Lesser Nighthawk
The lesser nighthawk (''Chordeiles acutipennis'') is a nightjar found throughout a large part of the Americas. The adults are dark with brown, grey and white patterning on the upperparts and breast; the long upperwings are black and show a white bar in flight. The tail is dark with white barring; the underparts are buffy with fine black horizontal streaking. The adult male has a white throat; the female has a light brown throat. This bird looks similar to the common nighthawk, but is slightly smaller, has a slightly less deeply forked tail, and is more buffy in coloration. The calls are also completely different. The lesser nighthawk has a rapid, low whistled melodious trill, lasting several seconds. It is usually heard only near breeding areas. Their breeding habitat is open country from the Southwestern United States through Central America to tropical South America. They usually nest on bare ground, sometimes in raised locations including stumps and boulders or flat house ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Hermann
Johann, or Jean-Frederic, Hermann, or Herrmann, (31 December 1738 in Barr, Alsace – 4 October 1800 in Strasbourg) was a French physician and naturalist. In 1769 he was appointed professor of medicine at the School of Public Health of Strasbourg, then, in 1778, professor of philosophy, before going on, in 1784, to succeed Jacob Reinbold Spielmann as chair of chemistry, natural history and materia medica. In 1794 he became professor of botany and materia medica in the new School of Medicine. He was the author of ''Tabula affinitatum animalium '' (1783) and ''Observationes zoologicae quibus novae complures'', published posthumously in 1804. His collections and library of 18,000 volumes formed the basis of the Natural History Museum of Strasbourg, where a reconstruction of his natural history cabinet was opened in 1988 . Hermann was also in charge of Strasbourg's botanical garden, where he was responsible for a large increase in the number of living plant species. The garde ...

Nightjar
Nightjars are medium-sized nocturnal or crepuscular birds in the family Caprimulgidae and order Caprimulgiformes, characterised by long wings, short legs, and very short bills. They are sometimes called goatsuckers, due to the ancient folk tale that they sucked the milk from goats (the Latin for goatsucker is ''caprimulgus''), or bugeaters, their primary source of food being insects. Some New World species are called nighthawks. The English word "nightjar" originally referred to the European nightjar. Nightjars are found all around the world, with the exception of Antarctica and certain island groups such as the Seychelles. They can be found in a variety of habitats, most commonly the open country with some vegetation. They usually nest on the ground, with a habit of resting and roosting on roads. The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. Typical nightjars, though, have rictal bristle ...

Common Nighthawk
The common nighthawk (''Chordeiles minor'') is a medium-sized crepuscular or nocturnal bird of the Americas within the nightjar family, whose presence and identity are best revealed by its vocalization. Typically dark (gray, black and brown), displaying cryptic colouration and intricate patterns, this bird is difficult to spot with the naked eye during the day. This bird is most conspicuous when in its buoyant and erratic flight. The most remarkable feature of this aerial insectivore is its small beak that belies the massiveness of its mouth. Some claim appearance similarities to owls. With its horizontal stance and short legs, the common nighthawk does not travel frequently on the ground, instead preferring to perch horizontally, parallel to branches, on posts, on the ground or on a roof. The males of this species may roost together but the bird is primarily solitary. The common nighthawk shows variability in territory size. This caprimulgid has a large, flattened head with larg ...

Southwestern United States
The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longit ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent.

Crepuscular
In zoology, a crepuscular animal is one that is active primarily during the twilight period, being matutinal, vespertine, or both. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daylight and of darkness, respectively. Some crepuscular animals may also be active by moonlight or during an overcast day. Matutinal animals are active only before sunrise, and vespertine only after sunset. A number of factors impact the time of day an animal is active. Predators hunt when their prey is available, and prey try to avoid the times when their principal predators are at large. The temperature at midday may be too high or at night too low. Some creatures may adjust their activities depending on local competition. Etymology and usage The word ''crepuscular'' derives from the Latin '' crepusculum'' ("twilight"). Its sense accordingly differs from diurnal and nocturnal behavior, which respectively peak during hours of daylight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Rio Grande Valleys
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 swimming. Birds ...
