regarding the sound of crows in Australia...

Page 60:
"The cawing of a crow directly above broke the stillness at last.
  'Agnes ... that sounds like Crow from Manitoba.' We stood up.    ...
  'That's Willy-D the mascot of our village." The large crow flew down
and landed on Ginevee's shoulder. He had a bubble gum wrapper in his beak.
  'Agnes, are you sure that's not Crow?'
  'You seen one crow, you've seen them all." Agnes giggled and patted my back.
'Crow is powerful, but even he would have trouble flying thousands of miles.'

Page 219:
"I hadn't seen Willy-D in several days  ...  He sounded like I felt.  ...
The crows in Australia sound different than crows do anywhere else I've ever
been. They sound like yowling cats as they croon and lament."
