Aechmophorus occidentalis


Western Grebes perform several elaborate dances while mating. In one dance, the two mating birds rapidly begin "running" across the water surface until both birds dive down into the water. In the second dance, the two birds raise their bellies out of the water and carress each other with vegetation held in their bills. These birds lay 3-4 eggs with an incubation period of about 23 days. Fledgings can often be seen riding on the back of the female. These birds feed on small crustaceans and fish.
