Chachalacas are galliform birds from the genus Ortalis. These birds are found in wooded habitats in the far southern United States (Texas), Mexico, and Central and South America. They are social, can be very noisy and often remain fairly common even near humans, as their relatively small size makes them less desirable to hunters than their larger relatives. As agricultural pests, they have a ravenous appetite for tomatoes, melons, beans, and radishes and can ravage a small garden in short order. They travel in packs of six to twelve.  They somewhat resemble the guans, and the two have commonly been placed in a subfamily together, though the chachalacas are probably closer to the curassows.


== Taxonomy ==
The genus Ortalis was introduced (as Ortalida) by the German naturalist Blasius Merrem in 1786 with the little chachalaca (Ortalis motmot) as the type species. The generic name is derived from the Ancient Greek word όρταλις, meaning "pullet" or "domestic hen." The common name derives from the Nahuatl verb chachalaca, meaning "to chatter." With a glottal stop at the end, chachalacah was an alternate name for the bird known as the chachalahtli. All these words likely arose as an onomatopoeia for the four-noted cackle of the plain chachalaca (O. vetula). The genus contains 16 species.Mitochondrial and nuclear DNA sequence data tentatively suggest that the chachalacas emerged as a distinct lineage during the Oligocene, somewhere around 40–20 mya, possibly being the first lineage of modern cracids to evolve; this does agree with the known fossil record – including indeterminate, cracid-like birds – which very cautiously favors a north-to-south expansion of the family.

Gävle (pronounced [ˈjɛ̌ːvlɛ] (listen)) is a city in Sweden, the seat of Gävle Municipality and the capital of Gävleborg County. It had 102 418 inhabitants in 2019, which makes it the 13th most populated city in Sweden. It is the oldest city in the historical Norrland (Sweden's Northern Lands), having received its charter in 1446 from Christopher of Bavaria. However, Gävle is far nearer to the greater Stockholm region than it is to the other major settlements in Norrland and has a much milder climate than associated with said region.
In recent years, the city has received much international attention due to its large Yule Goat figure made of straw - the Gävle Goat. The goat is erected in December each year and is often subsequently vandalized, usually by being set on fire. The goat has now become a symbol for the city and is being used for various marketing purposes.


== History ==

It is believed that the name Gävle derives from the word gavel, meaning river banks in Old Swedish and referring to the Gavleån (Gävle River). The oldest settlement was called Gävle-ägarna, which means "Gavel-owners". This name was shortened to Gävle, then Gefle, and finally Gävle.

Octopus (pl. octopuses, see below for variants) relates to approximately 300 species of soft-bodied, eight-limbed molluscs of the order Octopoda (, ok-TO-pə-də). The order is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the center point of the eight limbs. The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates.
Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, and are short-lived.

North Korea, officially the Democratic People's Republic of Korea (DPRK), is a country in East Asia, constituting the northern part of the Korean Peninsula. It borders China and Russia to the north, at the Yalu (Amnok) and Tumen rivers; it borders South Korea to the south at the Korean Demilitarized Zone. Its western border is formed by Korea Bay and the Yellow Sea, while its eastern border is defined by the Sea of Japan. North Korea, like its southern counterpart, claims to be the legitimate government of the entire peninsula and adjacent islands. Pyongyang is the country's capital and largest city.
In 1910, Korea was annexed by Imperial Japan. In 1945, after the Japanese surrender at the end of World War II, Korea was divided into two zones along the 38th parallel, with the north occupied by the Soviet Union and the south occupied by the United States. Negotiations on reunification failed, and in 1948, separate governments were formed: the socialist DPRK in the north, and the capitalist First Republic of Korea in the south. The formation of the DPRK came from a number of provisional governments: the People's Republic of Korea (PRK), the Soviet Civil Administration (SCA), the Provisional People's Committee of North Korea, and the People's Committee of North Korea. The Korean War began in 1950, with an invasion by North Korea, and lasted to 1953.

The symbol # is known as the number sign, hash, or, in North American usage, pound sign. The symbol has historically been used for a wide range of purposes including the designation of an ordinal number and as a ligatured abbreviation for pounds avoirdupois – having been derived from the now-rare ℔.Since 2007, widespread usage of the symbol to introduce metadata tags on social media platforms has led to such tags being known as "hashtags", and from that, the symbol itself is sometimes called a hashtag.The symbol is distinguished from similar symbols by its combination of level horizontal strokes and right-tilting vertical strokes.


