IDENTIFICATION ESSAY
The following four photographs, © by Flavio Quintana and Yorio Pablo, were taken at Punta León, Chubut, Argentina, in November 2000.
Note the orange-tinged base of bill in lower bird and the positioning of the gonys near base of bill in top bird and near middle of bill in lower bird. According to Flavio Quintana, "I saw few individuals with bright orange bills but unfortunately we don't have any pictures."
