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.

How about a big torch, the sort that takes a
lantern battery?

Enough room in there also to do a small battery
powered preamplifier.
