Clark's Grebe (Aechmophorus clarkii) in "reed" display, also know as weed ceremony, in a freshwater lake in San Diego County, California, USA, during winter (January).
Female and male Clark’s grebes court one another by “dancing” and exchanging “gifts” of weeds pulled from the water.
Clark’s grebes closely resemble western grebes, and the two species often live in close proximity to one another but rarely mate.

Both male and female Clark’s grebes work together to build a floating nest to hold their eggs along the borders of inland lakes and other waterways that feature thick vegetation like rushes or reeds.
