It's a great joy when everything succeeds and our wards return to normal life. This guy got into the fuel oil. How it did it will remain a mystery. This situation is dangerous not only because the plumage suffers a lot, but also from severe intoxication. It took more than a year before it completely changed its plumage and recovered.
Now it's time to say goodbye. This is an adult bird that does not need special adaptation, it knows how to live independently. I opened the enclosure and left it in case it wants to come back. Here it is always waiting for a delicious lunch and care.
