Aechmophorus occidentalis breeds in the spring. It has a very elaborate courtship behavior. The couple will dance, posture, and run across the water. Many grebes ussually mate at the same time. The female lays three to five bluish white colored eggs. The nest floats on the water in the reeds. Both sexes take care of the young. They become very territorial during nesting. To avoid other nesting pairs the parents dive from the nest and swim underwater to go to feeding grounds.
Average time to hatching: 23 days.
Average eggs per season: 3.
