AKRON, Ohio — The Akron Zoo said it's taking extra precaution of its birds as cases of highly pathogenic avian influenza, also known as bird flu, have been detected in Ohio and across the nation. 

The zoo said it has temporarily moved many of its birds indoors to keep them safe during this time. 

"We know you love our feathered friends as much as we do. The health and welfare of our birds is our top priority," Akron Zoo wrote in a Facebook post. "They will all return to their outdoor habitats as soon as the risk of exposure is low."

Ohio currently leads the nation in bird flu cases confirmed in commercial flocks, according to the U.S. Department of Agriculture. In the past 30 days, 25 commercial flocks in Ohio have been affected. The last detection of the disease in the state was on Jan. 27. Additionally, there have been 11 confirmed cases of wild birds in the Buckeye State.

Nationally, in the past 30 days, there have been 113 confirmed cases in flocks. 

Current cases of the bird flu in Ohio and the U.S. can be tracked using the WHISPers system, which can be found here.

According to the Ohio Department of Natural Resources, birds may exhibit the following symptoms if affected by bird flu:

• Decreased egg production

• Swelling of the head, eyelids, comb, wattles and hocks
• Nasal discharge
• Lack of coordination
