Nocturnality is a behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is " nocturnal ", versus diurnal meaning the opposite.
86-431: Nighthawks are nocturnal birds of the subfamily Chordeilinae, within the nightjar family, Caprimulgidae, which is a grouping of 92 species of medium sized birds with long wings and short bills specialized for eating insects. The nighthawk's subfamily consists of four genera: Chordeiles ; Swainson, 1832, Lurocalis ; Cassin, 1851, Podager ; Wagler, 1832, and Nyctiprogne ; Bonaparte, 1857, which are all native to
172-540: A common ancestor who evolved to function as a nocturnal species, decreasing their eyesight in favor of a better sense of smell. The anomaly to this theory were anthropoids , who appeared to have the most divergence from nocturnality of all organisms examined. While most mammals did not exhibit the morphological characteristics expected of a nocturnal creature, reptiles and birds fit in perfectly. A larger cornea and pupil correlated well with whether these two classes of organisms were nocturnal or not. Being active at night
258-485: A decrease in mate calls and continued to move around instead of waiting for a potential mate to arrive. This hurts the overall fitness of the species, which is concerning considering the overall decrease in amphibian populations. Predation Some nocturnal predator-prey relationships are interrupted by artificial lighting. Bats that are fast-moving are often at an advantage with insects being drawn to light; they are fast enough to escape any predators also attracted to
344-526: A faster pace. It is characterised by greater use of prepositions, and word order that is closer to modern Romance languages, for example, while grammatically retaining more or less the same formal rules as Classical Latin. Ultimately, Latin diverged into a distinct written form, where the commonly spoken form was perceived as a separate language, for instance early French or Italian dialects, that could be transcribed differently. It took some time for these to be viewed as wholly different from Latin however. After
430-743: A few in German , Dutch , Norwegian , Danish and Swedish . Latin is still spoken in Vatican City, a city-state situated in Rome that is the seat of the Catholic Church . The works of several hundred ancient authors who wrote in Latin have survived in whole or in part, in substantial works or in fragments to be analyzed in philology . They are in part the subject matter of the field of classics . Their works were published in manuscript form before
516-404: A few. Famous and well regarded writers included Petrarch, Erasmus, Salutati , Celtis , George Buchanan and Thomas More . Non fiction works were long produced in many subjects, including the sciences, law, philosophy, historiography and theology. Famous examples include Isaac Newton 's Principia . Latin was also used as a convenient medium for translations of important works first written in
602-418: A high breeding site fidelity, thus meaning they are especially susceptible to destabilization as a result of natural disasters such as forest fires, floods or droughts, as well as anthropogenic interventions such as development. Nighthawks have been observed migrating at all hours of the day in flocks of, at times, hundreds of birds which winter in both rural and urban regions of South America. Nighthawk migration
688-629: A long-term risk to nighthawk population stability as climate change is increasing vulnerability in larger insects due to extreme weather events and higher temperatures, thus restricting prey availability for nighthawks which cannot see the, in some circumstances, 20% smaller prey organisms. During the day, nighthawks roost in forested areas which provide them with cover from both predators and temperature fluctuations, although they may also occasionally be observed in grasslands and early successional habitats rich in foraging opportunities. Nighthawks breed in more open habitats like beaches or clearings to allow for
774-428: A lot of information regarding nightjars is conflated with information regarding nighthawks. Nighthawks are similar in most respects to the nightjars, but have shorter bills and plumage that is less soft. Nighthawks are less strictly nocturnal than many nightjars and may be seen hunting when there is still light in the sky. The subfamily Chordeilinae contains four genera and ten species. Under the genus Chordeiles exists
860-418: A major effect on nocturnal animals, as well as diurnal species. The causes of these can be traced to distinct, sometimes overlapping areas: light pollution and spatial disturbance. Light pollution is a major issue for nocturnal species, and the impact continues to increase as electricity reaches parts of the world that previously had no access. Species in the tropics are generally more affected by this due to
946-560: A native language, Medieval Latin was used across Western and Catholic Europe during the Middle Ages as a working and literary language from the 9th century to the Renaissance , which then developed a classicizing form, called Renaissance Latin . This was the basis for Neo-Latin which evolved during the early modern period . In these periods Latin was used productively and generally taught to be written and spoken, at least until