== History ==

It is believed that the symbol traces its origins to the symbol ℔, an abbreviation of the Roman term libra pondo, which translates as "pound weight". This abbreviation was printed with a dedicated ligature type, with a horizontal line across, so that the lowercase letter l would not be mistaken for the numeral 1. Ultimately, the symbol was reduced for clarity as an overlay of two horizontal strokes "=" across two slash-like strokes "//". Examples of it being used to indicate pounds exist at least as far back as 1850.The symbol is described as the "number" character in an 1853 treatise on bookkeeping, and its double meaning is described in a bookkeeping text from 1880. The instruction manual of the Blickensderfer model 5 typewriter (c. 1896) appears to refer to the symbol as the "number mark". Some early-20th-century U.S. sources refer to it as the "number sign", although this could also refer to the numero sign. A 1917 manual distinguishes between two uses of the sign: "number (written before a figure)"; and "pounds (written after a figure)". The use of the phrase "pound sign" to refer to this symbol is found from 1932 in U.S. usage.

Harry Houdini (; born Erik Weisz, later known as Ehrich Weiss or Harry Weiss; March 24, 1874 – October 31, 1926) was a Hungarian-born American escape artist, illusionist, stunt performer and mysteriarch, noted for his escape acts.He first attracted notice in vaudeville in the United States and then as "Harry 'Handcuff' Houdini" on a tour of Europe, where he challenged police forces to keep him locked up. Soon he extended his repertoire to include chains, ropes slung from skyscrapers, straitjackets under water, and having to escape from and hold his breath inside a sealed milk can with water in it.
In 1904, thousands watched as he tried to escape from special handcuffs commissioned by London's Daily Mirror, keeping them in suspense for an hour. Another stunt saw him buried alive and only just able to claw himself to the surface, emerging in a state of near-breakdown. While many suspected that these escapes were faked, Houdini presented himself as the scourge of fake spiritualists. As President of the Society of American Magicians, he was keen to uphold professional standards and expose fraudulent artists. He was also quick to sue anyone who imitated his escape stunts.
Houdini made several movies but quit acting when it failed to bring in money. He was also a keen aviator and aimed to become the first man to fly a powered aircraft in Australia.


== Early life ==
Erik Weisz was born in Budapest to a Jewish family.

The piano is an acoustic, stringed musical instrument invented in Italy by Bartolomeo Cristofori around the year 1700 (the exact year is uncertain), in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings.
The word piano is a shortened form of pianoforte, the Italian term for the early 1700s versions of the instrument,  which in turn derives from gravicembalo col piano e forte (key cymbal with quieter and louder) and fortepiano. The Italian musical terms piano and forte indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the greater the velocity of a key press, the greater the force of the hammer hitting the strings, and the louder the sound of the note produced and the stronger the attack. The name was created as a contrast to harpsichord, a musical instrument that does not allow variation in volume; compared to the harpsichord, the first fortepianos in the 1700s had a quieter sound and smaller dynamic range.A piano usually has a protective wooden case surrounding the soundboard and metal strings, which are strung under great tension on a heavy metal frame. Pressing one or more keys on the piano's keyboard causes a wooden or plastic hammer (typically padded with firm felt) to strike the strings. The hammer rebounds from the strings, and the strings continue to vibrate at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies by more efficiently coupling the acoustic energy to the air. When the key is released, a damper stops the strings' vibration, ending the sound. Notes can be sustained, even when the keys are released by the fingers and thumbs, by the use of pedals at the base of the instrument.

Steller's sea eagle (Haliaeetus pelagicus) is a large diurnal bird of prey in the family Accipitridae. It was originally described by Peter Simon Pallas in 1811. No subspecies are recognised. A sturdy eagle, it has dark brown plumage with white wings and tail, and yellow beak and talons. On average, it is the heaviest eagle in the world, at about 5 to 9 kg (11 to 20 lb), but may be below the harpy eagle (Harpia harpyja) and Philippine eagle (Pithecophaga jefferyi) in some standard measurements.The Steller's sea eagle lives in coastal northeastern Asia and mainly preys on fish and water birds. The Kamchatka Peninsula in Far Eastern Russia is known for its relatively large population of these birds. Around 4,000 of these eagles live there. Steller's sea eagle is listed as vulnerable on the International Union for Conservation of Nature (IUCN)'s Red List of Threatened species.


