98-510: Nine - see text Lovebird is the common name for the genus Agapornis , a small group of parrots in the Old World parrot family Psittaculidae . Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar . Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and

For a full list, see List of earthquakes in California . Note: Earthquakes with epicenters in the Los Angeles Metro Area are marked with the (#) symbol. Other earthquakes mentioned indicates shaking was felt in the region. As of the 2020 United States Census , Southern California has

294-636: A M w   6.7 earthquake or greater, such as the San Andreas Fault , which can produce M w   8.0 or greater. The largest known earthquake in California was the 1857 Fort Tejon earthquake that ruptured 200+ miles (320+ kilometers) of the San Andreas Fault from Parkfield to Wrightwood . With a recurrence interval of roughly 150 years, this part of the San Andreas fault is well within its window to produce another large earthquake. Along with

Without this interaction, daily exercise, a roomy cage/aviary, and many toys to play with, they may resort to feather-plucking or screaming, and both behaviors can be difficult to cure. If the owner leaves the house, they should leave a radio or TV set playing to provide sound for the bird. Lovebirds are intelligent, and if a relationship is to form they need a human who will dedicate much time to them. Lovebirds enjoy baths and like to sun themselves daily. As with pet parrots in general,

490-581: A higher population, with 23.76 million residents as of the 2020 census . The sparsely populated desert region of California occupies a significant portion (part of which has even been proposed to be split into a new county due to cultural, economic and geographic differences relative to the rest of the more urban region) of the area: the Colorado Desert , along with the Colorado River , is located on Southern California's eastern border with Arizona , and

588-643: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,

784-606: A population of 23,762,904. Despite a reputation for high growth rates, Southern California's population has grown slower than the state average since the 2000s. This is due to California's growth becoming concentrated in the northern part of the state as result of a stronger, tech-oriented economy in the Bay Area and an emerging Greater Sacramento region. Southern California consists of one Combined Statistical Area , eight Metropolitan Statistical Areas , one international metropolitan area , and multiple metropolitan divisions. The region

882-466: A population of approximately 4 million, Los Angeles is the most populous city in California and the second most populous in the United States. South of Los Angeles and with a population of approximately 1.4 million is San Diego, the second most populous city in the state and the eighth most populous in the nation. The counties of Los Angeles , San Diego , Orange , Riverside , and San Bernardino are

980-413: A prey animal. Lovebirds of different species can mate and produce both sterile and fertile hybrid offspring, for example Agapornis personatus mate with Agapornis fischeri will produce fertile hybrid offspring. These offspring have behaviours of both parents. For this reason it is recommended to only place birds of the same species together, or of the same sex. There are two lovebird societies in

In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;

1274-484: A threat to themselves. Toe biting may occur when lovebirds are socialising/housed with small birds (i.e. parrotlets , budgies, and even docile cockatiels). They should not be housed with other bird genera as they can be injured or pose a threat to other birds. Lovebirds are very vocal birds, making loud, high-pitched noises. Some make noise all day, especially during dawn and dusk. This is a normal parrot behaviour as flock animals, where they are calling to each other before

1372-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

1470-754: A whole enacted the Alquist Priolo Special Studies Zone Act in the wake of the 1971 San Fernando earthquake . The act prohibits new construction of residential buildings closer than 50 feet (15 m) from a surface rupturing active fault zone. In addition, the act improved safety by requiring new structures (both residential and commercial) to be seismically retrofitted. It also required existing infrastructure to comply. Since 1972, numerous large magnitude earthquakes have struck Southern California with little widespread damage in part due to act. However, exceptions can be noted for epicenters that lie directly on top of densely populated regions such as

1568-407: Is 1 ‍ m   × ‍ 1 ‍ m   × ‍ 1 ‍ m. Lovebird's beaks are made of keratin, which grows continuously. Chewing and destroying wood toys and perches helps to keep beaks trim. Cuttlebones help provide beak-trimming and a source of calcium and other necessary minerals. Natural perches and special rough surfaced perches of varying diameters placed at different levels in

1666-418: Is 10 to 12 years. Lovebirds are 13–17 cm (5–7 in) in length, up to 24 cm in wingspan with 9 cm for a single wing and 40–60 g ( 1 + 1 ⁄ 2 –2 oz) in weight. They are among the smallest parrots, characterised by a stocky build, a short blunt tail, and a relatively large, sharp beak. Wildtype lovebirds are mostly green with a variety of colours on their upper body, depending on