#17327758889581032-495: A number of threats to the different endangered species. Adults are likely to stay away from artificially lit beaches that they might prefer to lay eggs on, as there is less cover against predators. Additionally, baby sea turtles that hatch from eggs on artificially lit beaches often get lost, heading towards the light sources as opposed to the ocean. Rhythmic behaviors are affected by light pollution both seasonally and daily patterns. Migrating birds or mammals might have issues with
1118-470: A relatively similar spatial habitat as they did before. In comparison, herbivorous prey tend to stay in areas where human disturbance is low, limiting both resources and their spatial habitat. This leads to an imbalance in favor of predators, who increase in population and come out more often at night. In zoos , nocturnal animals are usually kept in special night-illumination enclosures to invert their normal sleep-wake cycle and to keep them active during
1204-567: A result, the list has variants, as well as alternative names. In addition to the historical phases, Ecclesiastical Latin refers to the styles used by the writers of the Roman Catholic Church from late antiquity onward, as well as by Protestant scholars. The earliest known form of Latin is Old Latin, also called Archaic or Early Latin, which was spoken from the Roman Kingdom , traditionally founded in 753 BC, through
1290-407: A separate language, existing more or less in parallel with the literary or educated Latin, but this is now widely dismissed. The term 'Vulgar Latin' remains difficult to define, referring both to informal speech at any time within the history of Latin, and the kind of informal Latin that had begun to move away from the written language significantly in the post-Imperial period, that led ultimately to
1376-709: A small number of Latin services held in the Anglican church. These include an annual service in Oxford, delivered with a Latin sermon; a relic from the period when Latin was the normal spoken language of the university. In the Western world, many organizations, governments and schools use Latin for their mottos due to its association with formality, tradition, and the roots of Western culture . Canada's motto A mari usque ad mare ("from sea to sea") and most provincial mottos are also in Latin. The Canadian Victoria Cross
1462-429: A sort of informal language academy dedicated to maintaining and perpetuating educated speech. Philological analysis of Archaic Latin works, such as those of Plautus , which contain fragments of everyday speech, gives evidence of an informal register of the language, Vulgar Latin (termed sermo vulgi , "the speech of the masses", by Cicero ). Some linguists, particularly in the nineteenth century, believed this to be
1548-572: A spoken and written language by the scholarship by the Renaissance humanists . Petrarch and others began to change their usage of Latin as they explored the texts of the Classical Latin world. Skills of textual criticism evolved to create much more accurate versions of extant texts through the fifteenth and sixteenth centuries, and some important texts were rediscovered. Comprehensive versions of authors' works were published by Isaac Casaubon , Joseph Scaliger and others. Nevertheless, despite
1634-432: A strictly left-to-right script. During the late republic and into the first years of the empire, from about 75 BC to AD 200, a new Classical Latin arose, a conscious creation of the orators, poets, historians and other literate men, who wrote the great works of classical literature , which were taught in grammar and rhetoric schools. Today's instructional grammars trace their roots to such schools , which served as
1720-693: A vernacular, such as those of Descartes . Latin education underwent a process of reform to classicise written and spoken Latin. Schooling remained largely Latin medium until approximately 1700. Until the end of the 17th century, the majority of books and almost all diplomatic documents were written in Latin. Afterwards, most diplomatic documents were written in French (a Romance language ) and later native or other languages. Education methods gradually shifted towards written Latin, and eventually concentrating solely on reading skills. The decline of Latin education took several centuries and proceeded much more slowly than
1806-568: A wingspan of about 21-22 inches (53–57 cm), short legs, and very short, wide bills that are moderately hooked at the tip. The least nighthawk ( Chordeiles pusillus ), at 6.3 inches (15–19 cm) and 23 grams (0.81 oz), is the smallest of all Caprimulgiformes , while the Nacunda nighthawk ( Chordeiles nacunda ) is one of the largest nightjars in the world measuring at 11-13 inches (28–33 cm). Nighthawks have small feet, of little use for walking, and long pointed wings. Their soft plumage

