Behind the scene
There is a third perching bird lineage, the Acanthisitti from New Zealand , of which only two species remain alive today. The song in this clade is essentially territorial, because it communicates the identity and whereabouts of an individual to other birds, and also signals sexual intentions. Sexual selection among songbirds is highly based on mimetic vocalization. Female preference has shown in some populations to be based on the extent of a male's song repertoire. The larger a male's repertoire, the more females a male individual attracts.
While almost all living birds give calls of some sort, well-developed songs are only given by a few lineages outside the songbirds. Other birds especially non-passeriforms sometimes have songs to attract mates or hold territory, but these are usually simple and repetitive, lacking the variety of many oscine songs.
The monotonous repetition of the common cuckoo or little crake can be contrasted with the variety of a nightingale or marsh warbler. On the other hand, although many songbirds have songs that are pleasant to the human ear, this is not invariably the case.
Many members of the crow family Corvidae communicate with croaks or screeches, which sound harsh to humans. Even these, however, have a song of sorts, a softer twitter that is given between courting partners. And even though some parrots which are not songbirds can be taught to repeat human speech, vocal mimicry among birds is almost completely restricted to songbirds, some of which such as the lyrebirds or the aptly-named mockingbirds excel in imitating the sounds of other birds or even environmental noises.
As a result, song can vary even within a single species. Many believe that song repertoire and cognition have a direct relationship. However, a study published in has shown that all cognitive ability may not be directly related to the song repertoire of a songbird. Specifically, spatial learning is said to have an inverse relationship with song repertoire.
So for example, this would be an individual who does not migrate as far as others in the species, but has a better song repertoire. This suggests an evolutionary trade-off between possible alleles. With natural selection choosing traits best fit for reproductive success there could be a trade off in either direction depending on which trait would produce a higher fitness at that time period.
Song repertoire can be attributed to male songbirds as it is one of the main mechanisms of courtship. Song repertoires differ from male individual to male individual and species to species. Some species may typically have large repertoires while others may have significantly smaller ones. Mate choice in female songbirds is a significant realm of study as song abilities are continuously evolving. Currently there have been numerous studies involving songbird repertoires, unfortunately, there has yet been concrete evidence to confirm that every songbird species prefers larger repertoires.
A conclusion can be made that it can vary between specific species on whether a larger repertoire is connected to better fitness. With this conclusion, it can be inferred that evolution via natural selection, or sexual selection, favors the ability to retain larger repertoires for these certain species as it leads to higher reproductive success.
The better the mimicking ability, retaining ability, and the quantity of other species mimicked has been proven to have a positive relationship with mating success. Female preferences cause the constant improvement of accuracy and presentation of the copied songs. Sibley and Alquist divided songbirds into two " parvorders ", Corvida and Passerida standard taxonomic practice would rank these as infraorders.
Subsequent molecular studies, however, show this treatment to be somewhat erroneous. Passerida is a broad lineage, including over one third of all bird species Passerida species in . These are divided into three major superfamilies though not exactly corresponding to the Sibley-Ahlquist arrangement , in addition to some minor lineages. The bulk of these form the large superfamily Corvoidea species in  , which is a sister group to the Passerida.
The remaining 15 Oscine families species in  form a series of basally branching sister groups to the Corvoid - Passerid clade. By the s the gaols of England were so full that convicts were often chained up in rotting old ships. The government decided to make a settlement in New South Wales and send some of the convicts there. In the First Fleet of eleven ships set sail from Portsmouth carrying convicts, sailors, marines, a few free settlers and enough food to last for two years.
Their leader was Captain Arthur Phillip. They were to make a new colony at the place that Captain Cook had discovered, named Botany Bay because of all the unknown plants found there by the two scientists. Captain Phillip found that Botany Bay was flat and windy. There was not much fresh water.
He went with two ships up the coast and sailed into a great harbor which he said was "the finest harbor in the world! For the first few years of the settlement, things were very difficult. No-one in the British Government had thought very hard about what sort of convicts should be sent to make a new colony. Nobody had chosen them carefully.
There was only one man who was a farmer. There was no-one among the convicts who was a builder, a brick-maker or a blacksmith.
No-one knew how to fix the tools when they broke. All of the cattle escaped. There were no cooking pots. All the plants were different so no-one knew which ones could be eaten. It was probable that everyone in the new colony would die of starvation.
Somehow, the little group of tents with a hut for the Governor, Arthur Phillip, and another hut for the supply of food, grew into a small town with streets, a bridge over the stream, a windmill for grinding grain and wharves for ships. By the s there was a fine brick house for the Governor. There was also a hospital and a convict barracks and a beautiful church which are still standing today.
Settlements had spread out from Sydney, firstly to Norfolk Island and to Van Diemen's Land Tasmania , and also up the coast to Newcastle, where coal was discovered, and inland where the missing cattle were found to have grown to a large herd. Spanish Merino sheep had been brought to Sydney, and by , farmers were raising fat lambs for meat and also sending fine wool back to the factories of England.
While the settlement was growing in New South Wales, it was also growing in Tasmania. The climate in Tasmania was more like that in England, and farmers found it easy to grow crops there. Because Australia is such a very large land, it was easy to think that it might be able to hold a very large number of people.
In the early days of the colony, a great number of explorers went out, searching for good land to settle on. When the settlers looked west from Sydney, they saw a range of mountains which they called the Blue Mountains. They were not very high and did not look very rugged but for many years no-one could find their way through them.
