Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy. Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory. Do you know what a 'territory' is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger enter your territory and threaten you, you may shout. Probably this is enough to frighten him away. If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird's song, and it is usually enough to keep an outsider away. Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language of their own. Most of it has something to do with attracting mates and setting up territories. Question: Why do birds keep on singing at nesting season? Answer:

Article: Reading for pleasure is declining among primary-age pupils, and increasing numbers of "time poor" parents are dropping the practice of sharing bedtime stories with their children once they start school. Research presented to a conference last week found that, while parents read to preschoolers, this later tails off, and by the final year of primary school only around 2% read to their children every day. Once children can read skillfully, parents tend to step back, and this usually happens at the age of seven or eight. The report also found that 82% of teachers blame the government's "target--driven" education policies for the fact that fewer children are reading for pleasure. They believe that a straitjacket of strictly organized schooling is containing young people's ability to read more widely. Two-thirds of teachers surveyed said they lacked time in the school day to introduce a variety of books and that this was a "major obstacle to being able to develop a level of reading". Teachers also cited as main factors the reduction in the number of school librarians, who could put interesting books before children, and the rise in "screen time", switching children from reading to playing games. The majority of teachers said the curriculum's " emphasis on reading as a skill to be mastered" was increasing the pressure. This was _ by parents who saw reading just as a focus of learning, a skill critical to career advancement in a competitive world. Reading habits and the digital revolution in publishing were key topics of debate at the conference. The theme of the lack of British culture was supported by children's writer Frank Cottrell Boyce, who wrote the scripts( ) for the opening and closing ceremonies of the 2012 Olympics. "We discovered the whole nation had forgotten that they did the industrial revolution," he said. "Books are so central to it; books can be written by anyone. A lot of the pleasure of a book is listening to somebody read it to you. " "We found a real love of reading among teachers, and a... Question: It can be inferred from the article that _ . Answer:
