The wind has blown the duckweed into the edges of the marsh, and many of the ducks may be seen scooping it up with their beaks. These blue-winged teal were busy feeding this morning. At this time of the year, all the ducks have undergone their first molt, leaving the males looking like their female counterparts (the white feathers in the duckweed are left from molting). This makes it more difficult to tell some of the species apart. The color and shape of the bill, which doesn't change, helps to identify them.