1764-502: Is also home to a large surf and skateboard culture. Companies such as Vans , Volcom , Quiksilver , No Fear , Stüssy , RVCA , and Body Glove are all headquartered there. Skateboarder Tony Hawk ; surfers Rob Machado , Timmy Curran , Bobby Martinez , Pat O'Connell , Dane Reynolds , and Chris Ward live in Southern California. Some of the most famous surf locations are in Southern California as well, including Trestles , Rincon , The Wedge , Huntington Beach , and Malibu . Some of

1862-505: Is also known for its mountain resort communities, such as Big Bear Lake , Lake Arrowhead , and Wrightwood , and their ski resorts, like Bear Mountain , Snow Summit , Snow Valley Mountain Resort , and Mountain High . The inland desert city of Palm Springs is also popular. Southern California is generally considered the area of California south of the latitude 35°45', approximately one-third of

1960-670: Is an important government, arts and entertainment, and retail district. Downtown San Diego is the CBD of San Diego, though the city is filled with business districts. These include Carmel Valley , Del Mar Heights , Mission Valley , Rancho Bernardo , Sorrento Mesa , and University City . Most of these districts are located in Northern San Diego and some within North County regions. Los Angeles Orange County Riverside & San Bernardino San Diego Southern California

2058-428: Is best to spend frequent, short periods of time with a lovebird, rather than having just one or two interactions every day. Determining the sex of a lovebird is difficult. At maturity of one year, it may show signs of whether it is male or female, such as ripping up paper and stuffing it into its feathers (female behaviour) or regurgitating for its owners (male behaviour: the male feeds the nesting female). This behaviour

For instance, A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the Interim Register of Marine and Nonmarine Genera (IRMNG). The type genus forms

2254-493: Is easily aroused in lovebirds, however, and they may bite unless humans establish a bond with gentle handling. Provided with adequate space, a stimulating environment, and appropriate nutrition, lovebirds can become companion parrots . They snuggle with and will often preen their favorite people. It is preferable to obtain birds bred in captivity, rather than birds caught in the wild. Wild birds may harbor diseases such as avian polyomavirus . Captured wild lovebirds also may mourn

2450-545: Is home to two extended metropolitan areas that exceed five million in population. These are the Greater Los Angeles Area at 17,786,419, and San Diego–Tijuana at 5,105,768. Of these metropolitan areas, the Los Angeles-Long Beach-Santa Ana metropolitan area , Riverside-San Bernardino-Ontario metropolitan area , and Oxnard-Thousand Oaks-Ventura metropolitan area form Greater Los Angeles; while

2548-436: Is important to use wide cages as large as possible. Few lovebirds talk, but many will not: there is a chance they may learn to mimic human sounds if taught to do so at a young age. Lovebirds are noisy, with calls ranging from cheerily pleasant to highly irritating; in the wild, parrots must call to each other over long distances to keep flocks together, and it is through such signals that they make most of their communication. It

2646-401: Is low to moderate depending on the area. Rain is infrequent, but is often heavy when it does occur, making flash floods an aspect of living in Southern California. This climatic pattern was alluded to in the hit song " It Never Rains (In Southern California) ". While snow is very rare in lower elevations, mountains above 5,000 feet (1,500 m) receive plentiful snowfall in the winter. Since

2744-458: Is not a reliable indicator, however. The only sure method is DNA testing; however, some experts can sex lovebirds by feeling beneath the body. There are two sharp points beneath the cloaca known as the pelvic bone. If the points are nearer together, the bird is male; if the points are further away, it is female (females must have a larger pelvis to lay eggs). Lovebirds require an appropriately sized cage or aviary. Minimum recommended space per bird

2842-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

2940-427: Is the black-collared lovebird ( Agapornis swindernianus ). The genus contains nine species of which five are monotypic and four are divided into subspecies. They are native to mainland Africa and the island of Madagascar . In the wild, the different species are separated geographically. Traditionally, lovebirds are divided into three groups: However, this division is not fully supported by phylogenetic studies, as

