PITTSBURGH — The National Aviary announced some “waddle-ful” news on Wednesday.

Two additional African Penguin chicks hatched in early February, which Aviary officials say marks “another incredible step towards saving the newly up-listed Critically Endangered species from the brink of extinction.”

The first chick hatched on Feb. 7, followed by its younger sibling on Feb. 10. Both chicks continue to “grow and thrive” in a behind-the-scenes habitat.

These chicks are the 11th and 12th hatched by parents Bette and Sidney.

The Aviary will continue to post updates on the new additions to the flock on its website.
