High ISO with Polarizer

Continuing my practicing photos with high ISO, I headed out to Port Huron.  I figured there would be plenty of action shots between the boats and the birds.  I shot many images of boats going from 'no wake' to wide open and could follow/pan pretty easily with the 200 mm  lens.  I had lots of luck with clarity and had many more good shots than bad.  It was a good beginning.
Shooting the birds in flight was a bit more difficult.  They did not get the memo to fly close to me and in a direction I could use.  At least none of them crapped on me.
I did see some of them guarding the lights, and with the mix of blue sky and white puffys, there were some opportunities.
I wanted to shoot at ISO 1000 but I was using a polarizer, so bumped it down to 800.  With that set up, I had a shutter speed of 1/640.  I always use a polarizer around the water.
What I learned.  I've shot (photographically) a number of Gulls.  There is definition in the chest feathers.  On this shot, there is no definition.  Like he's wearing a T-shirt.  I'm going to take it that in the RAW image with enough time I might be able to bring something out - but I'm OK with this as it is.  There is a lot of white between the Gull, the lamp and the clouds.  All of it is nice and defined.
The final product is cropped pretty tight, if i was going to do something more with this image I might have to take a different approach.
