At the moment results are only available in yearly reports to the funder and in the Project newsletter (http://www.labor.uevora.pt/index.php/pt/projecto-tytotagus-downloads).
Although focused on Barn Owls, the project also collects data for other owl species (Little Owl, Tawny Owl, Eagle Owl, Long-eared Owl, Short-eared Owl) - e.g. collection and analysis of carcasses/pellets, breeding data, transect counts.
