Caller ID help needed

Look in  Files/Caller.mp3

This call was brought to my attention by a friend that was hearing it after 
dark in an adjacent golf course   The golf course has many mature trees 
surrounding the play area.  The caller was near but across the road from her 
house.   She described it as very loud and frequent, about once every three or 
four seconds.

The caller had moved a few hundred yards farther away before I had a chance to 
record   I think it would turn away from me because the call was much softer at 
times.
The recording was with MD and a DIY dish using Shure 183's in a Telinga dish in 
Iowa on June 13, 2009.  The recording is marred by the sound of factories and a 
highway so I did some heavy editing in frequencies other than those of the 
caller.


I want to call it an immature Great Horned Owl but it is not quite the same as 
my reference on the Owls of NA CD.
Any ideas?  Thanks for your help.
