The name "dipper" comes from their observed habit of feeding.  They completely dip their heads in water many times a minute, a bobbing motion which also continues while above water when looking for food.  They also completely submerse themselves under water, using their long legs to walk across the stream bed; they also use their wings as a swimming aid.  Food consists of aquatic insects and insect larvae, flying insects, and small crustaceans.  Small fish, tadpoles, and worms are sometimes taken, but consist of a small overall proportion of their diet.
