A glance at the diagram provided reveals the number of wild birds, namely, coastal, woodland and farmland species which had settled in an area from 1970 to 2004. Looking at the overall perspective illustrates; the number of birds witnessed a dramatic increase. Farmland birds had been over the other types, however; most of the time coastal species had taken last place throughout of the period.
The data illustrates, at the outset of the period, all types of birds had been near in terms of quantity of population between 1970 and 1979. Then suddenly they experienced a sharp decrease in close 1977 until 1979 were reduced by approximately in average of 12. Although coastal birds continued this promise, up to end and reached to under 60, the others type changed their trends over the duration of study.
The second point of rising for farmland and woodland bird is related to 1979, which they surged to over 105 and just under 110 respectively in 1980. Despite fluctuation in their trends, ultimately woodland accepted failure. Therefore, by over 110 and under 90 farmland and woodland had taken first and second place respectively.
