Let's note something. The mic will be just as good with the dish. In
fact, it will be better. There will be some gain even at that low level.
This is certainly the case with the current Telinga Pro V. It picks up
low frequencies, With Gain. Removing the mic from the dish lowers the
gain at low frequencies. I verified this today on random low frequency
stuff outside (including doves). I know the Telinga Pro V picks up owls
very well as I record distant owls incidental to my frog recordings.
Let us look at the shotgun mic. A shotgun mic gives you no gain
advantage over a omni. It has a interference tube which attenuates the
off axis sound, but on axis it's a regular mic in a tube, no extra gain
compared to a regular mic of the same sensitivity. You use a shotgun
mic to narrow the pickup field, not for increased reach. You then get
some gain by amplifying the mic output (including amplifying it's self
noise)
Combine those two, and what you get is that even at low frequencies if
the mic capsules have the same sensitivity you will do better with the
parabolic than with a shotgun for reach.
My question is have you tried the parabolic on the bird calls you are
worrying about? If not, try it. You might save yourself some money.
If you are still set on getting a shotgun, your price range could
probably buy a Sennheiser ME67 off Ebay or used elsewhere. I'd be really
surprised at getting a MKH 416 or 816 in good shape for that little.
Certainly Ebay prices are higher than that.
