In Britain I saw a dabbling duck following a diving duck (from memory
it was Common Teal following Tufted Duck) feeding on invertebrates and
plant material brought to the surface by the diving ducks activities
on the bottom of the pond. My interpretation was this was
opportunistic on the part of the dabbling ducks and the diving ducks
seemed annoyed by the others following them.
