Barn Owls - where did they come from?

[con <>]

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.
