homemade mics and computer sound card

Hi,
I've just build a couple of mics based on the Panasonic WM61A in order to r=
ecord bird calls at night. Testing with my Fostex FR2-LE, I do get a very g=
ood signal (in fact I am surprised as to how good the signal is!). However,=
 the project would require to record for many hours and I would like to con=
nect those to a computer and record to the hard disk.

Obviously I have a problem in that the signal is so weak as to be totally u=
nuseable.  I realise that most computer sound card are build more for playb=
ack than for recording but there must be some card out there that have a mu=
ch better mic input or a way to amplify the signal and feed it to the line =
input.

If you know a way I should go (or an area that I should pursue my research =
on), please let me know.  Right now, my only option would be to spend the n=
ight in the field to change flash card and batteries in the Fostex!!!  Not =
quite what I'd like to do.

Thanks,

Normand