In Gregory Blaxland , William Lawson and a year-old called William Charles Wentworth crossed the Blue Mountains and found land on the other side which was good for farming. Some people, like Captain Charles Sturt were sure that there must be a sea in the middle of Australia and set out to find it. Many of the explorers did not prepare very well, or else they went out to explore at the hottest time of year. Some died like Burke and Wills. Ludwig Leichhardt got lost twice. The second time, he was never seen again.
Major Thomas Mitchell was one of the most successful explorers. He mapped the country as he went, and his maps remained in use for more than years. He travelled all the way to what is now western Victoria, and to his surprise and annoyance found that he was not the first white person there.
The Henty brothers had come from Tasmania , had built themselves a house, had a successful farm and fed the Major and his men on roast lamb and wine. The gold rushes of New South Wales and Victoria started in leading to large numbers of people arriving to search for gold. The population grew across south east Australia and made great wealth and industry.
By the gold rushes had made some poor people, very rich. The transportation of convicts to Australia ended in the s and s and more changes came.
The people in Australia wanted to run their own country, and not be told what to do from London. The first governments in the colonies were run by governors chosen by London. Soon the settlers wanted local government and more democracy. William Wentworth started the Australian Patriotic Association Australia's first political party in to demand democratic government.
In , the city councils started and some people could vote. New South Wales Legislative Council had its first elections in , again with some limits on who could vote. In , the right to vote was given to all men over 21 in South Australia. The other colonies soon followed.
Women were given the vote in the Parliament of South Australia in and they became the first women in the world allowed to stand in elections. Australians had started parliamentary democracies all across the continent. But voices were getting louder for all of them to come together as one country with a national parliament.
Until , Australia was not a nation , it was six separate colonies governed by Britain. They voted to join together to form one new country, called the Commonwealth of Australia, in Australia was still part of the British Empire , and at first wanted only British or Europeans to come to Australia. But soon it had its own money, and its own Army and Navy.
In Australia at this time, the trade unions were very strong, and they started a political party, the Australian Labor Party. Australia passed many laws to help the workers. In , the First World War started in Europe. Australian soldiers were sent to Gallipoli , in the Ottoman Empire.
They fought bravely, but were beaten by the Turks. They also fought on the Western Front. More than 60, Australians were killed. Australia had a really hard time in the Great Depression of the s and joined Britain in a war against Nazi Germany when Hitler invaded Poland in But in lots of Australian soldiers were captured in the Fall of Singapore by Japan.
Then Japan started attacking Australia and people worried about invasion. But with help from the United States Navy , the Japanese were stopped. After the war, Australia became a close friend of the United States. When the war ended, Australia felt that it needed many more people to fill the country up and to work. So the government said it would take in people from Europe who had lost their homes in the war.
It did things like building the Snowy Mountains Scheme. Over the next 25 years, millions of people came to Australia. They came especially from Italy and Greece , other countries in Europe. Later they also came from countries like Turkey and Lebanon. An important new party, the Liberal Party of Australia was made by Robert Menzies in and it won lots of elections from until in , then Gough Whitlam won for the Labor Party.
Whitlam made changes, but he made the Senate unhappy and the Governor-General sacked him and forced an election in Then Malcolm Fraser won a few elections for the Liberal Party.
In the s many people began coming to Australia from China , Vietnam , Malaysia and other countries in Asia. Australia became more multicultural. In the s and s Australia became one of the richest countries in the world, helped by mining and wool. Australia started trading more with America, then Japan. Australia supported the United States in wars against dictatorships in Korea and Vietnam and later Iraq.
Australian soldiers also helped the United Nations in countries like East Timor in In , the famous Sydney Opera House opened. In the s, 80s and 90s lots of Australian movies , actors and singers became famous around the world. In the year , Sydney had the Summer Olympics. Australia had a bad recession in , but when other Western countries had trouble with their economies in , Australia stayed strong.
Today Australia is a rich, peaceful and democratic country. But it still has problems. A lot of land in Australia like Uluru has been returned to Aboriginal people, but lots of Aborigines are still poorer than everybody else. Every year the government chooses a big number of new people from all around the world to come as immigrants to live in Australia. These people may come because they want to do business, or to live in a democracy, to join their family, or because they are refugees.
Australia is made up of five states and two mainland territories. Each state and territory has its own Parliament and makes its own local laws. The Parliament of Australia sits in Canberra and makes laws for the whole country, also known as the Commonwealth or Federation. The Federal government is led by the Prime Minister of Australia , who is the member of Parliament chosen as leader. The current Prime Minister is Scott Morrison.
Australia was colonised by people from Britain ,  but today people from all over the world live there. English is the main spoken language, and Christianity is the main religion, though all religions are accepted and not everybody has a religion. Australia is multicultural , which means that all its people are encouraged to keep their different languages, religions and ways of life, while also learning English and joining in with other Australians.
Famous Australian writers include the bush balladeers Banjo Paterson and Henry Lawson who wrote about life in the Australian bush. In , Patrick White won the Nobel Prize in Literature , the only Australian to have achieved this; he is seen as one of the great English-language writers of the twentieth century.
Australian Aboriginal music is very special and very ancient: Australia has two public broadcasters the ABC and the multi-cultural SBS , three commercial television networks, three pay-TV services, and numerous public, non-profit television and radio stations. Each major city has its daily newspapers, and there are two national daily newspapers, The Australian and The Australian Financial Review.
Australian movies have a very long history. Australia is also a popular destination for business conferences and research, with Sydney named as one of the top 20 meeting destinations in the world. Sport is an important part of Australian culture because the climate is good for outdoor activities. Local popular sports include Australian Rules Football , horse racing, soccer and motor racing.
Australia has participated in every summer Olympic Games since , and every Commonwealth Games.
