An eight-year-old red-breasted toucan (Ramphastos tucanus) was presented for a post-mortem. The bird had been in the collection for 5 years; it was an aviary bird whose mate appeared healthy. The bird was clinically normal the previous day. On external examination, no abnormalities were noted and the body weight was considered good at 435g.
| Question | Answer | Article | |
| What is the most likely diagnosis? | The most likely diagnosis is iron storage disease (haemochromatosis).
Cellular damage may or may not result from excessive iron deposition. Organ dysfunction and clinical illness or death may be the result. It is common to have a bird that appears clinically healthy prior to acute death. |
