Thank you for the sites. I am exploring them.
If you have a bit more time to share, I have a couple more questions. I 
could ask them back channel if you would prefer. It is about remains of 
creatures on or about our property.

The calling we heard most recently was a great horned owl from the sounds I 
ahve been able to listen to on the computer and a Cd someone lent me. The 
shriek was telling as well. The other calls I hear I haven't heard as yet.
