“Galápagos Darwin's Finches Face Deadly Avian Vampire Fly Threat, Genetic Study Reveals” — what this page in the network covers. A new genetic analysis has uncovered critical insights into the spread of the parasitic avian vampire fly (Philornis downsi), an invasive species that poses a severe threat to the iconic Darwin's finches of the Galápagos Islands. Researchers from the University of Vienna, the Charles Darwin Foundati Researchers from the University of Vienna, the Charles Darwin Foundation, and other institutions traced the fly's origins and pathways, revealing how it likely arrived via cargo ships from mainland South America.
The fly's larvae feed on the blood of nestling birds, causing high mortality rates and threatening the survival of multiple finch species, including the critically endangered mangrove finch. The study highlights the urgent need for biosecurity measures and targeted control strategies to protect this UNESCO World Heritage site.
