Health authorities are trying to find out what poisoned at least 20 condors in the Andes mountain range between Chile and Argentina.
The huge endangered birds, with a wingspan of up to 3m, were found near the town of Los Andes, about 80km east of the Chilean capital, Santiago.
The authorities say two birds died, but 18 are recovering at a clinic.
Mauricio Fabry, director of Metropolitan Zoo, told reporters the birds were showing "signs of intoxication".
