I called, and they advised me to bring him in and they could euthanize him. Uh ... no. Not knowing the extent of his injuries, I couldn't do that. So I drove home and placed him in my back garden. I gave him some water, cooked rice and sunflower seeds. I have no idea if any of that interests him, but I hope it will tide him over until I figure out what to do.
I might call the OSPCA because they do take in wildlife, but considering what's been happening there lately, they might be a little too busy (more on that in a later post, but you can read a bit about it in the May 2010 posts on my other blog.) When I went out to take this photo (click to enlarge), I frightened him, and he flew into the cedar hedge, then bounced off. At least he's able to fly now, so perhaps he just needs some time to rest.
Update: The investigators have taken the duck away. I do hope they find he's just a little dazed, and he'll soon be back with his family. Hmm ... I must find out how and where they release ducks after they've been rehabilitated. I suppose, with all his natural duck homing instincts, he shouldn't have a problem. Should he?
