Bird Flu Devastates Elephant Seal Pups in California
27 Feb
Summary
- Highly pathogenic bird flu killed over two dozen elephant seal pups.
- Avian flu outbreak marks first marine mammal cases in California.
- Seal-viewing areas at Año Nuevo state park are temporarily closed.
An outbreak of a highly pathogenic bird flu strain has significantly impacted elephant seal pups in California, resulting in over two dozen deaths. This concerning development has led to the temporary closure of seal-viewing areas at the popular Año Nuevo state park, a vital breeding ground for approximately 5,000 seals.
Researchers have identified the outbreak as the first instance of HPAI H5N1 affecting marine mammals in California. The situation is being closely monitored by teams from UC Davis and UC Santa Cruz, who are working diligently to track the spread and understand the virus's impact on the well-documented seal colony. Access to the park has been restricted through March 1st, with mandatory seal-viewing tours canceled to allow wildlife space and facilitate research.
The exact source of the virus and the reasons for the increased susceptibility of weaned pups remain undetermined. Scientists are collaborating with various wildlife organizations to monitor coastal marine mammals. The long-term consequences for the seal population and the potential for the virus to spread beyond California are still under investigation.
