could anyone give me a shotgun amp circuit for long range listening? is it really possible to intercept a conversation at 100 feet? i made a few amps but, the background noises are overriding it. like birds,wind etc. are there any filter circuits ? please help.

Are you using a directional microphone? YOu will always have trouble with wind though and any other noise within the cone of reception.

Any low noise opamp makes an excellent mic preamp.
If sounds from birds and wind cause interference then a highpass filter will remove some of the wind rumbling sounds and a lowpass filter will remove some of the bird sounds leaving you with sound like a telephone.
