Has the tawny frogmouth got any significance as an omen?

I'm curious also. My sister mentioned this to me last summer when a sick Tawny would come to our back porch and spread its wings on the ground, he didn't look healthy.we were hand feeding him...This happened was also the time our mum fell seriously ill. luckly she has since recovered. but our little friend is no longer about. any other stories similar?
