PORTLAND — Oregon Zoo officials in Portland say after a week of antibiotics and a blood transfusion from an adult condor, an endangered California condor chick has turned the corner and is getting stronger.

PORTLAND — Oregon Zoo officials in Portland say after a week of antibiotics and a blood transfusion from an adult condor, an endangered California condor chick has turned the corner and is getting stronger.

Zoo staff have worked feverishly this month to hatch the underweight and shell-bound bird. Monitoring the egg at the zoo’s Jonsson Center for Wildlife Conservation, keepers determined it would not be able to hatch alone.

Fearing the chick would suffocate, they stepped in and helped — a worst-case scenario for them. Keepers broke away part of the shell and removed the chick.

Condor Curator Shawn St. Michael and condor keepers provide around-the-clock care.
