The tits are active, noisy, social birds. They are territorial during the breeding season. The tits are highly adaptable and, after the corvids (crows and jays) and parrots, amongst the most intelligent of all birds.
The tits make a variety of calls and songs. They are amongst the most vocal of all birds, calling continuously and loudly. They are only ever silent for reasons such as avoiding predators or when intruding on a rival's territory. Quiet calls are made while feeding to keep contact with others in their social group. Other calls are used for signalling alarm—the most famous of which is the "Chic-a-dee-dee" of North American species in the genus "Poecile". The call also serves a rallying call to summon others to mob and harass the predator. It has been demonstrated through experiments that the number of "dee" syllables at the end of the call increases with the level of danger the predator poses.
The tits are insectivorous, and eat a wide range of small insects and other invertebrates, particularly small leaf-eating caterpillars. They also eat seeds and nuts, especially in winter. A typical activity is "hanging", where they inspect a branch or twig and leaves from all angles while hanging upside down to feed.
In areas with several species of tit, the different species will forage (search) in different parts of a tree. Larger species search on the ground, medium sized species search on larger branches, and the smallest species on the ends of branches. If they get larger prey or seeds, tits will do 'hold-hammering'. They hold the item with one foot, and hammer it with their bill (beak) until it is open. In this way they can open hazelnuts in 20 minutes.
Many birds store food in a cache or hiding place. They hoard supplies of food for the winter. These caches are usually of seeds but may be of insects.
Sulfur tetrafluoride
Sulfur tetrafluoride, also known as sulfur(IV) fluoride, is a chemical compound. Its chemical formula is SF. It contains sulfur in its +4 oxidation state.
Sulfur tetrafluoride is a colorless gas. It is toxic and corrosive. It releases hydrogen fluoride when exposed to water.
It is made by reacting sodium fluoride, chlorine, and sulfur dichloride. The chlorine does not have to be included. If no chlorine is used, other products form that need to be taken out.
Sulfur tetrafluoride is used to make organic molecules containing fluoride ions. It is not used much.
Sulfur dichloride
Sulfur dichloride, also known as sulfur(II) chloride, is a chemical compound. Its chemical formula is SCl. It contains sulfur in its +2 oxidation state. It also contains chloride ions.
Sulfur dichloride is a red liquid. It has a strong odor. It is a common sulfur chloride. It reacts with water to make hydrochloric acid and sulfur dioxide. When it is old, it might have some chlorine in it. It reacts with fluorides to make sulfur tetrafluoride.
It is made by reacting chlorine with sulfur. Disulfur dichloride is an intermediate. It is also a common impurity in sulfur dichloride.
Disulfur dichloride
Disulfur dichloride, also known as sulfur(I) chloride, is a chemical compound. Its chemical formula is SCl. It contains sulfur in its +1 oxidation state. It contains chlorine in its -1 oxidation state.
It is a yellow or orange liquid. It smokes in air because it reacts with water. It releases sulfur, sulfur dioxide, and hydrochloric acid when reacted with water. It reacts with chlorine to make sulfur dichloride. It can dissolve sulfur.
It is made by reacting a little chlorine with sulfur. A lot of chlorine would make sulfur dichloride.
It is used to place sulfur atoms some organic compounds.
Sulfur fluoride
Sulfur fluoride can refer to any of these chemical compounds:
Sulfur chloride
Sulfur chloride can refer to any of these chemical compounds:
Tetrasulfur tetranitride
Tetrasulfur tetranitride, also known as tetrasulphur tetranitride, is a chemical compound. Its chemical formula is SN. It contains sulfur in its +3 oxidation state. It also contains nitride ions.
It is a gold solid. It is an explosive, releasing sulfur and nitrogen when detonated. The purer the substance is, the more easily it explodes. It is pale yellow when cold, orange at normal temperature, and red when hot. It reacts with bases. It can be split into disulfur dinitride when it is reacted with silver. It does not dissolve in water.
It can be made by reacting disulfur dichloride with ammonia. It can also be made by reacting ammonium chloride with disulfur dichloride.
It can be used to react with many organic compounds.
It is an explosive, so it should not be ground. Explosion releases harmless nitrogen and sulfur.
Sulfur nitride
Sulfur nitride can refer to either of these chemical compounds:
Disulfur dinitride
Disulfur dinitride is a chemical compound. Its chemical formula is SN. It contains sulfur in its +3 oxidation state. It also contains nitride ions.
Disulfur dinitride is a colorless crystalline solid. It is explosive, similar to tetrasulfur tetranitride. It easily evaporates. It does not dissolve in water. It turns back into tetrasulfur tetranitride when exposed to water.
Disulfur dinitride is produced by reacting elemental silver with tetrasulfur tetranitride. This forms silver(I) sulfide, which acts as a catalyst. This reaction happens in a vacuum.
It reacts with some chemical compounds that are acids.
I puritani
I puritani is an Italian opera in three acts by Vincenzo Bellini, first performed in Paris, on January 25, 1835, libretto by Carlo Pepoli, after Jacques Ancelot and Xavier Boniface Saintine's "Têtes Rondes et Cavaliers", itself based on Sir Walter Scott's "Old Morality". Bellini's last work and one of his greatest triumphs.
La sonnambula
La sonnambula is an Italian opera in two acts by Vincenzo Bellini, first performed at La Scala in Milan, on March 6, 1831, libretto by Felice Romani, after Eugène Sribe's ballet-pantomime "La somnanbule". Bellini's most pastoral work, it was an immediate success and is still regularly performed.
Mary Quant
Dame Barbara Mary Quant (born 11 February 1934) is a British fashion designer. In 1963, she won the "Sunday Times" International Fashion Award, and was chosen as "Woman of the Year".
Quant is famous as a designer who invented the miniskirt and hot pants. She was also instrumental in the mod fashion movement, and known for her use of pop art in fashion.
Born to Welsh parents in Blackheath, London, Quant went to Blackheath High School, then studied illustration at Goldsmiths College. Her first employment was as a couture milliner (hat maker).
In November 1955, she teamed up with her husband, Alexander Plunket Greene, and a former solicitor, Archie McNair, to open a clothes shop on the Kings Road in Chelsea called Bazaar. Bazaar's best sellers were small white plastic collars to brighten up black dresses or t-shirts. Black stretch stockings were also popular.
Skirts had been getting shorter since about 1958 – a development Mary Quant thought was practical and liberating, allowing women to run for a bus. The miniskirt, which she is most famous for, became one of the defining fashions of the 1960s. The miniskirt was also developed separately by André Courrèges and John Bates, and there is disagreement as to who came up with the idea first. Like most fashion, the short- and ever-shorter skirt was evolving already among fashion-minded young women: the designers who adapted it just helped spread the style and, in Quant's case, gave it a name. Mary Quant named the miniskirt after her favourite make of car, the Mini. She loved the car so much, she had one designed especially for her.
Quant's first collection of underwear was designed to be worn with the miniskirt look. She renamed the basics "booby traps and bacon savers" (bras and tights), which appealed to her young customers.
