I can't believe no one will help you! Contact your local newspaper and maybe try and get it publicized that no animal association will assist you. People here who find wildlife always do that around here and then people help out.

I was searching the net and it said that hatchling Sora's eat canned dog food.. but when I clicked the link, it told me I needed to subscribe (for $40 ) so I'm not sure if older ones can eat it or not..

Also, try out this Wildbirds forum.. http://www.wildbirds.com/forums/
