For example, most hospitals employ many types of workers around the clock: "The Lark-Owl Scale: When Couples' Sleep Patterns Diverge", "Epidemiology of the human circadian clock", "Career Outlook: Careers for night owls and early birds", The Munich ChronoType Questionnaire (MCTQ), https://en.wikipedia.org/w/index.php?title=Lark_(person)&oldid=934028549, Creative Commons Attribution-ShareAlike License. For fieldlark, or titlark, see pipit. Denken Sie darüber nach, wie eifersüchtig Sie sind, wenn Sie ihnen sagen, dass Sie Ihre lark bird auf Aliexpress haben. They nest on the ground and avoid wooded or bushy areas. Most species build nests on the ground, usually cups of dead grass, but in some species the nests are more complicated and partly domed. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree....

They also lack a pessulus, the bony central structure in the syrinx of songbirds. A lark, early bird, morning person or, in Scandinavian countries, an A-person, is a person who usually gets up early in the morning and goes to bed early in the evening. Many employees in these industries start working at or before 7:00 a.m.[9] Some professions are well-known for their early morning hours, including bakers, school teachers, dairy farmers, and surgeons. Human "larks" tend to feel most energetic just after they get up in the morning. [14] Larks incubate for 11 to 16 days. Chestnut and white stripes streak across the head, a black mustache runs down the sides of the throat, and the cheeks have chestnut spots. Researchers have traditionally used the terms morningness and eveningness to describe these two phenotypes. The bill is quite variable: it may be small and narrowly conical or long and downward-curving; and the hind claw is long and sometimes straight. People with late chronotypes go to bed late and rise late. Industries that tend to be favorable to morning larks include farming, construction, and working for public utilities. The larks that can sing the full 13 sounds in the correct order are highly valued, while any disruption in the songs will decrease its value significantly. a small, brown bird with a pleasant song lark noun [C] (ACTIVITY) an activity done for enjoyment or amusement: He started hang-gliding years ago as a lark. Plumage is plain or streaked (sexes usually alike) in a colour closely matching the soil. The opposite of the lark is the owl, often awake at night. [10] The phylogeny of larks (Alaudidae) was reviewed in 2013, leading to the recognition of the arrangement below.[11][12]. Larks occur throughout the continental Old World; only the horned, or shore, lark (Eremophila alpestris) is native to the New World. A few desert species nest very low in bushes, perhaps so circulating air can cool the nest. [2] Biological processes, including sleep-wake patterns, that display an oscillation of about 24 hours are called circadian rhythms. However, in larks the tarsus (the lowest leg bone, connected to the toes) has only one set of scales on the rear surface, which is rounded. [6] Some authorities, such as the British Ornithologists' Union[7] and the Handbook of the Birds of the World, adhere to that placement. Updates? Most have streaked brown plumage, some boldly marked with black or white. However, many other classifications follow the Sibley-Ahlquist taxonomy in placing the larks in a large oscine subgroup Passerida (which excludes crows, shrikes and their allies, vireos, and many groups characteristic of Australia and southeastern Asia). Many species dig with their bills to uncover food. They are thus well-suited for working the day shift. [4] They have multiple scutes on the hind side of their tarsi, rather than the single plate found in most songbirds. Larks are passerine birds of the family Alaudidae. [13] Larks' eggs are usually speckled. When the word "lark" is used without specification, it often refers to the Eurasian skylark (Alauda arvensis). As circadian rhythm is independent of the number of hours of sleep a person needs, Roenneberg calculates the rhythm based on the midpoint of the sleep period. At a finer level of detail, some now place the larks at the beginning of a superfamily Sylvioidea with the swallows, various "Old World warbler" and "babbler" groups, and others. According to the researchers, its existence in people skews sleep pattern even if the period also cover eight hours.

Corrections? [2][3] Larks are a well-defined family, partly because of the shape of their tarsus.

[13], Larks, commonly consumed with bones intact, have historically been considered wholesome, delicate, and light game. [8] Infants also tend to be early risers.[8]. A 2007 survey of over 55,000 people found that chronotypes tend to follow a normal distribution, with extreme morning and evening types on the far ends.
