Yup
You're right about the Harrier,
See post from ONTBIRDS below
" This one was pristine white and was easy to spot on the black soil. While I was watching him in my binoculars I could see a Harrier coming in directly at the Snowy from the north. It wasn't till the last second the Harrier pulled up and flew south across the road. The Snowy wasn't particularly perturbed by this. Shortly the Snowy flew closer and up to the top of a power pole on the side of the road so we had a great look at this beautiful bird.
Great shots by the way Mike.
Right place, Right time.