#17327758889581892-411: Is Veritas ("truth"). Veritas was the goddess of truth, a daughter of Saturn, and the mother of Virtue. Switzerland has adopted the country's Latin short name Helvetia on coins and stamps, since there is no room to use all of the nation's four official languages . For a similar reason, it adopted the international vehicle and internet code CH , which stands for Confoederatio Helvetica ,
1978-698: Is pollination - nocturnal pollinators such as moths, beetles, thrips, and bats have a lower risk of being seen by predators, and the plants evolved temporal scent production and ambient heat to attract nocturnal pollination. Like with predators hunting the same prey, some plants such as apples can be pollinated both during the day and at night. Nocturnality is a form of crypsis , an adaptation to avoid or enhance predation . Although lions are cathemeral , and may be active at any time of day or night, they prefer to hunt at night because many of their prey species ( zebra , antelope , impala, wildebeest , etc.) have poor night vision . Many species of small rodents, such as
2064-897: Is a classical language belonging to the Italic branch of the Indo-European languages . Latin was originally spoken by the Latins in Latium (now known as Lazio ), the lower Tiber area around Rome , Italy. Through the expansion of the Roman Republic it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire . By the late Roman Republic , Old Latin had evolved into standardized Classical Latin . Vulgar Latin refers to
2150-450: Is a form of niche differentiation , where a species' niche is partitioned not by the amount of resources but by the amount of time (i.e. temporal division of the ecological niche ). Hawks and owls can hunt the same field or meadow for the same rodents without conflict because hawks are diurnal and owls are nocturnal. This means they are not in competition for each other's prey. Another niche that being nocturnal lessens competition within
2236-640: Is a reversal of the original phrase Non terrae plus ultra ("No land further beyond", "No further!"). According to legend , this phrase was inscribed as a warning on the Pillars of Hercules , the rocks on both sides of the Strait of Gibraltar and the western end of the known, Mediterranean world. Charles adopted the motto following the discovery of the New World by Columbus, and it also has metaphorical suggestions of taking risks and striving for excellence. In
2322-410: Is avoiding the heat of the day. This is especially true in arid biomes like deserts , where nocturnal behavior prevents creatures from losing precious water during the hot, dry daytime. This is an adaptation that enhances osmoregulation . One of the reasons that ( cathemeral ) lions prefer to hunt at night is to conserve water. Hamiltons Frog , found on Stephens and Maud islands, stays hidden for
2408-568: Is considered one of the longest routes traveled for any North American bird. Nocturnal Nocturnal creatures generally have highly developed senses of hearing , smell , and specially adapted eyesight . Some animals, such as cats and ferrets , have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal ). Others, such as bushbabies and (some) bats , can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for
2494-427: Is cryptically coloured to resemble bark or leaves, aiding in protection from their primary predators; foxes and racoons. To promote concealment during the day, some species perch facing lengthwise along a branch, rather than across it as birds usually do. Nighthawks are generally solitary but form flocks for the purpose of migration and for elaborate mating displays. These displays begin with the males diving from high in
2580-552: Is found in any widespread language, the languages of Spain, France, Portugal, and Italy have retained a remarkable unity in phonological forms and developments, bolstered by the stabilising influence of their common Christian (Roman Catholic) culture. It was not until the Muslim conquest of Spain in 711, cutting off communications between the major Romance regions, that the languages began to diverge seriously. The spoken Latin that would later become Romanian diverged somewhat more from
2666-635: Is known regarding the discovery of nighthawks, it is believed that the term "nighthawk", first recorded in the King James Bible of 1611, was originally a local name in England for the European nightjar . Its use in the Americas to refer to members of the genus Chordeiles and related genera was first recorded in 1778 when John Cassin, a renowned ornithologist responsible for the establishment of

2752-689: Is modelled after the British Victoria Cross which has the inscription "For Valour". Because Canada is officially bilingual, the Canadian medal has replaced the English inscription with the Latin Pro Valore . Spain's motto Plus ultra , meaning "even further", or figuratively "Further!", is also Latin in origin. It is taken from the personal motto of Charles V , Holy Roman Emperor and King of Spain (as Charles I), and
2838-429: Is not needed anymore due to the evolution of compensatory sensory systems, such as a heightened sense of smell and more astute auditory systems. In a recent study, recently extinct elephant birds and modern day nocturnal kiwi bird skulls were examined to recreate their likely brain and skull formation. They indicated that olfactory bulbs were much larger in comparison to their optic lobes , indicating they both have

