Animals may escape and die away from the road after the collision, rebound off the road or retain by vehicle. In these cases, it is so extremely difficult to be recorded through typical roadkill surveys. The study has been carried out by the Doñana Biological Station within the SAFE project to assess wildlife mortality on Spanish roads

Although roadkill studies on a large scale are challenging, they can provide valuable information to assess the impact of road traffic on animal populations. Over 22 months, 45 road sections of 10 km within a global biodiversity hotspot in Andalusia, in southern Spain, were surveyed. The region was divided into five ecoregions differing in environmental conditions and landscape characteristics and the relative magnitude, composition and spatiotemporal patterns of vertebrate (birds, mammal,...

One of the most critical phases in the life of petrels is at fledging when young birds pass from parental dependence on land to an independent life at sea. To mitigate mortality at this time, rescue programs are implemented near breeding sites around the world, especially for birds grounded by artificial lights. This study evaluated the plumage and body condition of short-tailed shearwater fledglings captured at colonies just before departure in comparison to fledglings washed up on beaches...
