Dear Sunetro,
There is a very substantial body of information on the truly significant relationship that Native Americans have with the Corvids (especially the Raven).  I do not have specific stories and beliefs here, but would kindly suggest that you first do some Google searches on this relationship, and then follow up with some queries to websites for individual tribes (both USA Tribes and Canadian First Nation peoples). 

Sorry I can not be of more specific help to you..... but, I hope you well with your query. 
Strigologically yours,

David
