several weeks ago one green cheek conure of a pair in a topper cage was observed in the late afternoon after a normal morning to to have shallow rapid breathing through the mouth, though the nostrils/Ceres seemed to be clear. After picking up the bird, the bird seemed to have no strength, and was laying on its back beak open. After only a few minutes the bird gave several audible grunts and died.
Any ideas as to what might have happened? The companion green cheek continues to be healthy.
