I don't own a telinga but have played with it.  Mine is a bigger dish
that has all of the problems of a telinga and a few (more/less)
differnt ones.

I would recommend that Klas and anyone using a dish put a "site" on
it for aiming.  It can be as simple as a bent wire on a spring paper
clip.  The problem comes in monitoring with headphones and recording
at the same time.  A site helps a lot in getting certain you are on
center with a stereo parabolic.

Many recommend a good set of headphones when recording.  I don't.  I
recommend the cheap, in the ear, sony consumer model.  This is
because I know I have quality when recording and what I want is to
know when I am on max target. I use my eyes to set record level not
my ears. I put the headset at the back of my ears so that my natural
hearing is not effected.  When I am "on target" I can hear some
additional sound comming from the headphones (located behind my ear
canal) because of the high additional gain when you are on the
narrow "target" line with a parabolic.  I am then paying attention
to "target" and location of "off target" callers.  This is what I use
for not getting lost in complex sound fields.  The good headphones
are needed for edit and review but for me have no place in making
good recordings.

As far as id's of birds while recording and behavior, you will learn
to know behavior and species identification more fully than
a "lister" with practise just because you are recording.  This stuff
is not easy and the more you record the more you will know.

I strive to edit as little as possible.  Different end uses have
different edit requirements so I can not go there from this post.
On my recent post "day" was edited only for rumble under 150 cycles
where nothing called and a curve reduction from 150 to 1200 at about
6db.  "Moose" was not edited as it is "techno-garbage".  "Night" was
only equalized for volume and if I was to post it again I would not
have.

On the other question on my post.  These particular recordings were
done with an old consumer minidisc recorder and two Sennheiser ME-62
microphones.  In "day" I mounted the mics in a homemade barrier for
stereo separation and the other two the mics were spaced in a Greg
Clark parabolic (1st prototype).
