Lorikeet Feather

There is a bit of a story to this one.
I'd been trying for lorikeet shots amongst the vines at the local park.
I startled a small group who flew off. They are fairly quick and difficult to capture in flight at the best of times.
One of them did leave a calling card.
Managed one shot and not for the want of trying, couldn't get another focus lock !!
The feather disappeared over someones back fence.
