Abstract

Road mortality of common toads (Bufo bufo) near a breeding site, 1974-1994 Arnold S. Cooke English Nature, Northminster House, Peterborough PE1 IUA, UK Mortality of common toads (Bufo bufo) on roads near a breeding site in Ramsey, Cambridgeshire, England was described by Cooke (1988) for the period 1974-1988. Counting dead toads on a single date at peak season has continued up to 1994, giving 21 1 years of results. The number of toads counted will be a proportion of the total killed in any year. Whether the proportion varies from year to year, in response to weather conditions for instance, is not known. Although scavengers, such as corvid birds, can rapidly remove dead toads from roads in rural areas (Slater, 1994), corvids have never been seen feeding on carcases at this suburban site. Toad carcases that escape being flattened by road traffic often dry and mummify, persisting for weeks after death. The proportion of the population that is killed each year will vary depending on the proportion of the population trying to cross roads, the volume of traffic and the activities oflocal conservationists who have recently carried numbers of toads across the roads (Cooke, 1988).
