Fork-tailed Flycatcher
The fork-tailed flycatcher (''Tyrannus savana'') is a passerine bird of the tyrant flycatcher family, and is the member of a genus typically referred to as kingbirds. Named for their distinguishingly long, forked tail, fork-tailed flycatchers are seen in lightly forested or grassland areas, from southern Mexico, to south past Argentina. They are most frequently observed sitting on conspicuous perches waiting for flying arthropods to fly past, they then Hawking (birds), sally out, eat their prey, and return to their perches. Northern populations near southern Mexico tend to be permanent residents, while fork-tailed flycatchers that live further south are migrants with a reputation to wanderer bird, wander as far north as the Eastern Seaboard of the United States. Taxonomy The fork-tailed flycatcher was described in 1760 by Mathurin Jacques Brisson under the French name "" () and then again in 1780 by Georges-Louis Leclerc, Comte de Buffon, Georges-Louis Buffon under the name "" (be ...

Panama
Panama ( , ; es, link=no, Panamá ), officially the Republic of Panama ( es, República de Panamá), is a transcontinental country spanning the southern part of North America and the northern part of South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's million people. Panama was inhabited by indigenous tribes before Spanish colonists arrived in the 16th century. It broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Canal to be completed by the United States Army Corps of Eng ...

Migration (ecology)
Migration, in ecology, is the large-scale movement of members of a species to a different environment. Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type. Migration is often cyclical, frequently occurring on a seasonal basis, and in some cases on a daily basis. Species migrate to take advantage of more favorable conditions with respect to food availability, safety from predation, mating opportunity, or other environmental factors. While members of some species learn a migratory route on their first journey with older members of their group, other species genetically pass on information regarding their migratory paths. Despite many differences in organisms’ migratory cues and behaviors, “considerable similarities appear to exist in the cues involved in the different phases of migration.” Migratory organisms use environmental cues like photoperiod and we ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove
A mangrove is a shrub or tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse, as a result of convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs, and became widely distributed in part due to the movement of tectonic plates. The oldest known fossils of mangrove palm date to 75 million years ago. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions. They contain a complex salt filtration system and a complex root system to cope with saltwater immersion and wave action. They are adapted to the low-oxygen conditions of wate ...

Riparian Forest
A riparian forest or riparian woodland is a forested or wooded area of land adjacent to a body of water such as a river, stream, pond, lake, marshland, estuary, canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface f ..., Sink (geography), sink or reservoir. Etymology The term riparian comes from the Latin word ''ripa'', 'river bank'; technically it only refers to areas adjacent to flowing bodies of water such as rivers, streams, Swamp, sloughs and estuaries. However, the terms ''riparian forest'' and ''riparian zone'' have come to include areas adjacent to non-flowing bodies of water such as ponds, lakes, playas and reservoirs. Characteristics Riparian forests are subject to frequent Flood, inundation. Riparian forests help control sediment, reduce the damaging effects of flo ...

Shiny Cowbird
The shiny cowbird (''Molothrus bonariensis'') is a passerine bird in the New World family Icteridae. It breeds in most of South America except for dense forests and areas of high altitude such as mountains. Since 1900 the shiny cowbird's range has shifted northward, and it was recorded in the Caribbean islands as well as the United States, where it is found breeding in southern Florida. It is a bird associated with open habitats, including disturbed land from agriculture and deforestation. Adults are sexually dimorphic. Males are all black with a purple-blue iridescence. The female is smaller, with dull brown plumage that is sometimes paler on the underparts. Females of the species can be distinguished from the female brown-headed cowbird by their longer, finer bills and flatter heads. The shiny cowbird's diet consists mainly of insects, other arthropods and seeds, and they have been recorded foraging for grains in cattle troughs. Like most other cowbirds, it is an obligate broo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrannus Savana - Fork-tailed Flycatcher XC112746
''Tyrannus'' is a genus of small passerine birds of the tyrant flycatcher family native to the Americas. The majority are named as kingbirds. Description They prefer semi-open or open areas. These birds wait on an exposed perch and then catch insects in flight. They have long pointed wings and large broad bills. These birds tend to defend their breeding territories aggressively, often chasing away much larger birds. A kingbird was photographed in 2009 defending its young by landing on and sinking its talons into the back of a red-tailed hawk and pecking its skull until the red-tailed hawk gave up and flew away. Taxonomy The genus was introduced in 1799 by the French naturalist Bernard Germain de Lacépède with the eastern kingbird (''Tyrannus tyrannus'') as the type species. The genus name is the Latin Latin (, or , ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages.

Primary Feathers
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices (), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds have evolved to perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nominate Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scissor-tailed Flycatcher
The scissor-tailed flycatcher (''Tyrannus forficatus''), also known as the Texas bird-of-paradise and swallow-tailed flycatcher, is a long-tailed bird of the genus ''Tyrannus'', whose members are collectively referred to as kingbirds. The kingbirds are a group of large insectivorous (insect-eating) birds in the tyrant flycatcher (Tyrannidae) family. The scissor-tailed flycatcher is found in North and Central America. Latin name and etymology Its former Latin name was ''Muscivora forficata''. The former genus name ''Muscivora'' derives from the Latin words for 'fly' () and 'to devour' (), while the species name ''forficata'' derives from the Latin word for 'scissors' (). The scissortail is now considered to be a member of the ''Tyrannus'', or 'tyrant-like' genus. This genus earned its name because several of its species are extremely aggressive on their breeding territories, where they will attack larger birds such as crows, hawks and owls.
