I've got one, though you might want to use a little higher quality mic.
Especially if you need to do measurement of sound level differences.
That's probably beyond homemade stuff.

A ME 67 is really not the appropriate mic for a parabolic.
A parabolic will give you sharper directionality to help pick things
out. But you probably won't be able to be very far away.

Here you have to decide how precise the analysis you are working on. And
do you expect to publish it? Bioacoustics can get very picky in peer
review as to equipment used. And their ideas are expensive. If you
expect to publish in their circles get advice from them. And have deep
pockets.
For more informal analysis, it will depend on your budget. For low price
with pretty good quality it's hard to beat a consumer minidisc. For a
good deal more money there is the one I use, the HHb Portadisc. And
there are all kinds of up and coming, mostly unknowns with solid state,
hard disk or other storage mediums.
