New Zealand Owls

I've been doing some research on the owls I might meet on my trip to New Zealand. They have
one native owl - the Ruru or Morepork (I think it's called this because of the sound of its call.
You can see and hear more at this web address - http://www.wingspan.co.nz/morepork.html)
Here's what they look like - don't they have big, round eyes?!
