There is at times too much analysis to the instruments we use in the
field, I agree you need to know most of the fundamentals but what I
always do and continue to do is test whatever I use in the field,
sometimes you can get flooded with all the benchmarks, sonograms, blah,
blah, blah. When I take recording gear out with me, I make sure I have
all my mics at my disposal. Most of the time I will test the
environment through all mics with headphones on to get what I=1B$B!G=1B(Bm =

I guess that this phenomenon is caused by the infrasound-rejection
filter that is implemented in the MKH shotguns (Sennheiser added
that filter in order to reject the inherent sensitivity of shotguns
to infrasound). They specify a cutoff frequency of 50 Hz. As it can
be seen from your sonogram, the maximum energy of the grouse sound
is below 50Hz. It seems, that the Telinga does not have such an
internal high-pass filter and is therefore able to pick up these low
frequencies. But the dish should have no significant effect at those
frequencies.
