I prefer not to walk in the woods at night with my parabolic and that 
seems to be when I enter for deer.  It is a pain.  For deer and for 
stalking I pickup my shotgun mic.  But the types of sounds you are 
after you may prefer a omni.  Keep in mind your minidisc recording in 
mono is 160 mins.  You can locate the prime location setup in a tree  
and leave.  That likely will get you better results.

A salad bowl can be used to achieve a 45 degree viewing angle but is 
not a parabolic.  Consider it more like a shield for back noise if 
you want to use one.

The Telinga dish and other good parabolics have to have their mold 
made from a computer manufactured model.  My dish seems to have a 5 
degree viewing angle and maybe Klas will tell us exactly what his is 
designed as, but it seems to be a bit more friendly and around 15 
degrees. 

Keep in mind what you lack in equipment right now you can make up for 
with the experience you have from spending time in the field.  Since 
I've been recording my stalking and tracking skills have improved 
many fold.
