The graph shows the bird population in Europe, measured in millions, for the years 1977 to 2001, in three-yearly intervals. Overall, the graph shows the population decreased over time. In 1977, the population was 120 million birds. This increased to a peak of about 126 million in 1980, and then dropped sharply over the next six years to approximately 98 million in 1986. It then rose significantly to about 112 million in 1989. It fell sharply over the next three years to about 95 million in 1992 and remained relatively stable after that at between 96 and 90 million birds. The graph shows a trend of a gradual decrease in the number of birds since 1995.
