Doug and Sheila Carrick, the Hornby Eagle Group and friends, are shocked and saddened to report the sudden collapse and death of our beloved Phoenix. A rescue effort was underway, but his decline was sudden and swift. We ask that you remember him by supporting the work of the Mounainnaire Wildlife Rehabilitation Center (http://wingbeats.info/), who would have moved heaven and earth to help. We love you Phoenix, and we mourn with Mom and Dad Hornby.
