The infected goose, part of a rare and threatened species, was found deceased in an off-exhibit area of the zoo earlier this week.

The Woodland Park Zoo in Seattle is taking extra precautions after a confirmed case of the avian flu, according to a news release.

A red-breasted goose at the Woodland Park Zoo has died from the first suspected case of Highly Pathogenic Avian Influenza (HPAI), the zoo announced Thursday.

Woodland Park Zoo is ramping up safety measures after a red-breasted goose died in what is the zoo’s first suspected case of Highly Pathogenic Avian Influenza (HPAI), or bird flu. The goose, a rare and threatened species, was found dead earlier this week, and preliminary tests received on Nov. 14 resulted in a positive result for HPAI.

Pending confirmatory testing, this would mark Woodland Park Zoo’s first case of bird flu, a viral infection carried by wild birds such as waterfowl. Bird flu is primarily spread through respiratory secretions and bird-to-bird contact, according to the zoo.

Test results confirmed that avian flu killed a rare bird at the zoo which is taking precautions to protect other birds.
