Tom,

I read What An Owl Knows also and it’s a great book!  Packed with valuable info.  Like the fact that female and male burrowing owls migrate in different directions (males go north and females go south) and why that might be.  Also, the studies by Denver Holt, a retired heart surgeon but dedicated owl researcher, are so intriguing!  It’s one I will refer to time and time again.
