Virginia Rail
The Virginia rail (''Rallus limicola'') is a small waterbird, of the family Rallidae. These birds remain fairly common despite continuing loss of habitat, but are secretive by nature and more often heard than seen. They are also considered a game species in some provinces and states, though rarely hunted. The Ecuadorian rail is often considered a subspecies, but some taxonomic authorities consider it distinct. Description Adults are mainly brown, darker on the back and crown, with orange-brown legs. To walk through dense vegetation, they have evolved a laterally compressed body and strong forehead feathers adapted to withstand wear from pushing through vegetation. Virginia rails have the highest ratio of leg-muscle to flight-muscle of all birds (25% - 15% of body weight respectively). They have long toes used to walk on floating vegetation. Their tail is short and they have a long slim reddish bill. Their cheeks are grey, with a light stripe over the eye and a whitish throat. C ...

Birds Of Mexico
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 fur ...

Birds Of North America
The lists of birds in the light blue box below are divided by biological family. The lists are based on ''The AOS Check-list of North American Birds'' of the American Ornithological Society and ''The Clements Checklist of Birds of the World'' supplemented with checklists from Panama, Greenland, and Bermuda. It includes the birds of Greenland, Canada, the United States (excluding Hawaii), Mexico, Central America, Bermuda, and the West Indies. Taxonomy The taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) ''Check-list of North American Birds'', the recognized scientific authority on the taxonomy and nomenclature of North America birds. The AOS's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the ''Check-list'', "strongly and unanimously continues to endorse the biological spe ...

Pair Bond
In biology, a pair bond is the strong affinity that develops in some species between a mating pair, often leading to the production and rearing of young and potentially a lifelong bond. Pair-bonding is a term coined in the 1940s that is frequently used in sociobiology and evolutionary biology circles. The term often implies either a lifelong Monogamy in animals, socially monogamous relationship or a stage of mating interaction in socially monogamous species. It is sometimes used in reference to human relationships. Varieties According to evolutionary psychologists David P. Barash and Judith Lipton, from their 2001 book ''The Myth of Monogamy'', there are several varieties of pair bonds: *''Short-term pair-bond:'' a transient mating or associations *''Long-term pair-bond:'' bonded for a significant portion of the life cycle of that pair *''Lifelong pair-bond:'' mated for life *''Social pair-bond:'' attachments for territorial or social reasons *''Clandestine pair-bond:'' quick extr ...

Clutch (eggs)
A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abundance of prey), while some species are determinant layers, laying a species-specific number of egg ...

Monogamous
Monogamy ( ) is a relationship of two individuals in which they form a mutual and exclusive intimate partnership. Having only one partner at any one time, whether for life or serial monogamy, contrasts with various forms of non-monogamy (e.g., polygamy or polyamory). The term monogamy, derived from Greek for “one marriage,” has multiple context-dependent meanings—genetic, sexual, social, and marital—each varying in interpretation across cultures and disciplines, making its definition complex and often debated. The term is typically used to describe the behavioral ecology and sexual selection of animal mating systems, referring to the state of having only one mate at any one given time. In a human cultural context, monogamy typically refers to the custom of two individuals, regardless of orientation, committing to a sexually exclusive relationship. Monogamy in humans varies widely across cultures and definitions. While only a minority of societies are strictly mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sora (bird)
The sora, sora rail or Carolina crake (''Porzana carolina'') is a small waterbird of the rail family Rallidae, sometimes also referred to as the sora rail or sora crake, that occurs throughout much of North America. The genus name ''Porzana'' is derived from Venetian terms for small rails, and the specific ''carolina'' refers to the Carolina Colony. The common name "Sora" is probably taken from a Native American language. Adult soras are long, with dark-marked brown upperparts, a blue-grey face and underparts, and black and white barring on the flanks. They have a short thick yellow bill, with black markings on the face at the base of the bill and on the throat. Sexes are similar, but young soras lack the black facial markings and have a whitish face and buff breast. They weigh about . The sora's breeding habitat is marshes throughout much of North America. They nest in a well-concealed location in dense vegetation. The female usually lays 10 to 12 eggs, sometimes as many a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern 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. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...
