LOUISVILLE, Ky. — With a cluster of avian flu cases confirmed in Kentucky, the Louisville Zoo is taking some precautionary steps to keep its bird population safe.

The Zoo closed its public walk-through aviaries on Wednesday, according to a news release. Although none of the Zoo's birds show any signs of the disease, zookeepers are moving some birds to protected areas to avoid potential exposure.

Chilean flamingos, white storks and bald eagles will be relocated "until the threat clears." The Forest Bird Trail, African penguin exhibit, Steller's Sea Eagle Aviary and Lorikeet Landing will also be closed during that time.

“As always, our highest priority is animal safety and welfare,” said Dan Maloney, Executive Director of the Zoo. “By temporarily closing public access to the aviaries, and moving some birds to indoor areas, we will help ensure the birds’ health for as long as the situation requires."

Maloney added that the Zoo remains safe for all guests, and that the measures are intended to protect the Zoo birds. No human infections from this virus have been found in the U.S.

Avian flu can be contagious in birds and can affect several species, including domestic chickens and turkeys, both in backyard flocks and commercial flocks. Avian flu viruses can be harbored in wild waterfowl and shorebird populations.

Cases were recently confirmed in wild birds due west of Jefferson County. Currently, the disease has been detected in 12 other states, including New York, Indiana and Florida.

“We’ve been following these developments closely and have drafted a plan to minimize the risk to the Zoo’s animal collection,” said Dr. Zoli Gyimesi, Zoo Senior Veterinarian. “Closing walkthrough aviaries is prudent at this time given the recent avian influenza cases being detected in wild ducks within 50 miles of the Zoo.”

The Zoo said it will continue to monitor avian flu findings and update protocols accordingly.
