This is a hard Gull for me to ID most of the time. They look very similar to a Laughing Gull. Laughing Gulls also like to visit marshes in the Lowcountry so I see them often, a Bonaparte’s Gull not so much.
I shot these during a random drive one day along the Georgia – Florida border.
Moving low like this I was able to catch the shadow as well as the Gull. Actually I was surprised I caught the Gull never mind his shadow.
