It's mentioned on this page, indeed with a meaning of "pelican":http://www.native-languages.org/hiawatha.htm
That page is part of the website that gives info on the language of Ojibwe:http://www.native-languages.org/ojibwe.htm
To me, the website looks ok, so the language info itself might be reliable; but who can be sure that this is more than an accidental correspondence? It would not be hard at all e.g. to simply invent something like "Shada" as a name, and then later find out: Surprise, surprise, that means something in some small language, with only 50'000 speakers, according to the pages given above...
