Jurong Bird Park
Jurong Bird Park is an aviary and tourist attraction in Jurong, Singapore. The largest such bird park in Asia, it covers an area of on the western slope of Jurong Hill, the highest point in the Jurong region. It is one of the parks managed by Mandai Wildlife Reserve, which are also the managers of Singapore Zoo, Night Safari and River Wonders. In 2016, the Mandai Wildlife Group announced that the Jurong Bird Park would be relocated to a much larger park at Mandai Lake Road by 2020, consolidating with the three existing wildlife parks together with a new Rainforest Park to form an integrated nature and wildlife precinct known as the Mandai Wildlife Reserve. In 2021, the group announced that the park's successor in Mandai would be named Bird Paradise. In 2022, it was announced that Jurong Bird Park will close on 3 January 2023 to finalise its move to Bird Paradise at Mandai. History The idea of a permanent aviary was first conceived by the late Dr Goh Keng Swee, then Minist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviculture
Aviculture is the practice of keeping and breeding birds, especially of wild birds in captivity. Types There are various reasons that people get involved in aviculture. Some people breed birds to preserve a species. Some people breed parrots as companion birds, and some people breed birds to make a profit. Aviculture Aviculture is the practice of keeping birds (class ''Aves'') in captivity using controlled conditions, normally within the confines of an aviary, for hobby, business, research and conservation purposes. Some reasons for aviculture are: breeding birds to preserve the species because many avian species are at risk due to habitat destruction and natural disaster. Aviculture encourages conservation, provides education about avian species, provides companion birds for the public, and includes research on avian behaviour. Publications and avicultural societies Publications on aviculture include books on species which include pets, books on breeding and introductory b ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pionites Melanocephalus -Tiputini-6c
Caique ( or ) refers to a group of 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" (which is sometimes further split into three separate species - green-thighed parrot, yellow-tailed parrot and black-legged parrot) to describe the nominal species. 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. Description The two primary nominal species are best distinguished by the black-headed caique'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 nominal species. ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloaca
In animal anatomy, a cloaca ( ), plural cloacae ( or ), is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles and birds, and a few mammals (monotremes, tenrecs, golden moles, and marsupial moles), have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory openings with analogous purpose in some invertebrates are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulation, commonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