3038-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

They also require plenty of toys, such as willow branches, swings, tunnels, boxes and safe things to chew on and play with. Lack of toys, keeping the birdcage covered too many hours, and lack of companionship or social stimulation may lead to boredom, stress and psychological or behavioral problems (nervousness, aggression, feather-plucking, screaming, depression, immunosuppression). Lovebirds are social birds and will enjoy several hours of interaction

Lovebirds are no longer imported from the wild to the United States. Birds socialised from a very early age, while being brought up by parents, make very good pets. The practice of hand-feeding young psittacines, including lovebirds, outside of a medical emergency has been outlawed in

Several species are also found in feral populations in Southern California . There are two feral colonies present in the Pretoria region (Silver Lakes, Faerie Glen and Centurion) in South Africa. They probably originated from birds that escaped from aviaries. They consist mostly of masked, black cheeked, Fischer and hybrid birds and vary in colours. White (not albino) and yellow as well as blue occur in many cases. The white ringed eyes are very prominent. With their inclination to bond, lovebirds can form long-term relationships with people as well as other lovebirds. Aggression

Once the lovebirds start constructing their nest, mating will follow. During this time, the lovebirds will mate repeatedly. Eggs follow 3–5 days later. The female will spend hours inside her nesting box before eggs are laid. Once

7350-526: The provisions of the ICZN Code, e.g., incorrect original or subsequent spellings, names published only in a thesis, and generic names published after 1930 with no type species indicated. According to "Glossary" section of the zoological Code, suppressed names (per published "Opinions" of the International Commission of Zoological Nomenclature) remain available but cannot be used as the valid name for

7448-466: The same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but the French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or

7546-408: The scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of a species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in

7644-468: The sole county to vote for the GOP, with Orange County having been Democrat since 2012. Southern California is one of the largest economies in the United States. It is dominated by, and heavily dependent upon, the abundance of petroleum, as opposed to other regions where automobiles are not nearly as dominant, due to the vast majority of transport that runs on this fuel. Southern California is famous for tourism and

7742-566: The southern section of the San Andreas (in the Palm Springs region, which has not ruptured in ~400 years), the entire Southern California portion of the San Andreas Fault is ready to produce a powerful earthquake in the near future. Notable faults capable of large magnitude events include the San Jacinto Fault (a splay of the San Andreas that runs directly under the I-10 & I-215 interchange),

7840-416: The species of the dimorphic group are not grouped together in a single clade . Species and subspecies: [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] [REDACTED] Depending on the species of lovebird, the female will carry nesting material into

7938-572: The species. The Fischer's lovebird, black-cheeked lovebird, and the masked lovebird have a prominent white ring around their eyes. Many colour mutant varieties have been produced by selective breeding of the species that are popular in aviculture . The genus Agapornis was introduced by the English naturalist Prideaux John Selby in 1836. The name combines the Ancient Greek αγάπη agape meaning "love" and όρνις ornis meaning "bird". The type species

8036-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

8134-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

8232-544: The start of the day and just before they settle down for the night. Lovebirds are also very active and love to chew things, especially paper. When they are flying within a household, it is wise to watch them carefully and protect any furniture, electrical wiring or anything else that they could possibly chew on. Try to place fresh willow or oak branches in a favourite spot (e.g. near a high/sunny platform) to satisfy this natural behaviour. Other things to be aware of when keeping lovebirds (also applies to other pet birds) at home are

8330-461: The state, formed by the northern boundaries of San Luis Obispo , Kern , and San Bernardino counties, which are not exactly a straight line. Another definition for Southern California uses Point Conception and the Tehachapi Mountains as the northern geographical barriers, especially when defining California's bioregions . In this definition, Owens Valley and Death Valley are part of

8428-403: The taxon is termed a synonym ; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names. A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for

8526-428: The tips of lovebirds' toenails should wear down adequately by the parrot climbing over rough surfaced perches. If the parrot has an inactive lifestyle the toenails may grow long and need to be trimmed. Only the very tips of the toenails are trimmed. If too much of a toenail is trimmed away, it will be painful and bleed from the blood vessels in the centre of the nail. This bleeding should be stopped as soon as possible with

