Further to Tom Dickson's note.
The possibility of the Barn Owl being responsible
for the Min-Min light in Australia or "Will o' the Wisp" in England was the
subject of a paper by Fred Silcock "A review of
accounts of luminosity in Barn Owls Tyto alba" , in Australian
Raptor Studies 2, 1997, (Birds Australia Monograph No. 3) p40-53 and
edited by Gregory Czechura and Stephen Debus.
This paper included many references.
Some other references are on the WWW
