Two animals at Lincoln Park Zoo in Chicago, a young Chilean Flamingo and a 7-year-old Harbor Seal, died from avian influenza, prompting the closure of the bird house to protect remaining wildlife.

The recent deaths of a Chilean Flamingo named Teal and a Harbor Seal named Slater from highly pathogenic avian influenza (HPAI) have raised concerns at Lincoln Park Zoo, leading to the temporary closure of its bird house. This outbreak underscores the virus’s potential impact not only on bird populations but also on some mammal species, highlighting the importance of ongoing conservation efforts and preventive measures to protect wildlife from communicable diseases.

The fatal incidents occurred on January 8 and January 9, 2025. Teal, the Chilean Flamingo, was notably young, having only been a few months old and just beginning to acclimate to the zoo environment. Slater, the Harbor Seal, was well-known among visitors for his playful and inquisitive nature, which makes the loss particularly poignant for both zoo staff and regular patrons.

In light of this outbreak, Lincoln Park Zoo has implemented a precautionary measure by closing its bird house for an undetermined period. This decision aims to protect the remaining animals from potential exposure to the virus. The zoo is taking comprehensive steps to safeguard its inhabitants and limit the risk of further infections, highlighting a proactive approach during this health crisis.

The zoo has established a response plan that includes the use of personal protective equipment for staff and measures designed to prevent cross-contamination between different animal species. This structured response is driven by the recognition that HPAI spreads primarily through the saliva, nasal secretions, and feces of infected birds. The zoo's veterinary team is closely monitoring the situation and assessing other animals for any signs of illness.

Dr. Kathryn Gamble, a leading expert at the zoo, commented on the nature of HPAI, noting that while it is a naturally occurring virus typically found in free-ranging waterfowl, it has also shown susceptibility in several mammal species. This development emphasizes the need for heightened awareness and vigilance in wildlife care and management.

Despite the concerning situation, officials have emphasized that zoo visitors are not at risk of contracting the disease from the animals housed at the facility. The zoo’s management takes the health and safety of its visitors seriously and assures the public that all necessary precautions are being undertaken to prevent any potential spillover of the virus.

Seth Magle, a wildlife expert, has reiterated the necessity for the public to keep pets away from wildlife, especially during avian flu outbreaks. This advice is particularly relevant given the recent cases and the general nature of HPAI’s transmission pathways.

Director of Veterinary Services, Lester E. Fisher, expressed sadness over the loss of both animals, underscoring the personal impact such events have on zoo staff who care for the animals. 'Each animal in our care holds a special place in our hearts, and the loss of Teal and Slater is deeply felt by everyone at Lincoln Park Zoo,' he stated.

As the zoo navigates through this outbreak, it remains committed to monitoring its ecosystem and ensuring that all animals receive the best possible care during this challenging time.
