UPDATED to Boat Tailed Grackle not Rusty Blackbird

I ID'd this is a female Rusty Blackbird. That was the best I could do looking at my reference books. Lynne and Hap ID'd it for me, as a Boat Tailed Grackle. Another one for my lifer list.

These photographs were taken standing on John's Pass Boardwalk at Maderia Beach, Florida. These were taken while I was watching the dolphin playing in the ocean a very short distance from the birds.

Look at those feet.

I went to http://www.birds.cornell.edu/AllAboutBirds/BirdGuide/Boat-tailed_Grackle.html

and right there is a photograph that is this bird without a doubt. These photographs were taken on the Gulf Coast, and they have a photo of the Gulf Coast female. Thank you Lynne and Hap, I am sure I will know this bird the next time I see it.