There are many diurnal species that exhibit some nocturnal behaviors. For example, many seabirds and sea turtles only gather at breeding sites or colonies at night to reduce the risk of predation to themselves and/or their offspring. Nocturnal species take advantage of
3268-464: The Mesozoic , many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators. A recent study attempts to answer the question as to why so many modern day mammals retain these nocturnal characteristics even though they are not active at night. The leading answer is that the high visual acuity that comes with diurnal characteristics
3354-574: The Middle Ages , borrowing from Latin occurred from ecclesiastical usage established by Saint Augustine of Canterbury in the 6th century or indirectly after the Norman Conquest , through the Anglo-Norman language . From the 16th to the 18th centuries, English writers cobbled together huge numbers of new words from Latin and Greek words, dubbed " inkhorn terms ", as if they had spilled from a pot of ink. Many of these words were used once by

This process is followed by tail-shaking, the exposing of a white patch located on the throat of the male, and vocalizations similar to croaks. Although it is unclear whether nighthawks mate for life, they are monogamous for the duration of mating season in which they develop a barren nest on the ground or another flat surface, such as an urban roof, where
4300-408: The artificial lighting. Insects are the most obvious example, who are attracted by the lighting and are usually killed by either the heat or electrical current. Some species of frogs are blinded by the quick changes in light, while nocturnal migratory birds may be disoriented, causing them to lose direction, tire out, or be captured by predators. Sea turtles are particularly affected by this, adding to

#17327758889584472-409: The careful work of Petrarch, Politian and others, first the demand for manuscripts, and then the rush to bring works into print, led to the circulation of inaccurate copies for several centuries following. Neo-Latin literature was extensive and prolific, but less well known or understood today. Works covered poetry, prose stories and early novels, occasional pieces and collections of letters, to name
4558-428: The change in their relatively constant light patterns, but temperate species relying on day-night triggers for behavioral patterns are also affected as well. Many diurnal species see the benefit of a "longer day", allowing for a longer hunting period which is detrimental to their nocturnal prey trying to avoid them. Light pollution can disorient species that are used to darkness, as their adaptive eyes are not as used to

The vast majority of written Latin belongs to this period, but its full extent is unknown. The Renaissance reinforced the position of Latin as
4816-428: The cost. The increasing amount of habitat destruction worldwide as a result of human expansion has given both advantages and disadvantages to different nocturnal animals. As a result of peak human activity in the daytime, more species are likely to be active at night in order to avoid the new disturbance in their habitat. Carnivorous predators however are less timid of the disturbance, feeding on human waste and keeping
4902-465: The country's full Latin name. Some film and television in ancient settings, such as Sebastiane , The Passion of the Christ and Barbarians (2020 TV series) , have been made with dialogue in Latin.

Cats have adapted to domestication so that each individual, whether stray alley cat or pampered housecat, can change their activity level at will, becoming nocturnal or diurnal in response to their environment or the routine of their owners. Cats normally demonstrate crepuscular behavior, bordering nocturnal, being most active in hunting and exploration at dusk and dawn.

It is attested both in inscriptions and in some of the earliest extant Latin literary works, such as the comedies of Plautus and Terence . The Latin alphabet was devised from the Etruscan alphabet . The writing later changed from what was initially either a right-to-left or a boustrophedon script to what ultimately became

