Birdsbesafe: Is a novel cat collar more effective at stopping domestic cats from killing birds at higher latitudes?


February 2019 - February 2022


Up to 4 billion birds are killed annually in the US alone by domestic cats. We examine a novel conservation tool that has the potential to be effective at keeping domestic cats from killing songbirds: the Birdsbesafe® cat collar cover. We are testing whether the BCC is differentially effective at various latitudes. Because birds at higher latitude birds have a shorter breeding season and a concurrent higher spike in testosterone then birds at lower latitudes, we predict that the more "distracted" breeding birds in the northern latitudes will show a higher magnitude difference in predation by cats with and without the BCC.
