I'd like to try recording birdsong using a microphone at the focus of
parabolic reflector.
Currently, I'm having difficulty thinking of domestic items which I could
cannibalise for their parabolic shape. Any ideas would be welcome. Best
I've thought of so far is an old radiant heater with the cylindrical
heating
element at the centre of a spun reflector.

Thanks (I am aware of the professionally priced reflectors from Sweden.)

You might try the audio-orientated newsgroups. Perhaps rec.audio.pro or
similar. there's bound to be someone in the trade who's used devices like
you want.
