There are a lot of birds in my area. There are a number of reasons for this. Firstly, we have a great many hedges in this area, many of them hawthorn, a wonderful protection for small birds. Secondly, we have a lot of trees of all shapes and sizes, so other tree dwelling and tree roosting birds are accomodated. Thirdly, we do not have huge areas of intensive agriculture going on near us.
Insecticides mean less pests and ultimately less birds.
Crows Around here crows, like foxes, are appreciated as a natural part of the environment. In many farming areas both are seen as pests, to be exterminated so that they do not threaten stock or crops. Only by appreciating animals and birds rather than competing with them can we hope to keep them alive. Here is a picture of what may be - a nightmare picture. The roads were packed nose to tail with cars, each belching out noxious fumes both visible and invisible.
