Determinants of traffic mortality of Barn Owls (Tyto alba) in Friesland, The Netherlands

Collisions with vehicles can contribute significantly to overall mortality in many species. We aim to clarify causal factors affecting Barn Owl (Tyto alba) mortality along roads in the Province of Friesland, The Netherlands. Although Barn Owl road casualties have received a lot of attention in the past, relationships with food availability and road design have not been clarified. We quantified breeding densities and reproduction rates, and combined these with road casualty records and characterization of road design. We obtained 996 ring-recoveries of Barn Owls (1994-2009), all of which were f... Mehr ...
