How is this raven related to the one in Macbeth?
This raven is croaking – the one in Macbeth is hoarse. Is it possible that this is a family of ravens who just happen to have creaky voices? Maybe a family of Carol Channing ravens? Or Bea Arthurs?
Mama Croaking Raven bellows for revenge in Hamlet while Papa Hoarse Raven announces the fatal entrance of Duncan. Baby Ravens prepare to squeak out other horrors in other tragedies to come.
