On 24 December 1979 Bron and I collected 128 road-killed Barn Owls
between Hay and Narrandera (21% Imm M, 42% Imm F, 9% Ad M, 28% Ad F).
All were apparently killed while hunting mice as they crossed the road
(House Mice were in plague at the time). All gut contents that I
examined included only mice; one adult male owl had 6, three of which
had not been completely swallowed at the point of the owl's demise. The
owl population was clearly prospering. The road-kills occurred in
clusters, possibly related to the distance the owls were required to
travel to reach the highway from their day-time roosts along the river
(variable, but generally less than 2km). The only stretch of highway
with no road-kills was a section between Darlington Point and Narrandera
where the river meanders to more than 5km from the road.

Perhaps:
Around the end of April and the beginning of May we drove from
Canberra to Coward Springs, west of Lake Eyre. We counted road kill
including the general catergory of 'birds' of which there were 45.
Most of those 45 were whitish owls. Of these, we stopped to have a
look at 6. All of them were Barn Owls. Most of the Barn Owls were
alongside roads in the Hay Plains area.
