Road Casualties among Birds

A national enquiry into the high mortality of bird life on British roads is recommended along prescribed lines and the use of cycles rather than cars for more satisfactory observation is discussed.Observations made on foot are also highly accurate.2. Comparison is made from limited figures between British, French and American roads and the first, with their frequent changes of direction and close cover, are shown to be more lethal.3. The high mortalities of House Sparrow, Blackbird and Song Thrush are examined in more detail, and some reasons for the spread of casualties are discussed.4. Some of the uses of roads to birds are discussed.5. Some examples of bird behaviour on roads are described.
