology and aid their conservation. The BOU was founded in 1858 by Professor Alfred Newton, Henry Baker Tristram and other scientists. Its quarterly journal, Ibis, has been published continuously since 1859.
The red-eyed vireo is a small American songbird. It is somewhat warbler-like but not closely related to the New World warblers (Parulidae). Common across its vast range, this species is not considered threatened by the IUCN.
The buff-bellied pipit or American pipit is a small songbird found on both sides of the northern Pacific. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica. It was formerly classified as a form of the water pipit. It is known as "American pipit" in North America and "buff-bellied pipit" in Eurasia.
The olive-sided flycatcher is a small to medium sized passerine bird in the family Tyrannidae, the Tyrant flycatcher family. It is a migratory species that travels from South to North America to breed during the summer. It is a very agile flyer and mainly consumes flying insects on flight. Since 2016, this species has been assessed as being near-threatened globally (IUCN) and threatened in Canada (SRA) due to its declining populations.
The hooded warbler is a New World warbler. It breeds in eastern North America across the eastern United States and into southernmost Canada (Ontario). It is migratory, wintering in Central America and the West Indies. Hooded warblers are very rare vagrants to western Europe.
The agami heron is a medium-sized heron. It is a resident breeding bird from Central America south to Peru and Brazil. It is sometimes known as the chestnut-bellied heron, and is the only member of the genus Agamia. In Brazil it is sometimes called Soco beija-flor, meaning 'hummingbird heron', thanks to its unique coloration pattern.
The great black hawk is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures.
The tropical kingbird is a large tyrant flycatcher. This bird breeds from southern Arizona and the lower Rio Grande Valley of Texas in the United States through Central America, South America as far as south as central Argentina and eastern Peru, and on Trinidad and Tobago. Birds from the northernmost and southern breeding areas migrate to warmer parts of the range after breeding.
The Cornell Lab of Ornithology is a member-supported unit of Cornell University in Ithaca, New York, which studies birds and other wildlife. It is housed in the Imogene Powers Johnson Center for Birds and Biodiversity in Sapsucker Woods Sanctuary. Approximately 250 scientists, professors, staff, and students work in a variety of programs devoted to the Lab's mission: interpreting and conserving the Earth's biological diversity through research, education, and citizen science focused on birds. Work at the Lab is supported primarily by its 75,000 members.
The undulated tinamou is a species of ground bird found in a wide range of wooded habitats in eastern and northern South America.
The chestnut-bellied flowerpiercer is a species of bird in the family Thraupidae. It is endemic to Colombia.
The swallow-tailed cotinga is a species of passerine bird in the family Cotingidae. It is the only member of the genus Phibalura.
The black-necked stilt is a locally abundant shorebird of American wetlands and coastlines. It is found from the coastal areas of California through much of the interior western United States and along the Gulf of Mexico as far east as Florida, then south through Central America and the Caribbean to Brazil, Peru and the Galápagos Islands, with an isolated population, the Hawaiian stilt, in Hawaii. The northernmost populations, particularly those from inland, are migratory, wintering from the extreme south of the United States to southern Mexico, rarely as far south as Costa Rica; on the Baja California peninsula it is only found regularly in winter. Some authorities, including the IUCN, treat it as a synonym of Himantopus himantopus.
xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. 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.
iNaturalist is an American 501(c)(3) nonprofit social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. iNaturalist may be accessed via its website or from its mobile applications. iNaturalist includes an automated species identification tool, and users further assist each other in identifying organisms from photographs. As of 24 February 2024, iNaturalist users had contributed approximately 172,751,520 observations of plants, animals, fungi, and other organisms worldwide, and around 350,000 users were active in the previous 30 days.
Hawkwatching is a mainly citizen science activity where experienced volunteers count migratory raptors in an effort to survey migratory numbers. Groups of hawkwatchers often congregate along well-known migratory routes such as mountain ridges, coastlines and land bridges, where raptors ride on updrafts created by the topography. Hawkwatches are often formally or informally organized by non-profit organizations such as an Audubon chapter, state park, wildlife refuge or other important birding area. Some hawkwatches remain independent of any organizing structure.
