My Quaker Niki passed this morning. He was 25 1/2. I had him the entire time. He had a myriad of issues. He broke his wing in 2016 and recovered. He developed a heart problem in 2018 and was on 3 heart medications since then. He had broken his leg in August and recovered. Almost died in November from heart problems and fluid in his lungs, but he recovered. He was doing remarkably well since then except for bad arthritis in his feet. This morning he was preening and fell from the top of the cage onto the carpet. When I picked him up i knew it was bad. He appeared to have trouble breathing. He died in about a minute in my hand. Now I feel lost.
So sorry about the loss of your QP Niki. Many of us here know the pain of losing a much-loved companion parrot. Niki had a good long life with you, and you certainly gave him good care. As difficult as it is for you now, in time you'll be comforted by all the good memories of the many years you had with Niki.
I understand exactly what you mean about a quiet house. When my Amazon George passed away (after 40 years with my family) it was much too quiet, and my routine was disrupted. I was accustomed to making George's breakfast while my morning coffee was brewing. Without that to do, I felt lost in the morning. Time does heal, and Niki will always be with you, in your heart and thoughts.
