Hi Goldie,
I agree w/ Photog but it does look like an immature or post-fledgling Great Blue Heron, because your (beautiful I might mention!) photo depicts a bird w/ head plumage lacking the black plumes and shaggy extensions behind the neck as w/ adult breeding which would been seen this time of year. Good birding!
