Well I am so devastated upon realizing that an accident caused the death of my almost 4-year old green cheek, Mango. About 2 weeks ago he went missing, and I posted that I thought he flew away. After getting over the initial shock of him not being here, I now realize what actually happened. About 2 months prior to him missing, he got himself into an accident with his cage; he flew so hard into it that we believe that he wedged his head in between the rails, and when we found him he was on his perch but bleeding. We noticed that his eye was injured and bleeding around his beak. We helped him over the next few days by keeping the eye clean and keeping him comfortable. We called a vet which told us that’s about all we could do. But he couldn’t eat properly, so we made sure he drank and ate what he could. About a month later he was eating fine, the eye was healing and he was flying fine. Then aggressive behaviour started, biting, attacking people when they entered the room if he didn’t know them, and lots of nesting and regurgitating. All over everything. We figured it was hormonal and would pass. Then he found a dark place to go and hide all the time. The next thing we knew he had disappeared. No clues, nothing, just a hole in the floor of my husband’s hobby room which we figure he slipped down and died due to wanting to be alone. He was sick from his accident and we didn’t realize it! We thought it was hormones. I am sick with guilt, we loved him and it is too late to repair this. We cannot get under the house as the opening is way to shallow, so he died and decomposed down there by now. I am horrified and not sure how to move forward. We did not know enough bout bird behaviours. We did not educate ourselves well enough, and the more I read, the more I see how I did everything wrong. But he was loved while he was with us. How do I move on from this guilt. And I miss him so much. Cannot stop crying.
