Blue-winged Teals are dabbling ducks and often have bits of grass or duckweed hanging from their beaks or heads. The ones at Magnolia Plantation are wary of people and I mostly get photographs of them swimming away.
They do a lot of swimming in circles, creating rings of waves. If you stand still they sometimes come circling back near the shore.
When they are away from the duckweed and the light is right their reflections can be quite pretty.
