At high tide, ocean water pours into the salt marshes at the refuge, and provides a fish bonanza to the birds that hover near the sluice gates. I saw a band of Seagulls diving with abandon into the churning water and I began shooting them. Only when I came home and looked at the images on the computer did I see that some of them actually had caught small fish.
A Cormorant was equally successful, though they usually catch much bigger fish. Perhaps this one was young and still learning.
