Parasitic Jaeger?

I was walking along the beach at Higbee Beach this morning when I saw a dark gull flying overhead. I knew something was different about it but it wasn't until it was almost too late that I realized the general shape was wrong. I snapped a couple of quick pictures (this was the best), and I'm thinking this might be a lifer Parasitic Jaeger.

 

Anyone who can confirm?