Once the lights were turned off, predation levels decreased. Many diurnal prey species forced into being nocturnal are susceptible to nocturnal predators and those species with poor nocturnal eyesight often bear the brunt of
6192-424: The lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their visual sensitivity : in the low-light conditions. Nocturnality helps wasps , such as Apoica flavissima , avoid hunting in intense sunlight. Diurnal animals, including humans (except for night owls ), squirrels and songbirds, are active during
6278-408: The majority of the day when temperatures are warmer and are mainly active at night. They will only come out during the day if there are humid and cool conditions. Many plant species native to arid biomes have adapted so that their flowers only open at night when the sun's intense heat cannot wither and destroy their moist, delicate blossoms. These flowers are pollinated by bats, another creature of
6364-492: The males to perform their mating rituals. In October 2018, the University of Alberta published research on the common nighthawk revealing that it travels 20,000 km (12,000 mi) every year during migration between the rainforests and savannas of Brazil and its breeding grounds in northern Alberta. Further research has determined that, in addition to this annual migration between general regions, nighthawks demonstrate
6450-428: The night time to prey on species that are used to avoiding diurnal predators. Some nocturnal fish species will use the moonlight to prey on zooplankton species that come to the surface at night. Some species have developed unique adaptations that allow them to hunt in the dark. Bats are famous for using echolocation to hunt down their prey, using sonar sounds to capture them in the dark. Another reason for nocturnality
6536-428: The night. Climate-change and the change in global temperatures has led to an increasing amount of diurnal species to push their activity patterns closer towards crepuscular or fully nocturnal behavior. This adaptive measure allows species to avoid the heat of the day, without having to leave that particular habitat. The exponential increase in human expansion and technological advances in the last few centuries has had
6622-743: The noise "pee-yah". Nighthawks are visually reliant predators that feed on flying insects such as beetles (Coleoptera), sawflies, bees, ants, and wasps (Hymenoptera), flies (Diptera), caddisflies (Trichoptera), butterflies, and moths (Lepidoptera) by opening their wide mouths to allow for the entrance of the insects as they are traveling. Areas of high precipitation, cool temperature, or high elevation are therefore unfavorable to nighthawks because flying insects are less mobile in such conditions. Nighthawks are most often observed hunting during crepuscular periods, or during twilight, which necessitates good eyesight with insects shorter than 5mm eliciting no reaction from experimental nighthawks. This consideration could pose
6708-466: The other varieties, as it was largely separated from the unifying influences in the western part of the Empire. Spoken Latin began to diverge into distinct languages by the 9th century at the latest, when the earliest extant Romance writings begin to appear. They were, throughout the period, confined to everyday speech, as Medieval Latin was used for writing. For many Italians using Latin, though, there
6794-461: The past experienced difficulty in categorizing members of this group, however new advancements in molecular phylogeny have allowed for more conclusive classification. Thanks to these techniques, it is now understood that there are nine genera in the family, not 16 as previously accepted, and that there are two main subfamilies: Caprimulginae (nightjars) and Chordeilinae which is the subfamily that nighthawks belong to. Because of this taxonomic complexity,
6880-451: The same species. This unselective hostility can result in a decline in the average proportion of breeding individuals in a population in densely occupied territories, even below that of the carrying capacity established by available resources. This means that prey availability is not commonly cited as a concern for the conservation of nighthawks, but rather that habitat loss can be damaging to population stability. Nighthawks are mostly active in
6966-704: The timing of their movement for example. On a day-to-day basis, species can see significant changes in their internal temperatures, their general movement, feeding and body mass. These small scale changes can eventually lead to a population decline, as well as hurting local trophic levels and interconnecting species. Some typically diurnal species have even become crepuscular or nocturnal as a result of light pollution and general human disturbance. There have been documented effects of light pollution on reproductive cycles and factors in different species. It can affect mate choice , migration to breeding grounds, and nest site selection. In male green frogs , artificial light causes
7052-443: The western hemisphere. Species in the family Caprimulgidae exhibit similarities in plumage appearance, a fact that some attribute to convergent evolution , which occurs when species that do not share an evolutionary history develop similar adaptations, while others attribute it to parallelism which is the process by which similar adaptations arise in members of closely related species or populations. Because of this, taxonomists in
7138-413: Was free to develop on its own, there is no reason to suppose that the speech was uniform either diachronically or geographically. On the contrary, Romanised European populations developed their own dialects of the language, which eventually led to the differentiation of Romance languages . Late Latin is a kind of written Latin used in the 3rd to 6th centuries. This began to diverge from Classical forms at
7224-496: Was much more liberal in its linguistic cohesion: for example, in classical Latin sum and eram are used as auxiliary verbs in the perfect and pluperfect passive, which are compound tenses. Medieval Latin might use fui and fueram instead. Furthermore, the meanings of many words were changed and new words were introduced, often under influence from the vernacular. Identifiable individual styles of classically incorrect Latin prevail. Renaissance Latin, 1300 to 1500, and
7310-441: Was no complete separation between Italian and Latin, even into the beginning of the Renaissance . Petrarch for example saw Latin as a literary version of the spoken language. Medieval Latin is the written Latin in use during that portion of the post-classical period when no corresponding Latin vernacular existed, that is from around 700 to 1500 AD. The spoken language had developed into the various Romance languages; however, in
7396-482: Was shut down in June 2019), and Vatican Radio & Television, all of which broadcast news segments and other material in Latin. A variety of organisations, as well as informal Latin 'circuli' ('circles'), have been founded in more recent times to support the use of spoken Latin. Moreover, a number of university classics departments have begun incorporating communicative pedagogies in their Latin courses. These include
