The hardest part of making this comic was coming up with the spelling of the sounds ravens make. They don’t caw like crows, but instead do this incredible mixture of a honk, bark, cry, trill… thing. Look it up. They’re awesome, but I have no idea how to spell the sound phonetically. If you can think of a better spelling, throw it into the comments.
I came pretty close to deciding this raven was a mute, though, just to make it easier on myself.
Please excuse the ignorance of an older man. How may I turn on the sound of the Raven croak?
It took me some time to find it myself, but youtube has a number of video examples.
