Crop (anatomy)
The crop (also the croup, the craw, the ingluvies, and the sublingual pouch) is a thin-walled, expanded portion of the alimentary tract, which is used for the storage of food before digestion. The crop is an anatomical structure in vertebrate animals, such as birds, and invertebrate animals, such as gastropods (snails and slugs), earthworms, leeches, and insects. Insects Cropping is used by bees to temporarily store nectar of flowers. When bees "suck" nectar, it is stored in their crops. Other Hymenoptera also use crops to store liquid food. The crop in eusocial insects, such as ants, has specialized to be distensible, and this specialization enables important communication between colonial insects through trophallaxis. The crop can be found in the foregut of insects. Birds In a bird's digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pionites Leucogaster -Zoologico De Sao Paulo -Brazil-6a
Caique ( or ) refers to two to four species of parrots in the genus ''Pionites'' endemic to the Amazon Basin in South America. Name The term "caique" is primarily used in aviculture, with ornithologists typically referring to them as the black-headed parrot and white-bellied parrot, the latter of which is sometimes further split into three separate species, green-thighed parrot, yellow-tailed parrot and black-legged parrot. They have historically been called the "seven-colored parrot". They are relatively small and stocky, with a short, square tail and bright colors; this may be why they are referred to as "caique" based on the term for a similarly described Turkish vessel. They exhibit high social intelligence. Description The two species are best distinguished by the black-headed parrot's black crown; both have white "bellies". Their typical weight is 150–170 grams, with the white-bellied species being the larger and heavier of the two species. They can live up to 40 y ...

Gullet
The esophagus (American English), oesophagus (British English), or œsophagus ( archaic spelling) ( see spelling difference) all ; : ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''esophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, "I carry") + ἔφαγον (éphagon, "I ate"). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of ...

Parrot
Parrots (Psittaciformes), also known as psittacines (), are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genus (biology), genera, found mostly in tropics, tropical and subtropics, subtropical regions. The four families are the Psittaculidae (Old World parrots), Psittacidae (African and New World parrots), Cacatuidae (cockatoos), and Strigopidae (New Zealand parrots). One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk (Red List Index, IUCN Red List Index) than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperateness, temperate regions as well. The greatest biodiversity, diversity of parrots is in South America and Australasia.

Domesticated Turkey
The domestic turkey (''Meleagris gallopavo domesticus'') is a large fowl, one of the two species in the genus '' Meleagris'' and the same species as the wild turkey. Although turkey domestication was thought to have occurred in central Mesoamerica at least 2,000 years ago, recent research suggests a possible second domestication event in the area that is now the southwestern United States between 200 BC and 500 AD. However, all of the main domestic turkey varieties today descend from the turkey raised in central Mexico that was subsequently imported into Europe by the Spanish in the 16th century. The domestic turkey is a popular form of poultry. It is raised throughout temperate parts of the world, partially because industrialized farming has made it very cheap for the amount of meat it produces. Female domestic turkeys are called ''hens'', and the chicks are '' poults'' or '' turkeylings''. In Canada and the United States, male turkeys are called ''toms''. In the United Kingdom a ...

Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world. Chickens are primarily kept for chicken as food, their meat and egg as food, eggs, though they are also kept as pets. As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and cultural references to chickens, feature prominently in folklore, religion, and literature across many societies. Their economic importance makes them a central component of global animal husbandry and agricu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttonquail
Buttonquail or hemipodes are members of a small family of birds, Turnicidae, which resemble, but are not closely related to, the quails of Phasianidae. They inhabit warm grasslands in Asia, Africa, Europe, and Australia. There are 18 species in two genera, with most species placed in the genus '' Turnix'' and a single species in the genus '' Ortyxelos''. Buttonquails are small, drab, running birds, which avoid flying. The female is the more richly colored of the sexes. While the quail-plover is thought to be monogamous, ''Turnix'' buttonquails are sequentially polyandrous: both sexes cooperate in building a nest in the earth, but normally only the male incubates the eggs and tends the young, while the female may go on to mate with other males. Taxonomy The genus ''Turnix'' was introduced in 1791 by French naturalist in Pierre Bonnaterre. The genus name is an abbreviation of the genus '' Coturnix''. The type species was subsequently designated as the common buttonquail. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New World Quail
The New World quail are small birds, that despite their similar appearance and habits to the Old World quail, belong to a different family known as the Odontophoridae. In contrast, the Old World quail are in the Phasianidae family, sharing only a remote phylogenetic connection with their New World counterparts through their mutual classification within the Phasianoidea superfamily. The geographical range of the New World quail extends from Canada to southern Brazil, and two species, the California quail and the bobwhite quail, have been successfully introduced species, introduced to New Zealand. The stone partridge and Nahan's partridge, both found in Africa, seem to belong to the family. Species are found across a variety of habitats from tropical rainforest to deserts, although few species are capable of surviving at very low temperatures. There are 34 species divided into 10 genus, genera. The legs of most New World quails are short but powerful, with some species having very t ...

Old World Quail
Old World quail is a collective name for several genera of mid-sized birds in the tribe Coturnicini of the pheasant family Phasianidae. Although all species commonly referred to as "Old World quail" are in the same tribe, they are paraphyletic with respect to the other members of the tribe, such as '' Alectoris'', '' Tetraogallus'', '' Ammoperdix'', '' Margaroperdix'', and '' Pternistis''. New World quail are also found in the Galliformes, but are not in the same family ( Odontophoridae). Buttonquails are not closely related at all, but are named for their similar appearance. They are presently placed in the family Turnicidae of the Charadriiformes, classified as shorebirds. The collective noun for a group of quail is '' flock'', ''bevy'' or ''covey''. Taxonomy Old World quail may refer to the following species of Coturnicini: *Genus '' Synoicus'' ** Brown quail, ''Synoicus ypsilophorus'' ** Snow Mountain quail, ''Synoicus monorthonyx'' ** Blue quail, ''Synoicus adansonii ...

Quail
Quail is a collective name for several genera of mid-sized birds generally placed in the order Galliformes. The collective noun for a group of quail is a flock, covey, or bevy. Old World quail are placed in the family Phasianidae, and New World quail are placed in the family Odontophoridae. The species of buttonquail are named for their superficial resemblance to quail, and form the family Turnicidae in the order Charadriiformes. The king quail, an Old World quail, often is sold in the pet trade, and within this trade is commonly, though mistakenly, referred to as a "button quail". Many of the common larger species are farm-raised for table food or egg consumption, and are hunted on game farms or in the wild, where they may be released to supplement the wild population, or extend into areas outside their natural range. In 2007, 40 million quail were produced in the United States. New World *Genus '' Callipepla'' ** Scaled quail, (commonly called blue quail) ''Callip ...

Eagle
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family of the Accipitridae. Eagles belong to several groups of Genus, genera, some of which are closely related. True eagles comprise the genus ''Aquila (bird), Aquila''. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—two in North America, nine in Central and South America, and three in Australia. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Etymology The word "eagle" is borrowed into English from and , both derived ultimately from ("eagle"). It is cognate with terms such as , and . It is broadly synonymous with the less common English term "erne" or "earn", deriving from , from , in which it acts as the usual word for the bird. The Old English term is turn derived from and is cognate with other synonymous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawk
Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents, except Antarctica. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks, and others. This subfamily are mainly woodland birds with short broad wings, long tails, and high visual acuity. They hunt by dashing suddenly from a concealed perch. In America, members of the '' Buteo'' group are also called hawks, though birds of this group are called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged and shorter-tailed than accipiters, and fly further distances in open areas. Buteos descend or pounce on their prey rather than engaging in fast, horizontal pursuit. The terms ''accipitrine hawk'' and ''buteonine hawk'' are used to distinguish between the types in regions where ''hawk'' applies to both. The term ''"true hawk"'' is sometimes used for the accipitrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raptor (bird)
Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily insectivorous birds such as passerines (e.g. shrikes), nightjars ...
