We recently had a few casualties concerning our canaries. We were given a pair of canaries from a friend of ours who breeds all kinds of birds and he had come to visit them several times and thought they were doing marvelously. My grandmother has been taking care of them mostly because she lives with us and when I am away at school she is very careful to make sure they have food and water and that the cage is covered with a towel at night. A few weeks ago our male canary died and we thought it might have been because of the temperature. At our house at this time of year it is very warm in the day, but but dipping to 50 F at night and the canaries live near a large window that is always closed except for maybe four inches at the top but this is very far from them so they are not in a draft. And as her mate had died I was worried that the female would be lonely so we were looking into getting her a friend. In the mean time I have been trying to spend time with her so she would not be lonely, but she was so wild I could not even get her out of the cage and recently she died as well. Not only is this very sad, but very confusing because I do not know what we did wrong. We have had birds for as long as I can remember and all those birds have done very well. We had a lovely budgie for years and he loved people which was actually his downfall because he was sitting on my dad's shoulder while he worked on the pipes under the sink and went outside forgetting the bird was there and he flew away. And our parrolet got out of the cage through a small opening and flew into the window when I had been gone for a few weeks. So mostly our birds are healthy and long living except for fluke accidents. One thought that occurred to me was that the birds were older than we thought. Does anyone have any ideas about what happened? Thank you!!