== Taxonomy ==
This species was first described as Aquila pelagica by Prussian naturalist Peter Simon Pallas, in 1811. The species name is the Ancient Greek pelagos "the open sea/ocean".

Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With about 360 species, they occur from Alaska to Tierra del Fuego, but the vast majority of the species is found in the tropics. They are small birds, with most species measuring 7.5–13 cm (3–5 in) in length. The smallest extant hummingbird species is the 5 cm (2.0 in) bee hummingbird, which weighs less than 2.0 g (0.07 oz). The largest hummingbird species is the 23 cm (9.1 in) giant hummingbird, weighing 18–24 grams (0.63–0.85 oz). They are specialized for feeding on flower nectar, but all species consume flying insects or spiders.
Hummingbirds split from their sister group, the swifts and treeswifts, around 42 million years ago (Mya). The common ancestor of extant hummingbirds is estimated to have lived 22 Mya. They are known as hummingbirds because of the humming sound created by their beating wings, which flap at high frequencies audible to humans. They hover in midair at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to around 80 per second in small hummingbirds.

The koala or, inaccurately, koala bear  (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats, which are members of the family Vombatidae. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
Koalas typically inhabit open eucalypt woodlands, and the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to 20 hours a day.

Theodor Seuss Geisel ( (listen); March 2, 1904 – September 24, 1991) was an American  children's author, political cartoonist, illustrator, poet, animator, and filmmaker. He is known for his work writing and illustrating more than 60 books under the pen name Dr. Seuss (,). His work includes many of the most popular children's books of all time, selling over 600 million copies and being translated into more than 20 languages by the time of his death.Geisel adopted the name "Dr. Seuss" as an undergraduate at Dartmouth College and as a graduate student at Lincoln College, Oxford. He left Oxford in 1927 to begin his career as an illustrator and cartoonist for Vanity Fair, Life, and various other publications. He also worked as an illustrator for advertising campaigns, most notably for FLIT and Standard Oil, and as a political cartoonist for the New York newspaper PM. He published his first children's book And to Think That I Saw It on Mulberry Street in 1937. During World War II, he took a brief hiatus from children's literature to illustrate political cartoons, and he also worked in the animation and film department of the United States Army where he wrote, produced or animated many productions including Design for Death, which later won the 1947 Academy Award for Best Documentary Feature.After the war, Geisel returned to writing children's books, writing classics like If I Ran the Zoo (1950), Horton Hears a Who! (1955), The Cat in the Hat (1957), How the Grinch Stole Christmas! (1957), Green Eggs and Ham (1960), One Fish Two Fish Red Fish Blue Fish (1960), The Sneetches (1961), The Lorax (1971), The Butter Battle Book (1981), and Oh, the Places You'll Go (1990).

Monaco ( (listen); French pronunciation: ​[mɔnako]), officially the Principality of Monaco (French: Principauté de Monaco), is a sovereign city-state and microstate on the French Riviera close to the Italian region of Liguria, in Western Europe. Bordered by France to the north, east and west, it is lapped by the Mediterranean Sea to the south. The principality is home to 38,682 residents, of whom 9,486 are Monégasque nationals; it is widely recognised for being one of the most expensive and wealthiest places in the world. The official language is French, although Monégasque (a dialect of Ligurian), Italian and English are spoken and understood by a sizeable group.With an area of 2.1 km2 (0.81 sq mi), it is the second smallest sovereign state in the world, after Vatican City. Its 19,009 inhabitants per square kilometre (49,230/sq mi) make it the most densely-populated sovereign state in the world. Monaco has a land border of 5.47 km (3.40 mi) and the world's shortest coastline of approximately 3.83 km (2.38 mi); it has a width that varies between 1,700 and 349 m (5,577 and 1,145 ft). The highest point in the state is a narrow pathway named Chemin des Révoires on the slopes of Mont Agel, in the Les Révoires ward, which is 161 metres (528 feet) above sea level. The principality is about 15 km (9.3 mi) from the border with Italy. Its most populous ward is Larvotto/Bas Moulins with a population of 5,443 as of 2008. Through land reclamation, Monaco's land mass has expanded by 20 percent.