8624-417: The top eight largest cities in the United States. In Southern California, there are also 14 cities with more than 200,000 residents and 48 cities over 100,000 residents. Many of Southern California's most developed cities lie along or in close proximity to the coast, with the exception of San Bernardino and Riverside. Southern California has drifted left since 2004, and is solidly Democrat. Kern County remains

8722-830: The use of styptic gel or powder. Sharp pointed toenails can be blunted by simply filing the point. These procedures are usually done with the help of an assistant carefully holding the parrot wrapped in a towel. A fresh mix (with or without dehydrated fruits and/or vegetables) of excellent quality combining various seeds, grains and nuts generally represent the typical basic diet. Ideally the basic mix will contain or will be supplemented with an about 30% portion of any bio/organic (naturally coloured and flavoured and without any conservative agent) and/or of any natural (naturally coloured, flavoured and preserved) pellets. Parrot species (including cockatiels ) are biologically vegetarian species. Consequently, they should be fed vegetarian diets that are ideally supplemented with vegetable proteins provided by

8820-566: The values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes. Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up

8918-429: The virus species " Salmonid herpesvirus 1 ", " Salmonid herpesvirus 2 " and " Salmonid herpesvirus 3 " are all within the genus Salmonivirus ; however, the genus to which the species with the formal names " Everglades virus " and " Ross River virus " are assigned is Alphavirus . As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in

9016-429: The world's busiest general aviation airport; major commercial airports at San Bernardino , Orange County , Bakersfield , Ontario , Burbank , and Long Beach ; and numerous smaller commercial and general aviation airports. Six of the seven lines of the commuter rail system, Metrolink , run out of Downtown Los Angeles, connecting Los Angeles, Ventura , San Bernardino, Riverside, Orange, and San Diego counties with

9114-435: The world's largest action sports events, including the X Games , Boost Mobile Pro , and the U.S. Open of Surfing , are held in Southern California. The region is also important to the world of yachting with premier events including the annual Transpacific Yacht Race , or Transpac , from Los Angeles to Hawaii. San Diego Yacht Club hosted the three America's Cup races from 1988 to 1995. The first modern-era triathlon

9212-515: Was grouped with other counties of the San Joaquin Valley , California's central agricultural valley. Southern California consists of a heavily developed urban environment, home to some of the largest urban areas in the state, along with the Deserts of California (part of which was even proposed to become a new county due to cultural, economic and geographic differences relative to the rest of

9310-585: Was held in San Diego's Mission Bay in 1974. Since then, Southern California, and San Diego in particular, have become a mecca for triathlon and multi-sport racing, products, and culture. Southern California has multiple sports franchises and networks, such as Fox Sports Net . Many of these locals and tourists frequent the Southern California coast for its beaches. Some of Southern California's most popular beaches are Malibu , Laguna Beach , La Jolla , Manhattan Beach , and Hermosa Beach . Southern California

9408-536: Was high in the Bakersfield-Kern County , Santa Maria , and San Luis Obispo areas. Most of Southern California has a Mediterranean -like climate, with warm and dry summers, mild and wet winters, where cool weather and freezing temperatures are rare. Southern California contains other types of climates, including semi-arid , desert and mountain , with infrequent rain and many sunny days. Summers are hot or warm, and dry, while winters are mild, and rainfall

9506-689: Was the name of a proposed new state which failed to get on the 2018 California ballot. The ballot measure proposed splitting the existing state into three parts. In December 2020, during the COVID-19 pandemic , the state government led by Governor Gavin Newsom divided the state into five regions for the purpose of issuing stay-at-home orders. The Southern California region consisted of the following counties: Imperial , Inyo , Los Angeles , Mono , Orange , Riverside , San Bernardino , San Diego , San Luis Obispo , Santa Barbara , and Ventura . However, Kern County

9604-756: Was to include a portion of the much larger Tulare County and all of San Luis Obispo County . The proposal was sent to Washington, D.C. , with a strong advocate in Senator Milton Latham . However, the secession crisis following the election of Abraham Lincoln in 1860 and the subsequent American Civil War led to the proposal never coming to a vote. In 1900, the Los Angeles Times defined Southern California as including "the seven counties of Los Angeles, San Bernardino, Orange, Riverside, San Diego, Ventura, and Santa Barbara." This definition left out San Luis Obispo and Kern counties. Southern California
