Seroepidemiologic Survey of Potential Pathogens in Obligate and Facultative Scavenging Avian Species in California. [PDF]

open access: yesPLoS ONE, 2015
Throughout the world, populations of scavenger birds are declining rapidly with some populations already on the brink of extinction. Much of the current research into the factors contributing to these declines has focused on exposure to drug residues ...
