Hummingbird Hawk-moth

We were watching the hornet flying about and trying to find one landed when I noticed this up in a small tree about 12'. Upon futher investigation it was this large moth. I of course proceeded to try to get a decent shot straight up with no luck.
The tree he was up in had a trunk of no more than 3 inches but enough height bending it would have damaged it. We finally opted for disturb and hope it lands somewhere more convenient but he went to another tree and we lost sight.

I'm a bit gutted now that I've ID'd this guy tonite...lol
